What to do
AWACS interpretation · not source languageWhat to review: No change in this bulletin is mandatory, so first review what it allows: National MI TrueGuide loans with 3-4 units now follow GSE requirements instead of a separate DTI overlay, ADU requirements are presented in a simplified form aligned with GSE eligibility, and UAD 3.6 appraisal forms are accepted with appraisal review deferring to the GSEs.
QC implications
- For National MI TrueGuide loans with 3-4 units, check that the file follows the applicable GSE requirements. National MI's own DTI overlay for these units is removed.
- For ADU properties, check that eligibility was assessed against the simplified ADU presentation, which is aligned with GSE eligibility.
- For loans with appraisals on UAD 3.6 forms, check that appraisal review followed the applicable GSE requirements. National MI will accept the new forms.
