All data available from the Houski API, including regular fields and expansion data sets.
Expansion data sets return sets rather than single values, like a property's assessments across multiple years.
Each field below shows its price and whether it can be sorted, filtered, or predicted, and how full it is in the country or region you choose.
Houski gives every property the same set of fields in every country, so one query works the same everywhere. Choose your country or region to see how much of that set is filled there, and whether it is complete enough for your use. Data updated daily. Where no record exists, Houski estimates the value from the property and its neighbours.

Pick a topic to see its fields.
Pick an industry to see the fields its datasets deliver.
The Filled column of the fields table below is each field's share of properties with a value in the place chosen, with how many properties that is. Each bar is the average fill of the fields that apply in its topic, or of the fields the datasets of its industry deliver. A field that cannot apply here, such as the listing date of a property never listed, is shown in the table but left out of every average. Every figure is also in one JSON file, updated daily.
Every money value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, and pounds sterling for a property in the United Kingdom, when United Kingdom properties are served. Houski applies no exchange rate, and the numbers carry no currency marker, so read the country_abbreviation field to know which currency you have.
The income bands in the demographic fields work the same way. A band such as 100,000 to 149,999 counts Canadian dollars in Canada and United States dollars in the United States, so the same band covers a different real income level in each country and the two percentages do not mean the same thing.
One piece of maths Houski does do: the census income figures are moved to today's dollars. The census reports income in the dollars of its own year, 2021 in Canada and 2024 in the United States, and Houski scales it forward with that country's own consumer price index.
Before you compare, total, or average any money value across countries, convert one side using an exchange rate of your choosing. Billing is separate from all of this and is always in United States dollars, whatever country the data came from.
Listing, rental, assessment, and permit data for properties across every country Houski covers. Expansion rows cost $0.001 each, whatever the row contains, so a full nested record costs the same as one field on the parent property.
| Name | Description | Values | Sortable | Filterable | Source |
|---|---|---|---|---|---|
| expand_estimate_list_price | The price the property was listed for at the given date. It is considered an 'estimate' in our system because we may not have got the exact day of the intial listing or the price change correct, though it generally should be quite accurate. For unlisted events backed by a public sale record, this is the actual price paid in the completed sale rather than an asking price. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea.

| expand_assessment_year | The calendar year in which the property value assessment was conducted. This temporal reference point indicates when the official valuation was determined, providing context for understanding the assessment's recency and relevance to current market conditions. | N/A | Yes | Yes | document |
| expand_assessment_value | The most recent official property tax assessment value available for this property. This figure is the official value a public authority sets on the property, usually as the base of property tax. It may not reflect current market value and is updated on a schedule that varies by jurisdiction. The assessment year corresponding to this value is provided in the separate 'assessment_year' field. No value will appear if assessment data is unavailable for this property. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea. Houski applies no exchange rate, and the number itself carries no currency marker, so read the property's country_abbreviation field to know which currency you have. Before you compare, total, or average this value across countries, convert one side using an exchange rate of your choosing. By country Canada, United States In Canada and the United States this is the value on the property tax roll of the local assessment authority: a city, a county or a provincial assessment agency. Netherlands In the Netherlands this is the valuation of immovable property (WOZ value), which the municipality sets on every home each year for its taxes: by law the price the home would have fetched on the reference date. Latvia In Latvia this is the state's current official valuation, set on 1 January 2025 from 2022 market prices and held at no more than 80 percent of the average price level. Latvia still charges property tax on an older value built on 2012 and 2013 prices, so this figure is not yet its tax base. Slovenia In Slovenia this is the generalised market value the Surveying and Mapping Authority's mass valuation sets on every part of a building, the land under it counted in. Norway In Norway this is the tax value a municipality's property tax list gives the home, which Oslo publishes as a workbook. By law it is 70 percent of the home's valuation, which for most homes is the Tax Administration's estimate of its market value, so it is lower than the price the home would fetch. South Korea In South Korea this is the official price the Ministry of Land, Infrastructure and Transport sets every 1 January on each flat, row house and multi household house, the base of the property tax. A detached house among the Ministry's standard houses takes its standard house price, and other detached houses have no value here. | N/A | Yes | Yes | document |

