For every listing we estimate the rent from comparable rental listings: first on the same street, then nearby, then city-wide, and only when that is not enough with a model. Gross yield is the annual rent divided by the asking price. Net yield accounts for registration duty, notary fees including VAT, 5% vacancy, property tax, insurance, service charges and maintenance, for a cash purchase. The median error of the rent estimate for houses is 16.4%. Read the full methodology.
