FHA Three- and Four-Unit Self-Sufficiency
An owner-occupied three- or four-unit purchase can look attractive because rent from the additional units may help support the payment. FHA underwriting, however, includes a self-sufficiency concept for applicable three- and four-unit properties. The key idea is that documented rental income, after the required vacancy and maintenance treatment, must be sufficient relative to the projected housing payment under HUD rules. Seller-provided rent estimates are not enough; appraisal-supported market rents and lender documentation matter. Because HUD handbooks are updated, always confirm the current Handbook 4000.1 language and the lender's worksheet before making an offer dependent on FHA financing.
Use the number as a screen, not a verdict
Good underwriting is a process of replacing assumptions with verified facts. Save your first-pass estimate, then update it as leases, tax records, insurance quotes, lender terms, appraisals and inspection findings arrive.