| expand_permit_application_date | The official date when the application for this permit or license was submitted to the relevant authority. This timestamp marks the initiation of the regulatory approval process and serves as a reference point for tracking application progress and processing timelines. | N/A | Yes | Yes | document |
| expand_permit_content | The content of the official permit or license document. This field contains information from the actual permit or license issued by the regulatory authority, whether it's a development permit, building permit, business license, or other official authorization. Houski removes telephone numbers, email addresses, and the owner, applicant and contact details of private individuals from the record text, and marks each removal in the text as [contact removed] or [name removed]. Contractor, builder and business names stay as issued. | N/A | Yes | Yes | document |
| expand_permit_id | The unique identifier assigned to an official license or permit associated with this property. This reference number may represent a development permit, building permit, business license, or other regulatory authorization relevant to the property's use or development status. The identifier can be used to verify approval status or look up detailed information about authorizations through relevant government agencies. | N/A | Yes | Yes | document |
| expand_permit_type | Categorizes the specific type of permit or license associated with this property. This classification helps distinguish between different regulatory authorizations such as building permits, development approvals, business licenses, occupancy permits, or other official sanctioning documents. | N/A | Yes | Yes | document |
| expand_permit_value | The value of the work the applicant declared on the permit, in whole units of the currency of the property's country. It is the figure for the whole job as the permit states it, such as the construction value of a new house or the cost of a renovation. It is not a permit fee and not a value the authority worked out for itself. No value appears where the permit states none, which is the case for most licences and for the authorities that do not publish the figure. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea.

| province | The provincial or state-level jurisdiction in which the property is located. This field identifies the main division below the national level that the property sits in: a province, a state, a region or the country's equivalent. These divisions often set rules affecting property ownership, taxation, and legal rights. The division provides essential geographic context for regional market analysis, comparable property evaluation, and jurisdictional determination. This field holds the division's full name, such as Ontario or Île-de-France, and its short code is in province_abbreviation. The /location endpoint lists every division of a country. | $0.0001 | N/A | Yes | Yes | No | document | 100.0% 142,856,722 properties |
| property_type | The category of residential or commercial structure on this property, indicating its architectural style and ownership model. This field contains one of the following standardized values: House, Townhouse, Apartment, Duplex, Multiplex, Manufactured, Land, Commercial, or Farm.
By country Canada, United States In Canada and the United States the type comes from the assessment rolls, which name the kind of building, and from listings. United Kingdom In England, Wales and Scotland the type comes from the home's energy performance certificate, which is lodged for one home, so every flat has a row of its own. A flat or maisonette is an Apartment and a park home is Manufactured. A house or bungalow is a House when detached, a Duplex when semi-detached and a Townhouse when terraced. Czechia In Czechia a family house or recreation cottage of one home is a House when its outline shares no wall with another home's building, a Duplex when it is one of a pair, and a Townhouse when it stands in a row. The register counts the flats of a building but gives them no rows of their own, so a building of two or more flats has one row at each of its addresses, typed as the whole building: a Duplex for two flats and a Multiplex for more. Poland In Poland a single family house or summer house at one address point is a House when its outline shares no wall with another home's building, a Duplex when it is one of a pair, and a Townhouse when it stands in a row. A block of flats has one row for the whole building, a Multiplex, and a flat named in a sale deed has a row of its own as an Apartment. Finland In Finland a detached house or a free-time residence of one apartment is a House. The building register counts the apartments of a building but gives them no rows of their own, so