Fannie Mae and Freddie Mac have released the game changing Uniform Appraisal Dataset Version 3.6. (UAD 3.6). This new dataset standardizes the appraisal process by adding dedicated sections for Energy Efficient and Green Features, moving data like solar panels, HVAC type, insulation, and green certifications from free text into structured fields for consistent analysis, improving valuation accuracy, marketability, and promoting sustainable building by making these features’ impact on value clear and database. This major update requires appraisers to document specific details, enhancing transparency for lenders, investors, and buyers in a standardized way, aligning with growing market demand for sustainable homes.
