The quick read: Yes, for projects that qualify, mainly through an existing state or local middle-income program. HUD's middle-income option for Section 221(d)(4) new construction and substantial rehabilitation allows 90% loan-to-cost and a 1.11 debt service coverage ratio, against 87% and 1.15 for a market-rate deal. In exchange, at least half the units are targeted to households earning up to 120% of area median income (AMI) under a recorded use restriction of at least 10 years. On our illustrative $60 million project, that is about $1.75 million more loan and 15% less equity, and the gain survives as long as the restriction cuts underwritten income by less than about 3.5%.
What is HUD's middle-income 221(d)(4) option?
HUD's middle-income 221(d)(4) option is a set of looser underwriting thresholds, 90% loan-to-cost and a 1.11 debt service coverage ratio, for new construction or substantial rehabilitation projects that target at least half their units to households earning up to 120% of AMI under a recorded use restriction tied to a state or local program.
The option lives inside the existing program rather than replacing it. HUD's program description says Section 221(d)(4) insures mortgage loans for the new construction or substantial rehabilitation of rental or cooperative housing with 5 or more units, allows long-term mortgages of up to 40 years, and sets no income limits on who may rent. The same page reports that in fiscal 2024 HUD insured 221(d)(4) mortgages for 105 projects with 17,434 units, totaling $2.5 billion.
Mortgagee Letter 2026-1, dated January 22, 2026, explains why a separate track exists. Under MAP Guide 3.1.12, a middle-income project does not meet HUD's definition of affordable housing, so it would otherwise be underwritten at market-rate thresholds. The letter notes that the industry usually defines middle-income housing as affordable to households earning 60% to 120% of AMI, and that in some high-cost communities households earning as much as 150% of AMI struggle to find rental housing they can afford.
Program (HUD): Section 221(d)(4) new construction or substantial rehabilitation, 5 or more units Maximum mortgage term (HUD): up to 40 years Fiscal 2024 volume (HUD): 105 projects, 17,434 units, $2.5 billion
What did Mortgagee Letter 2026-1 change?
Mortgagee Letter 2026-1 kept the middle-income thresholds HUD first set in January 2025, 90% loan-to-cost, a 1.11 coverage ratio and a 7% vacancy factor, but rebuilt eligibility around existing state, local and military rental programs, required the use restriction to be recorded and survive a sale, and fully superseded Mortgagee Letter 2025-2.
The headline numbers did not move, but the gap over a market-rate deal did. When Mortgagee Letter 2025-2 created the option on January 8, 2025, it compared the middle-income terms against a market-rate 221(d)(4) at 85% loan-to-cost and a 1.176 coverage ratio. The same day, Mortgagee Letter 2025-03 raised market-rate 221(d)(4) leverage to 87% and cut its coverage ratio to 1.15. The 2026 letter compares against those newer figures, so the middle-income advantage is now 3 points of cost and 0.04 of coverage.
The 2026 letter also changed who can use it and how the restriction is enforced:
- Eligibility rests on participation in, and qualification by, an existing state or local middle-income program or a military Rental Partnership Program (RPP).
- HUD reviews the program itself, which must be an existing program with clear objectives, standards, incentives and wide availability to developers.
- All targeted units must be secured by a recorded use restriction that survives a transfer of ownership or a Transfer of Physical Assets of the loan, and HUD requires its Rider to the restrictive covenants unless a regional waiver applies.
- Projects on Defense or Interior Department land acquired or ground-leased in 2025 or later can qualify without a state or local program.
- Section 220 and Section 231 loans are now named as excluded, alongside the health care programs and Risk Share loans.
The letter applies immediately to any application that has not reached initial endorsement.

The middle-income terms match what Mortgagee Letter 2025-03 gives a low-income housing tax credit project with a rent advantage to market, 90% and 1.11, with one difference: the tax credit project is underwritten at a 5% vacancy factor, while the middle-income project keeps the market-rate 7%.
Who qualifies for the middle-income 221(d)(4) option?
