Refinancing LIHTC and Affordable Housing with HUD

Affordable properties reach higher leverage and lower coverage requirements under 223(f), but tax credits alone do not qualify you for the affordable tier. How the test actually works.

Primary sources

Owners of LIHTC properties, project based Section 8 properties and other affordable housing have the best terms available in the FHA multifamily programs. The qualification test is more specific than most people expect.

The three tiers

TierMax LTVDSCRVacancy
Market rate, or LIHTC without rent advantage87%1.15x7%
Affordable with rent advantage to market90%1.11x5%
90% or more units with rental assistance90%1.11x3%

Tax credits alone are not enough

A LIHTC property qualifies for the affordable tier only if its restricted rents carry an advantage relative to achievable market rents. The logic is sound: a property whose restricted rents sit well below market has a cushion, because those rents stay collectible if the market softens.

A LIHTC property in a soft submarket where restricted rents are at or above achievable market rents has no such cushion, and is underwritten as market rate at 87% and 1.15x. The appraisal establishes this, so the tier may not be settled until the appraisal is complete.

The rental assistance tier and the 3% vacancy floor

The top tier needs 90% or more of units covered by rental assistance, which in practice means a project based contract rather than tenant held vouchers. The reward is the 3% underwriting vacancy, which is quietly the most valuable line in the table. Underwriting at 3% rather than 7% raises underwritten income by roughly four percent of gross potential rent, and that flows straight into the coverage test.

What else applies to a tax credit deal

  • Subsidy layering review where multiple public subsidies combine.
  • Developer fee treatment, including deferred fee, which has to be structured around HUD's surplus cash rules.
  • Secondary debt structuring for soft loans and public sources.
  • HAP contract renewal analysis on Section 8 properties.
  • Income averaging, which changes the restricted rent mix and therefore the rent advantage analysis.

Year 15 and beyond

Properties coming out of the initial compliance period are often prime candidates. A 35 year fully amortising fixed rate loan suits an asset the sponsor intends to hold for the long term, and the affordable tier terms are the best in the program.

HUD revises mortgagee letters and handbooks frequently; where a provision is a draft rather than operative guidance we say so on the page. This is general information, not legal, tax or financial advice, and not a commitment to lend.

Important disclosures

HUD Refinance is an information resource and is not a government agency. It is not affiliated with or endorsed by the U.S. Department of Housing and Urban Development or the Federal Housing Administration. Nothing on this site is a commitment to lend, an offer of credit, a pre-qualification, or an application for mortgage insurance. FHA mortgage insurance is available only through a HUD-approved MAP or LEAN lender, and all terms are subject to lender underwriting and HUD review and approval.

The program terms summarized here are drawn from HUD mortgagee letters, Federal Register notices, the MAP Guide (Handbook 4430.G) and the Section 232 Handbook (4232.1), each cited on the page where it is used. HUD revises these materials frequently, sometimes without notice, and provisions may be superseded between our review dates. Figures stated as current are current as of October 14, 2026. Loan sizing is always the lowest of several statutory and underwriting tests applied to a specific property, and no figure on this site should be read as the amount any particular project can obtain.

This site does not publish interest rates. Pricing on FHA-insured loans is set at rate lock by then-prevailing market conditions and varies by lender, execution and credit.

Nothing here is legal, tax, accounting, investment or financial advice, and no attorney-client or fiduciary relationship is created by using this site or submitting the inquiry form.
