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.
Coverage
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.
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.
Currency
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.
Expansion data sets
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.

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. 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.

Price increase: Upward adjustment of the asking price
Price decrease: Downward revision of the asking price
Unlisted: Removal of the property from active market listings (generally indicates a sale, but could also represent a withdrawn or expired listing where definitive public documentation may be unavailable). Where a public sale record backs the event, the price is the actual amount paid rather than an asking price
Sold: An official record of the transfer confirms the property changed hands on this date, so the date is the sale date and the price is the amount paid rather than an asking price

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.

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.

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.

construction_year
The calendar year in which the primary structure on this property was originally built.
This represents the initial construction completion date and may not reflect subsequent renovations, additions, or rebuilds. For properties with multiple structures, this typically refers to the main building.
This data is sourced from official property records where available, or estimated based on architectural characteristics and neighborhood development patterns.
By country
United Kingdom
In England, Wales and Scotland the energy performance certificate gives most homes only a band of years, such as 1950 to 1966 or before 1900, and a band is never written as a year. So only a home whose certificate states a plain year, most of them new homes, has a recorded year, and every other home takes an estimate.
Czechia, Finland
In Czechia and Finland this is the year of the completion date the building register records, which it writes on the first or last day of the year where only the year is known.
Estonia, Latvia
In Estonia and Latvia this is the year the building was first put into use, as the building register or the cadastre records it.
South Korea
In South Korea this is the year of the building's use approval (사용승인), the day the finished building was approved for use.
Spain
In Spain this is the construction year of the oldest construction on the home's cadastral parcel.
France
In France this is the construction year the land tax office records, which is often rounded for old buildings.
Netherlands, Slovenia
In the Netherlands and Slovenia this is the year built the address register or the real estate register records for the building.
Switzerland
In Switzerland this is the year built the federal building and dwelling register records, which it holds for about half of the residential buildings. Every other home takes an estimate.
Norway, Austria, Poland
In Norway, Austria and Poland no open register gives the year built, so a home takes the year its listing states, and every other home an estimate.

demographic_income_median_pre_tax
A statistical measure representing the median pre-tax household income of the property's area, derived from the census, household survey or income statistics of the property's country.
This demographic indicator provides insight into the economic characteristics of the neighborhood, offering a balanced representation of the local income distribution.
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.
This figure is in today's money. Each source reports income in the money of its own year, the latest year its census, national household survey or income table covers, and Houski scales it forward with that country's consumer price index.
Every figure is the one the country's census or household survey publishes, named by country below. Houski never works an after tax figure out of a before tax one, or a before tax figure out of an after tax one, and takes none from another country. A figure a country does not publish is empty there.
This figure comes from the census areas each country's statistics office publishes. Where an office publishes a figure for a larger area only, such as a municipality, every census area inside it carries that figure, and a field a country's census does not publish is empty there. Any country notes below name the area a country's figure comes from.
By country
Canada
Canada publishes the median and the average, each before and after tax, for each census dissemination area, in the dollars of 2021.
United States
The United States publishes the median and the average before tax only, in the dollars of 2024, because its census survey publishes no after tax income, so the two after tax fields are empty for every American property.
United Kingdom
England and Wales publish the average before tax only, from the official small area income estimates for each middle layer super output area, of about 7,500 residents, in the money of the year to March 2023. Scotland has no household income figure.
Czechia
Czechia publishes the averages before and after tax for whole regions (kraje) only, from the national household survey, and every home of a region carries its region's figures.
Slovenia
Slovenia publishes the average after tax for whole statistical regions only, from the national household survey, and every home of a region carries its region's figure.
Latvia
Latvia publishes the median and the average after tax for whole planning regions only, from the national household survey, and every home of a region carries its region's figures.
France
France publishes the average before and after tax per commune, from the tax administration's income statistics over the census households, and every IRIS area of the commune carries it.
Spain
Spain publishes the average before and after tax for each census section, from the household income atlas.
Netherlands

Austria
Austria publishes the median and the average after tax for whole federal states only, from the national household survey, and every home of a state carries its state's figures.
Estonia
Estonia publishes the average after tax for whole NUTS 3 regions only, and every home of a region carries its region's figure.
Switzerland
Switzerland publishes the averages before and after tax for whole major regions (Grossregionen) only, from the household budget survey, and every home of a region carries its region's figures.
South Korea

The AI-predicted listing 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 be listed if it came on the market today.
Unlike actual list prices which are only available for actively listed properties, this estimate is calculated for all properties in our database, providing a consistent basis for comparison.
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.

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.

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.

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.
