I built this calculator for the first question to ask before any offer: how far is the asking price from what comparable properties suggest? Enter the asking price, the area and up to three comparable figures in €/m². You will see the range they imply and where the asking price sits. In a valuation I go further — I verify every comparable and adjust it for location, condition, date and terms — but the raw gap tells you whether that work is worth doing.
Asking price vs market value gap
How it works: simple arithmetic on the figures you enter, with no adjustment for location, size, condition, date, tenure or lease terms. Asking prices show what sellers hope for; transaction prices show what buyers paid. Nothing you enter leaves this page.
Why the gap matters: Market value is not price · Market value under IVS · Market value (glossary)
