Fields and expansions

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.

Sale listings

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. 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.	N/A	Yes	Yes	estimate
expand_listing_date	The date when this property was listed for sale on the market. This timestamp marks the beginning of the property's listing period and serves as a reference point for calculating time-on-market metrics.	N/A	Yes	Yes	estimate
expand_listing_event	Identifies the specific market event that triggered the current status of this property listing. This classification tracks significant changes to the property's market presence, providing insights into its listing history and price adjustment patterns. Listed: Initial placement of the property on the market 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	Listed Price decrease Price increase Sold Unlisted	Yes	Yes	estimate

Rental listings

Name	Description	Values	Sortable	Filterable	Source
expand_estimate_rent_monthly	The rental price that 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 initial rental listing or price change correct, though it generally should be quite accurate. 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.	N/A	Yes	Yes	estimate
expand_for_rent_what_is	Specifies which portion of the property is being offered for rent. This field helps categorize rental listings based on whether the entire property or only specific sections are available. This information can be used to filter rental properties based on tenant needs and living space requirements. Entire property: The complete dwelling is available for rent One room: A single bedroom within a shared property Basement: A separate basement unit or suite Main floor: The principal level of the property	Basement Entire property Main floor One room	Yes	Yes	estimate
expand_listing_rent_date	The date when this property was listed for rent. This timestamp marks the beginning of the property's rental listing period and serves as a reference point for calculating time-on-market metrics.	N/A	Yes	Yes	estimate
expand_listing_rent_event	Identifies the specific market event that triggered the current status of this property's rental listing. This classification tracks significant changes to the property's market presence, providing insights into its listing history and price adjustment patterns. Listed: Initial placement of the property on the rental market Price increase: Upward adjustment of the rental price Price decrease: Downward revision of the rental price Unlisted: Removal of the property from active market rental listings (generally indicates the property was rented, but could also represent a withdrawn or expired rental listing)	Listed Price decrease Price increase Unlisted	Yes	Yes	estimate

Assessments

Name	Description	Values	Sortable	Filterable	Source
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

Permits

Name	Description	Values	Sortable	Filterable	Source
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. 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.	N/A	Yes	Yes	document
