People at Fannie and Freddie like their bonuses so it is going to happen unless FHFA changes their goals which is highly doubtful since FHFA just confirmed the at their valuation modernization summit on Feb 28th that are proceeding with the rollout of UAD 3.6 beginning in Sept., 2025, which is the same timeline that they published in 4q24. The rollout will be in phases, with limited lenders using UAD 3.6 beginning next September and all lenders allowed to use it beginning in January 2026. The existing UAD dataset and forms can continue to be used until Nov., 2026 (at the lenders' discretion), at which time, all appraisals will have to submitted using UAD 3.6. The new UAD 3.6 specification has been completed and published, so it is almost certain happen without anymore delays.
