House valuation: available cities

You can classify single- and two-family homes in the cities listed below with your own indicative DDORF estimate. There too, the specific address must be covered by the model. No market value report according to § 194 BauGB; land alone and entire apartment buildings are not included in this calculator.

Which tool suits your task?

When you buy, you start with additional costs and equity. When renting, check returns and liquidity separately. A document checklist, exposé draft and handover protocol help with sales. A calculation result is not a financing commitment, tax advice or market value assessment.

Your entries remain your details

The new templates and the sell-or-rent comparison run in this browser view without saving or sharing. Example figures are assumptions, not measured market values. Other tools explain their respective data basis on their own page.
