Federation of Real Estate Agency

The price monitoring service has grown into one of Finland’s most influential data services

The Federation of Real Estate Agency (KVKL) has been collecting data on completed housing transactions since 1999. The price monitoring service is a browser-based web service and data repository where completed housing transactions can be searched using a wide range of criteria, such as location, plot size, or year of construction. The service enables analysis of transaction data and produces clear reports that real estate agents can use directly in their client work.

Data is automatically collected into the service from the systems of real estate agencies and construction companies. After collection, the data is reviewed, geocoded, and published for users. In addition, various data quality assurance procedures are applied to ensure that both the service and the conclusions drawn from it are as reliable as possible. By the end of 2025, the service contained information on more than 1.8 million completed transactions.

A key service for the functioning of the housing market

The price monitoring service is an essential part of the functioning infrastructure of the housing market. It gathers scattered data generated by real estate agencies and construction companies into a single centralized data repository, enabling efficient use and analysis of the information. The service increases the transparency and reliability of the housing market, as housing price data is based on completed transactions and is available to market professionals in a consistent format.

“According to our strategy, improving the user experience in utilizing data is at the core of everything we do. The data from the price monitoring service also plays an extremely important societal role. Producing housing market information to support societal decision-making is hugely important for the development of housing and housing markets,” says CEO Tuomas Viljamaa from Federation of Real Estate Agency.

“The real estate brokerage sector does significant work in collecting data. Together with Exove, the association has developed the price monitoring service with a user-centric approach, taking data quality improvement and utilization to a completely new level both societally and commercially,” Viljamaa notes.

One dataset, multiple channels

In addition to the browser-based service, real-time APIs are available, allowing key customer groups to utilize the collected and cleaned data within their own applications.

For Federation of Real Estate Agency’s internal statistics, the data has been integrated into the Microsoft Power BI reporting environment, enabling regular and comprehensive reports for association members. Based on these reports, the Federation of Real Estate Agency publishes monthly housing market review releases for the media using analyzed data from the previous month. They also publishes reports on the holiday home market as well as semi-annual and annual reviews.

“Our review releases receive considerable visibility in both national and local media across Finland, and the price monitoring service’s data is frequently referenced in media coverage. We also receive many inquiries from journalists across the country related to housing transaction data. The price monitoring service has established itself as one of the most trusted sources of housing market information in Finland,” says Communications Strategist Anna Haikarainen.

The use of artificial intelligence in refining and analyzing the data has also begun. Initial experiments have been conducted by structuring renovation information—reported in varying formats—using large language models. During 2026, AI will become widely visible to users as a support tool for analysis.

An everyday tool for housing market professionals

The service is designed especially for housing market professionals and has thousands of users every week:

• Real estate agents use completed sales prices and property details—such as construction year and building type—when estimating the price level of new listings. The service also provides insights into regional demand and transaction activity and serves as an important tool for business planning.

• Construction companies use the data when planning and pricing new development projects. The service helps evaluate where new properties should be built and what price levels can be expected in the market. Information about new developments is also included, enabling a comprehensive view of the market situation.

• Banks use the data for loan and collateral evaluations. Legally required collateral value assessments rely on reliable market data, and the service is a key part of this EU-regulated process.

• Researchers and research institutions use the dataset in housing market research.

• Media organizations use Federation of Real Estate Agency’s published data when reporting on housing markets, such as developments in housing transactions in specific regions.

A cornerstone of strategy and business

Data services are at the center of the Federation of Real Estate Agency’s strategy. The price monitoring service is not only a vital tool for professionals but also a key instrument for Federation of Real Estate Agency’s public influence: media visibility of the association’s housing market reports increased by 42% in 2025 compared to the previous year.

The service is also an exceptional example of successful data commercialization. The service and its data have clear pricing models, and the resulting revenue stream enables continued investment in data services development and areas such as cybersecurity in line with increasingly strict regulation.

Long-term development with Exove

The service has been developed together with Exove since 2015 and underwent a comprehensive renewal in 2025. The focus of the renewal was a full modernization of the user interface while retaining the features essential for professionals. The update also enabled significantly easier use across all devices.

The service is built on open-source technologies: data is collected and cleaned into a MongoDB document database using APIs and data-collection agents. The backend system and APIs are implemented with Node.js, and the user interface is built with React. The entire service runs in the cloud provided by the Finnish cloud provider UpCloud.
