The digital property passport

What is really known about your property?

Enter an address. We'll show what public registers say about the building: real transaction prices nearby, a value estimate with its stated accuracy, and a 3D model.

Type anything: a town, street, building number or postcode. Arrow keys pick a suggestion, Enter opens it.

No sign-up, no call from an agent.

What the passport shows

  • Check the value — without a call from an agent

    An estimate based on real transactions nearby. Always with a range and the measured typical error — we never promise more than we know.

  • See real transactions

    Prices from notarial deeds, not from listings. We show the median and spread for the area — never the price of a single flat.

  • Your home in 3D

    The building's shape, storeys and entrances on a 3D map — from survey data.
