The Housing Corporations Authority (Aw) publishes today the validation report of the market valuation handbook 2024. It shows that this year the highest validation score has been achieved since the existence of the market valuation handbook.
Corporations can choose between two approaches according to the handbook: the basic version and the full version. The basic version is a model-based methodology for determining market value. In the full version, certain appraisal parameters can deviate from the basic version. However, the full version must be assessed by an appraiser.
Every year, ABF/Calcasa conducts a validation on the basic version. The core question is whether the methodology and standards of the basic version lead to a good market valuation. To test this, the market valuations of corporations that have valued the real estate with the full version are used. The accountants require a minimum score of 90% within a margin of 10% (difference between basic and full). This years validation report shows a score of 97% within a margin of 10%. This is the highest validation score achieved since the existence of the market valuation handbook.
The market valuation handbook will be prepared one more time for the reporting year 2025, see the previous announcements about this: Market valuation of corporate ownership becomes easier. The draft market valuation handbook 2025 will be published on October 31, 2025. The definitive market valuation handbook 2025, in which the parameters of vacant value increase, market rent, and discount rate are updated, will follow on March 15, 2026.