A project qualifies when it is a Section 221(d)(4) new construction or substantial rehabilitation loan, takes part in an existing state or local middle-income program or a military Rental Partnership Program, targets at least 50% of units to incomes up to 120% of AMI, and records a use restriction of at least 10 years.
HUD built flexibility into the 50% test because local programs vary. The letter delegates to Regional Center Directors the authority to accept a program that does not fit the guidance exactly. It says restrictions on 20% to 30% of units will generally not be sufficient, while programs restricting 40% or more, especially those that reach lower AMI bands or set clear discounts to market-rate units, should be considered.
The use restriction runs at least 10 years. A Regional Center Director can approve a shorter term when middle-income tenants get enhanced benefits, for example more than 50% of units targeted, but never shorter than 5 years. A state or local government entity must monitor compliance every year, and the state or local program, not HUD, sets the form of the restriction and its compliance rules.
What does not qualify matters as much. The letter says an arrangement that looks like a particular partnership between one developer and a local government body, such as a housing authority, does not qualify even if the AMI targets are met. The option also does not apply to Section 232 health care loans, Section 220, Section 231 or Risk Share loans.
Two paths skip the state or local program. HUD evaluates each military RPP project at application, and the developer must give HUD reasonable assurance that it will keep the middle-income benefit on 50% of units for at least 10 years. A project on Defense or Interior Department land acquired or ground-leased in 2025 or later is generally eligible, with the same 50%, 120% of AMI and 10-year terms.
Units targeted (ML 2026-1): at least 50%, incomes up to 120% of AMI Programs HUD may consider (ML 2026-1): 40% or more of units restricted Minimum use restriction (ML 2026-1): 10 years, waivable to no less than 5
How much more can a middle-income 221(d)(4) project borrow?
On our illustrative $60 million project, the middle-income option raises the loan by about $1.75 million, or 3.6%, when debt service coverage sets the loan, and by $1.8 million, the 3 points of cost, when loan-to-cost sets it, which cuts the equity check by roughly 15%.
HUD sizes every 221(d)(4) loan at the lesser of four amounts: the requested mortgage, the statutory limit, the amount the debt service coverage ratio supports, and the amount the loan-to-cost ratio supports. Moving two of those four tests helps only when one of them is the binding constraint, so run both before assuming the extra leverage.
Illustrative example (our arithmetic, not a quote or a lender offer): a project with $60 million of eligible cost and $3.9 million of underwritten net operating income (NOI) after the 7% vacancy factor. We assume an all-in annual debt constant of 7.0%, covering interest, 40-year amortization and the mortgage insurance premium. That constant is an assumption, not a rate quote; for context, the 10-year Treasury yield was 5.13% on October 21, 2026 (FRED), and the lender sets the note rate.
Table: Illustrative 221(d)(4) sizing, market-rate versus middle-income
| Line | Market-rate | Middle-income, no rent cost | Middle-income, NOI 2% lower |
|---|---|---|---|
| Line Eligible cost | Market-rate $60,000,000 | Middle-income, no rent cost $60,000,000 | Middle-income, NOI 2% lower $60,000,000 |
| Line Underwritten NOI | Market-rate $3,900,000 | Middle-income, no rent cost $3,900,000 | Middle-income, NOI 2% lower $3,822,000 |
| Line Loan at maximum loan-to-cost | Market-rate $52,200,000 | Middle-income, no rent cost $54,000,000 | Middle-income, NOI 2% lower $54,000,000 |
| Line Loan at minimum coverage | Market-rate $48,447,205 | Middle-income, no rent cost $50,193,050 | Middle-income, NOI 2% lower $49,189,189 |
| Line Loan (lesser of the two) | Market-rate $48,447,205 | Middle-income, no rent cost $50,193,050 | Middle-income, NOI 2% lower $49,189,189 |
| Line Equity required | Market-rate $11,552,795 | Middle-income, no rent cost $9,806,950 | Middle-income, NOI 2% lower $10,810,811 |
| Line Change versus market-rate | Market-rate None | Middle-income, no rent cost +$1,745,845 | Middle-income, NOI 2% lower +$741,984 |
Coverage binds in every column here, so the gain tracks the ratio change: 1.15 divided by 1.11 is 3.6% more supportable debt on the same income. If the project's NOI were $4.4 million instead, cost would bind on both sides, at $52.2 million and $54.0 million, and the gain would be the full $1.8 million. Test your own numbers in the loan-to-cost calculator and the DSCR calculator.
