Reevaluate FHA’s existing model documentation for single-family, HECM, and multifamily models to determine whether their current state is acceptable, so that it provides the intended users a thorough understanding of how the model works and also allows new users to assume responsibility for the model’s use (operational procedures). Based on this review, FHA should make adjustments as needed to the model documentation. At a minimum, these adjustments should include appropriate actions taken to address model documentation deficiencies cited in our report.