a building of two or more apartments, whether a semi-detached pair, a row house (rivitalo) or a block of flats, is typed as the whole building: a Duplex for two apartments and a Multiplex for more. France In France a building of one dwelling in individual residential use is a House when its outline shares no wall with another home's building, a Duplex when it is one of a pair, and a Townhouse when it stands in a row. A building of two or more dwellings has one row at its main address for the whole building, a Duplex for two dwellings and a Multiplex for more, as its flats have no rows of their own. Spain In Spain a residential building of one dwelling is a House when its footprint shares no wall with another home's building, a Duplex when it is one of a pair, and a Townhouse when it stands in a row. The cadastre counts the dwellings of a parcel but gives them no rows of their own, so a building of two or more dwellings has one row at each of its addresses, typed as the whole building: a Duplex for two dwellings and a Multiplex for more. Netherlands In the Netherlands every dwelling of the address register has a row of its own. A dwelling alone in its building is a House when the building shares no wall with another home's building, a Duplex when it is one of a pair, and a Townhouse when it stands in a row. A dwelling in a building of two is a Duplex and one in a building of three or more an Apartment, so the houses of a terrace a municipality drew as one building read as Apartments. Switzerland In Switzerland every dwelling of the federal building and dwelling register has a row of its own. The one dwelling of a residential building is a House and one of two dwellings a Duplex. A dwelling of a residential building of three or more is a Townhouse where every dwelling has its own entrance, a row of houses the register keeps as one building, and an Apartment otherwise. The one dwelling of a building mainly used for something else, such as a caretaker's flat or a farmhouse in a barn, takes an estimate from the homes around it. Norway In Norway every use unit of the cadastre has a row, typed by its building's type. A detached house, a farmhouse or a holiday cabin is a House, a home in a two dwelling house a Duplex, a row, chain or terraced house a Townhouse, a home in another small house of three or more dwellings a Multiplex, and a flat in a block or a service housing centre an Apartment. Slovenia In Slovenia every dwelling the real estate register holds has a row. A dwelling in a one dwelling building is a House when the building stands alone and a Townhouse when it stands at the end or in the middle of a row. A dwelling in a two dwelling building is a Duplex, and a flat is an Apartment in a building of three or more homes and a Duplex in one of two. Estonia In Estonia a house is a House and a section of a row house a Townhouse. A flat is typed by its building's use, a Townhouse in a row house, a Duplex in a two dwelling house and an Apartment in a block of flats, or, where the use names none of those, by its building's dwellings: a Duplex for two and an Apartment for more. Latvia In Latvia the cadastre's use of the dwelling gives the type: a dwelling in a house of three or more dwellings is an Apartment, one in a two dwelling house a Duplex, and a one dwelling house a House. The cadastre does not say whether a house shares a wall, so a terraced house of one dwelling is a House. South Korea In South Korea every unit of a building registered as a collective building is an Apartment, and a registered detached house is a House. Austria In Austria the address register counts no dwellings in a building of flats and does not say whether a house stands alone, so it names no type. A home a listing is matched to takes the type its listing's words name where they name one, and every other home takes an estimate. | $0.0001 |

| property_taxes | The annual property tax amount assessed on this real estate. Property taxes are levied by government authorities and may vary based on location, property value, and applicable exemptions. This figure represents the most recently reported or estimated annual tax obligation. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea. Houski applies no exchange rate, and the number itself carries no currency marker, so read the property's country_abbreviation field to know which currency you have. Before you compare, total, or average this value across countries, convert one side using an exchange rate of your choosing. By country Canada, United States In Canada and the United States this is the bill the taxing authority levied where it publishes one, and otherwise an estimate from the local tax rate and the assessed value, or the bill a listing reports. United Kingdom In England, Wales and Scotland this is the annual council tax for the home's band, from its council's published Band D charge and the band ratios set in law, which in Scotland are higher than in England and Wales from band E up. The band is the one the Valuation Office Agency lists for the home in England and Wales, or the one a listing of the home shows. The Band D charge is the council's average with every precept included, so a home in a parish or community that sets a higher or lower precept pays a little more or less. It is the full charge before any discount, exemption or