What does the middle-income use restriction cost in rent?
The middle-income use restriction costs rent only where the local program's ceiling sits below the rent the project would otherwise collect, because HUD requires no rent advantage analysis; in our example, the restriction can cut underwritten NOI by up to about 3.5% before the option sizes a smaller loan than a market-rate deal.
The break-even comes straight from the two coverage ratios. Dividing 1.11 by 1.15 gives 0.965, so a middle-income project supports at least as much debt as the market-rate version as long as its NOI is no more than 3.5% lower. On $3.9 million of NOI that is $135,652 a year, or about $113 a month of NOI for each of 100 restricted units in a 200-unit building. Past that point the extra leverage is gone, and the restriction still binds the property for at least 10 years.
To see where the ceiling might land, start with HUD's figures. HUD's fiscal 2026 income limits methodology puts the U.S. median family income at $107,900 for a four-person family and adjusts limits by household size, with one person at 70% and two people at 80% of the four-person figure. The rent rule itself comes from your state or local program.
Illustrative ceilings (our arithmetic on the national figure, assuming a program caps rent at 30% of income):
- Four-person household at 120% of AMI: $129,480 a year, or about $3,237 a month
- Two-person household: $103,584 a year, or about $2,590 a month
- One-person household: $90,636 a year, or about $2,266 a month
Your project's numbers will differ because each program uses its own area's median income, its own rent formula and its own rules for matching household size to unit size. Compare each unit type's projected market rent with the program ceiling; where market rent sits below the ceiling, the restriction costs no rent at all.
The other costs are structural. The restriction survives a sale, so any buyer during the term inherits it. A state or local entity checks compliance every year. In return, HUD's letter says it relies on programs that have developed incentives to support middle-income housing, so price whatever incentive your program offers into the same NOI line as the rent you give up.
How do you get a middle-income 221(d)(4) loan placed?
Start with a commercial mortgage brokerage that sizes the same project both ways, market-rate and middle-income, because the right choice turns on whether coverage or cost sets your loan, how much rent your local program's ceiling actually takes, and whether a 10-year recorded restriction fits your hold and exit plan.
Brokerage option first: YieldStack. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Software matches the deal against 20,000+ loan programs and compares the financing options; human brokers structure the deal, negotiate on the borrower's side and carry it toward closing. YieldStack reports a median first offer in under an hour, from an institutional lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Going direct to one HUD lender gets you that lender's read of the program. HUD's program page says 221(d)(4) is eligible for Multifamily Accelerated Processing (MAP), where the sponsor works with a MAP-approved lender that submits the application exhibits to HUD. Whichever route you take, ask to see the deal sized both ways, and confirm early that your local program is one HUD will accept. Background on the program family is on the HUD and FHA loans page and in our guide to 221(d)(4) versus 223(f).
The package that gets a clean middle-income read carries:
- Development budget with eligible cost, and the unit mix by bedroom count
- Pro forma rents by unit type, at market and at the program ceiling
- The state or local program's guidelines, income targets and approval status
- The draft use restriction, its term and who monitors compliance
- Any tax abatement or other incentive the program provides
- Target loan amount, hold period and exit plan
When it is ready, send the middle-income 221(d)(4) deal for review.
The bottom line
HUD's middle-income option raises 221(d)(4) leverage to 90% of cost and lowers the coverage floor to 1.11, against 87% and 1.15 for a market-rate deal, for projects that target half their units to incomes up to 120% of AMI through an existing state or local program. The gain is real but narrow, about 3.5% more loan, and when coverage sets the loan it survives only if the restriction costs less than about 3.5% of NOI. Run both sizings before you commit to a 10-year recorded restriction.
