Frequent questions

    Getting an apartment estimate pricing online is completely free. Use our estimate tool to provide basic information about the property, and you will receive an estimated apartment value and a detailed downloadable PDF price report in seconds. Plus, once a month, you will receive an update on the property value - completely free of charge.

    The free online real estate price calculator works based on a sophisticated in-house artificial intelligence algorithm that analyzes real estate market data, incorporating at least hundreds of thousands of listings from the major advertising portals.


    Pricing is created based on the following:

    - the unique sales listings from portals;

    - the features of the apartment (such as location, square footage, the standard of finish, floor, year of construction, or the availability of an elevator in the building);

    - the current transaction prices of similar apartments in the area.

    The tool instantaneously compiles similar apartment data in the area. Then, it estimates the value of the property depending on various factors - this way. As a result, the client gets a reliable and up-to-date valuation every time.  

    Offer prices are the prices quoted in the listings. These values reflect the sellers’ expectations and are subject to negotiation.

    The final sale prices - and consequently the transaction prices - are often significantly lower. According to data from the National Bank of Poland, the advertised prices differ from transaction prices by 8 to 17%. The final apartment’s selling price depends on many factors, for example, negotiating skills and the offer’s appeal compared to others. Furthermore, in many cases, a middleman’s commission is due, which further reduces the amount the seller ultimately receives.
