FNMA & FHLMC Appraiser Resources, Guidelines, & Regulations
Both FNMA and FHLMC have adopted the Uniform Appraisal Dataset (UAD). The intent or purpose of the UAD is to improve the quality and consistency of appraisal data on loans delivered to the GSEs. At the direction of the Federal Housing Finance Agency (FHFA), FNMA and FHLMC developed the (UAD), which defines all fields required for an appraisal submission for specific appraisal forms and standardizes definitions and responses for a key subset of fields.