reduction, such as the 25 percent discount for a single adult, and in Scotland it leaves out the water and sewerage charges billed with the council tax. The charging year runs from April to March, and property_taxes_year is the year it starts in. South Korea In South Korea this is an estimate of the yearly property tax the Local Tax Act levies on the home's official price: the property tax, the urban area part where the home's lot is zoned urban, and the local education tax, at the standard rates for an owner of more than one home. A household that owns only this home pays less. Netherlands In the Netherlands this is an estimate of the municipal property tax the owner pays on the home: its valuation of immovable property (WOZ value) for the tax year times the rate on homes the municipality set for that year. It leaves out the water board's charges and the municipality's sewerage and waste charges. Norway In Norway this is 0 where the municipality levies no property tax on homes. In Oslo it is the property tax the municipality levied on the home for the year, from the property tax list it lays out for public inspection, and 0 where the deduction every home takes covers the home's tax value. Homes in the other municipalities that tax homes have no value, because their tax value is not published. | $0.0010 | N/A | Yes | Yes | No | property_taxes_source | 61.0% 87,182,323 properties |
| postal_code | The official postal code or ZIP code assigned to the property's location by the national postal service. Postal codes are geographic identifiers that facilitate mail sorting and delivery. The format varies by country, and each code is written the way the country's postal service writes it. Postal codes provide geographic grouping at a more granular level than cities but less specific than street addresses. They are often used for demographic analysis, service area determination, and regional market evaluation. By country United States An American home whose own records and street give no ZIP code takes the code of the census ZIP code area its point falls in. Each area is drawn from the ZIP code most addresses of each census block use, so on the homes that do state a code, the area's code is the stated one about 98 times in 100. A ZIP code used only for post office boxes or by one large mailer has no area, so it is never given this way. | $0.0001 | N/A | Yes | Yes | No | postal_code_source | 100.0% 142,852,256 properties |

| maintenance_fee | The recurring fee the property owner pays to the owners' association, condominium corporation, building management or a similar body for shared maintenance and services. This represents the regular contribution required for upkeep of common areas, shared amenities, building maintenance, and other collective services provided by the managing organization. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea. Houski applies no exchange rate, and the number itself carries no currency marker, so read the property's country_abbreviation field to know which currency you have. Before you compare, total, or average this value across countries, convert one side using an exchange rate of your choosing. By country South Korea In South Korea this is the monthly management fee the apartment complex reports, averaged over its latest twelve months and shared among its households: the common management charges and the charge to the long term repair reserve, without each household's own heating, hot water, gas, electricity and water, which are the energy and water cost fields. United Kingdom, Czechia, Poland, Finland, Norway, Slovenia, Netherlands, France, Spain, Austria, Switzerland, Estonia, Latvia In these countries no source states the fee, so a home that is not an apartment is 0 and an apartment takes an estimate. In Norway the monthly shared costs of a cooperative or company share are not read as this fee, because they also pay the housing company's shared debt. | $0.0010 | N/A | Yes | Yes | No | estimate | 100.0% 142,856,722 properties |
| longitude | The geographic coordinate specifying the east-west position of the property on Earth's surface, using the WGS 84 (EPSG:4326) coordinate reference system. Longitude is expressed as a decimal degree value, where positive values indicate locations east of the Prime Meridian and negative values indicate locations west of the Prime Meridian. The valid range is from -180.0 to +180.0 degrees. This coordinate, when paired with latitude, provides precise geospatial positioning for mapping, distance calculations, and location-based analysis. Values are typically stored with 6-7 decimal places of precision, offering accuracy to within approximately 0.1 meters. | $0.0001 | N/A | Yes | Yes | No | document | 100.0% 142,856,722 properties |
| list_price_vs_estimate | The numerical difference between the property's actual current listing price and its AI-estimated market value. This value is calculated by subtracting the estimated list price from the current list price (list_price - estimate_list_price), expressed as an integer in the local currency. \(\text{Price Difference} = \text{Current List Price} - \text{Estimated List Price}\)
A positive value indicates the property is listed above its estimated market value, while a negative value indicates it's listed below the estimate. Null values appear when no current list price is available. | $0.0010 | N/A | Yes | Yes | No | calc'd from other fields | 1.6% 2,280,056 properties Not counted in the averages |
