The sales comparison approach is based on the simplest valuation principle: a property is worth as much as comparable properties have actually achieved. It is based on the purchase price collections of the expert committees (Gutachterausschuss) and real estate transaction databases. The procedure is standardized in the ImmoWertV 2022 (§§ 24–26) and delivers the most reliable results given a sufficient comparison database. It is the leading method for condominiums, terraced houses, semi-detached houses and undeveloped plots in well-comparable locations.

Sales comparison value — Procedure:

  • 1. Selection of suitable comparable properties from purchase price collections
  • 2. Adjustment for value-influencing characteristics (location, size, condition, age)
  • 3. Derivation of the adjusted comparison value from the average of comparison prices

The approach is applied within a complete appraisal report; more on this on the page for the market value report.

Which standard land values apply across the catchment area is shown on the pages for local property valuation.
