The Financial Supervision Commission (KNF) issued Recommendation F to establish mandatory criteria for mortgage banks when determining bank-mortgage property values for credit collateral. The document mandates rigorous risk assessment methodologies, requiring independent appraisals that account for long-term market cycles, specific property risks, and prudent valuation discounts. It enforces strict internal controls, including the separation of appraisal functions from credit acquisition and mandatory transparency to ensure regulatory oversight and asset quality.
