45/159fields of the valuation report, filled from just an address

It looks up the address in the building, address and land registers and draws maps at three scales, with seven map layers from noise to flood risk. It also reads owners and mortgages from the land-register extract.

It fills about a third of the report straight into the office's own Word template, so valuers work as before. The site visit, market analysis and final value stay with them. Kaanon Kinnisvarabüroo OÜ · 2026
