- How does the Rent Check work?
- We model the distribution of asking rents for comparable flats in your district and size, then place your rent on it. The result is your percentile — what share of comparable flats cost less than yours — plus how far you are from the median.
- Where does the data come from?
- Our figures represent market data for each district and flat size — every one dated and shown with its sample, so you can judge it, and so search engines and journalists can cite it. The full method is on the methodology page; dated asking-rent aggregates are available via the free data API. Individual listings and verified signed rents are not available.
- Is it really free?
- Yes — the Rent Check, the Rent Index, and the open dataset are free. The data API is also free and keyless today. Paid business tiers are planned and are not available yet.
- Which cities are covered?
- We're expanding across every major Polish rental market — Warsaw, Kraków, Wrocław, Gdańsk, Poznań and more — district by district.