| latitude | The geographic coordinate specifying the north-south position of the property on Earth's surface, using the WGS 84 (EPSG:4326) coordinate reference system. Latitude is expressed as a decimal degree value, where positive values indicate locations north of the equator and negative values indicate locations south of the equator. The valid range is from -90.0 (South Pole) to +90.0 (North Pole). This coordinate, when paired with longitude, provides precise geospatial positioning for mapping, distance calculations, and location-based analysis. Values are typically stored with 6-7 decimal places of precision, offering accuracy to within approximately 0.1 meters. | $0.0001 | N/A | Yes | Yes | No | document | 100.0% 142,856,722 properties |
| land_area_sq_m | The total land area of the property measured in square meters. This metric represents the complete horizontal extent of the land parcel associated with the property, including the building footprint, yard space, driveway, and any other land within the property boundaries. Land area is a fundamental property characteristic that impacts value, development potential, and property tax assessment. Values are stored as positive floating-point numbers with precision to two decimal places. By country United Kingdom In England and Wales a home that stands alone inside the polygon of a freehold title HM Land Registry holds takes that polygon's area. Every other home in England, Wales and Scotland takes an estimate. Spain, France, Austria In Spain and France a house takes the area of its cadastral parcel, the plot with its garden, and in Austria a home takes the area of the one parcel its address is on where no other address shares that parcel. South Korea, Latvia In South Korea a house takes the site area (대지면적) the building register records, and in Latvia a house takes the area of its property's land where the property holds all of it whole. Switzerland, Czechia, Estonia, Finland, Netherlands, Norway, Poland In these countries no open register gives a home's land, so a home takes the plot area its listing states, and every other home an estimate. Slovenia In Slovenia a house's land area is the land cadastre's area of the parcels its building stands on. A yard the cadastre draws as a separate parcel is not counted. A house whose parcel holds the building alone, or holds another building with a home, gets an estimate instead. A flat shares its building's land and gets none of its own. | $0.0010 | N/A | Yes | Yes | No | land_area_sq_m_source | 100.0% 142,856,722 properties |
| interior_sq_m | The total interior living space of the property measured in square meters (m²). This measurement represents the usable interior floor area of the property, typically including all rooms and hallways but excluding exterior walls, unfinished areas, garages, and outdoor spaces. By country United Kingdom In England, Wales and Scotland this is the total floor area the home's energy performance certificate measures, inside the walls and over every storey, or else the floor area its listing states. Netherlands In the Netherlands this is the usable floor area (gebruiksoppervlakte) the address register records for the dwelling, which is measured inside the outer walls and counts the inner walls with the rooms. Slovenia In Slovenia this is the usable floor area (uporabna površina) the real estate register records for the dwelling. Switzerland In Switzerland this is the dwelling's floor area the federal building and dwelling register records. Estonia In Estonia this is the area the address register records for a flat. A house has no area there and takes an estimate. South Korea In South Korea a flat's figure is its exclusive area (전용면적), the floor of the flat alone, without the stairs, corridors and other parts its building shares and without the balcony. A detached house's figure is the gross floor area of every storey the building register records. Poland In Poland a flat's figure is the usable area (powierzchnia użytkowa) its latest sale deed states. A home no deed measures takes the floor area its listing states, and every other home an estimate. Finland In Finland a house of one apartment takes the apartment floor area (huoneistoala) the building register records. A building of several apartments is one row there and takes an estimate. France In France a house takes the living area (surface habitable) its energy performance diagnosis states, and a home with a listing the living area the listing states. Every other home takes an estimate. Spain In Spain the cadastre records only the gross built area (superficie construida), which counts the outer walls, garages and storerooms. For a parcel holding one home the living area is estimated as that gross area times the share of the built area that the useful area (superficie útil) of the area's house listings makes up. Every other home takes an estimate from the homes around it. Czechia In Czechia the register records only the gross floor area of every storey, cellars and garages included. A home with a listing takes the floor area the listing states, and a house without one is estimated as its gross floor area times the living share its matched house listings measure. Latvia In Latvia the cadastre records a flat's total area, a balcony or loggia counted with the rooms, so a flat's figure is estimated as that total area times the share its building's dwellings have without their balconies and terraces. A one dwelling house takes the dwelling area the cadastre records without them. Norway, Austria In Norway and Austria no open register gives a home's floor area, so a home takes the living area its listing states, and every other home an estimate. | $0.0010 | N/A | Yes | Yes | No | interior_sq_m_source | 100.0% 142,856,722 properties |

