HUD 221(d)(4): multifamily construction-to-perm

What does 221(d)(4) finance?

Section 221(d)(4) finances new construction or substantial rehabilitation of multifamily rental properties of five or more units. Conventional market-rate, affordable LIHTC pairings, mixed-income, and senior multifamily are all eligible. The single defining feature is term: interest-only during construction, then 40-year amortization. The construction period is not carved out of the 40 years. It is a fixed-rate non-recourse loan, locked at construction closing, with construction interest funded inside the loan amount and a built-in conversion to permanent at completion. There is no separate take-out underwriting because the loan is already perm.

Loan-to-cost runs up to 87% and 1.15x DSCR on market-rate. Qualifying affordable with a rent advantage, and properties with rental assistance on at least 90% of units, are 90% and 1.11x. LIHTC without a rent advantage stays in the market-rate box. Sponsor equity is the residual. The construction-period interest reserve, working-capital reserve, and operating-deficit reserve are funded inside the loan; the sponsor's out-of-pocket equity at closing is typically the difference between total cost and 87% or 90% loan plus those reserves.

What does the 12 to 18 month timeline look like?

Three phases. Pre-application: feasibility, market study, plan and cost review by the MAP lender, and architectural review. Typically 60 to 120 days. Application: full underwriting submission to HUD, environmental and Davis-Bacon labor-standard determinations, mortgagee's title/legal review. Typically 90 to 180 days. Firm commitment to closing: rate lock, equity bridge, final document negotiation, and closing. Typically 60 to 120 days. Total: 12 to 18 months from MAP lender engagement to construction closing.

The single largest timing variable is HUD queue depth at the regional office processing the deal. Some regions process in 9 to 12 months end-to-end on clean files; others run 18 to 24 months when queues are deep. MAP-lender experience in the specific HUD region is the controllable variable, a strong MAP lender shaves 60 to 120 days off a typical timeline.

What is MIP and how does it affect headline pricing?

Mortgage Insurance Premium is HUD's annual insurance fee added to the loan rate. For multifamily applications submitted or amended on or after October 1, 2025, and not yet initially endorsed, upfront and annual MIP are 25 basis points. The affordable, broadly affordable, and green MIP categories were eliminated.

What can prevent a 221(d)(4) loan from closing?

Davis-Bacon prevailing-wage labor compliance. 221(d)(4) requires Davis-Bacon wages on all construction labor, which can add 5% to 15% to hard-cost depending on metro and trade-union density. Sponsors who underwrite without modeling Davis-Bacon premium re-trade or re-equity at firm commitment. Get the Davis-Bacon wage determination from the MAP lender during pre-application, not after firm commitment.

Environmental review under NEPA. HUD requires a NEPA-level environmental review (more rigorous than ASTM Phase I). Sites with historic resources, floodplain proximity, contamination history, or wetlands often require mitigation plans that add cost and 30 to 90 days. Pre-application environmental screening is the cheapest insurance against late-stage environmental surprises.