| estimate_sale_price | The AI-predicted final sale price for this property based on current market conditions and comparable properties. This value is generated by our machine learning model that analyzes numerous property features, location data, and market trends to estimate the price at which a property would likely sell for if it were to sell in the current market. Unlike actual sale prices which are only available for recently sold properties, this estimate is calculated for all properties in our database, providing a consistent basis for comparison and typically reflecting a figure lower than the estimated list price. This value is in the currency of the country the property is in: Canadian dollars for a Canadian property, United States dollars for an American one, pounds sterling for a property in England, Wales or Scotland, euros for one in Latvia, Slovenia, France, Spain, the Netherlands, Finland, Estonia or Austria, Czech koruna for one in Czechia, Polish zloty for one in Poland, Norwegian kroner for one in Norway, Swiss francs for one in Switzerland and South Korean won for one in South Korea. Houski applies no exchange rate, and the number itself carries no currency marker, so read the property's country_abbreviation field to know which currency you have. Before you compare, total, or average this value across countries, convert one side using an exchange rate of your choosing. By country Czechia Czechia publishes no sale price of a home, so the model learns from asking prices moved down by the national median ratio of asking prices to the registered sale prices of flats of the same building type within 500 metres. | $0.0010 | N/A | Yes | Yes | Yes | estimate | 100.0% 142,856,722 properties |

| cap_rate | A key performance metric in real estate investing that measures the potential rate of return on a property based on its income-generating potential. This metric provides a standardized way to compare the profitability of different real estate investments by focusing on the property's net operating income relative to its purchase price. \(\text{Cap Rate} = \frac{\text{Annual Rental Income} - \text{Annual Expenses}}{\text{Total Purchase Price}}\)
Calculated by dividing the annual net operating income (rental income minus operating expenses) by the total purchase price of the property. | $0.0010 | N/A | Yes | Yes | No | calc'd from other fields | 100.0% 142,856,722 properties |

| assessment_value | The most recent official property tax assessment value available for this property. This figure is the official value a public authority sets on the property, usually as the base of property tax. It may not reflect current market value and is updated on a schedule that varies by jurisdiction. The assessment year corresponding to this value is provided in the separate 'assessment_year' field.

Houski applies no exchange rate, and the number itself carries no currency marker, so read the property's country_abbreviation field to know which currency you have. Before you compare, total, or average this value across countries, convert one side using an exchange rate of your choosing. By country Canada, United States In Canada and the United States this is the value on the property tax roll of the local assessment authority: a city, a county or a provincial assessment agency. Netherlands In the Netherlands this is the valuation of immovable property (WOZ value), which the municipality sets on every home each year for its taxes: by law the price the home would have fetched on the reference date. Latvia In Latvia this is the state's current official valuation, set on 1 January 2025 from 2022 market prices and held at no more than 80 percent of the average price level. Latvia still charges property tax on an older value built on 2012 and 2013 prices, so this figure is not yet its tax base. Slovenia In Slovenia this is the generalised market value the Surveying and Mapping Authority's mass valuation sets on every part of a building, the land under it counted in. Norway In Norway this is the tax value a municipality's property tax list gives the home, which Oslo publishes as a workbook. By law it is 70 percent of the home's valuation, which for most homes is the Tax Administration's estimate of its market value, so it is lower than the price the home would fetch. South Korea In South Korea this is the official price the Ministry of Land, Infrastructure and Transport sets every 1 January on each flat, row house and multi household house, the base of the property tax. A detached house among the Ministry's standard houses takes its standard house price, and other detached houses have no value here. | $0.0010 | N/A | Yes | Yes | No | estimate | 60.9% 87,010,679 properties |
