A multifamily construction loan funds a new apartment building (or a gut rehab) in stages and is repaid when the finished, leased property is refinanced or sold. For five-plus-unit projects in the United States there are four realistic routes: a bank construction loan, a debt-fund construction loan, a HUD-insured 221(d)(4) loan, and a bank or debt-fund loan paired with an agency forward commitment for the permanent debt. This guide explains how each works, what lenders ask for, and how to test whether your project pencils before you spend money on plans.

Multi-Family USA is a lender-matching service. We do not originate or fund loans. The figures below come from named official sources where we cite them, and are labeled as market-typical, lender-specific ranges where we do not.

How a multifamily construction loan works

You buy or contract the land, pay for entitlements and design with equity, and then close a loan sized to the lesser of a percentage of total project cost (loan-to-cost, LTC) and a percentage of the projected stabilized value (loan-to-value, LTV), usually also capped by a debt-service or debt-yield test. Closing is only the start. The lender funds the budget in draws: the contractor bills, an inspector confirms the work is in place, lien waivers are collected, and the lender releases the approved amount less retainage.

Three mechanics matter more than any other.

Equity goes in first. Most construction lenders require the sponsor’s cash (and often the land) to be spent before loan dollars flow, and they test the loan “in balance” at every draw: remaining loan proceeds plus remaining equity must cover the remaining cost to complete. Fannie Mae’s Multifamily Guide spells this out for its forward commitments, directing lenders to reject change orders that would push combined hard and contingency costs above the construction loan budget, so the construction loan stays in balance (Fannie Mae Multifamily Guide, Section 1903.05).

Interest accrues on the drawn balance only. Early on you owe little interest, and the balance grows with each draw. Because the building produces no rent until units are delivered, the budget includes an interest reserve that pays the loan’s interest through construction and, usually, part of lease-up.

The loan is short. Typical bank and debt-fund construction loans run roughly 24 to 48 months including extensions, which covers building and lease-up but not the long run of a mortgage. Something has to repay it. That something is the takeout.

The four ways to finance multifamily construction

1. Bank construction loan

Community, regional and some national banks make most ground-up apartment construction loans in the US, usually floating over a benchmark such as SOFR (the Secured Overnight Financing Rate, a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities, published each business day by the Federal Reserve Bank of New York). Banks tend to want recourse, a deposit relationship, and a sponsor with a finished-project record in the same product type. Leverage is conservative compared with HUD, and the bank usually requires a full completion and cost-overrun guarantee.

Banks fit sponsors who need speed and flexibility, are building a smaller project (say 20 to 150 units), and are comfortable guaranteeing the loan personally or through a balance-sheet entity.

2. Debt-fund and credit-fund construction loan

Debt funds and mortgage REITs lend at higher leverage than banks, accept more complicated stories (lease-up risk, a thinner track record, tight timelines) and charge for it with a higher spread and fees. Recourse is often limited to completion, carry and bad-act guarantees rather than full repayment, but terms vary widely by lender. They are a common bridge when a bank cannot reach the leverage the project needs, or when speed matters more than cost.

3. HUD 221(d)(4): construction-to-permanent in one insured loan

HUD’s Section 221(d)(4) program insures lenders against loss on loans for the new construction or substantial rehabilitation of rental and cooperative housing with five or more units, and “allows for long-term mortgages (up to 40 years)” (HUD, Descriptions of Multifamily Programs). Because one insured loan covers construction and the permanent term, you skip the refinance risk that stalks a bank loan. The tradeoffs are time, process and compliance.

HUD publishes its sizing ratios in Mortgagee Letters. Mortgagee Letter 2026-1, which creates a Middle Income option for 221(d)(4), lists the following thresholds for new construction and substantial rehab:

Under the MAP Guide, proceeds are sized at the lesser of the requested mortgage, the statutory limit, the amount supportable by debt service, and the amount supportable by the applicable loan-to-value or loan-to-cost ratio (same letter). Statutory mortgage limits vary by unit size, structure type and location (HUD). In practice the DSCR test or the statutory limit, not the headline LTC, frequently decides the loan amount, which is why a model beats a rule of thumb. Our dedicated HUD 221(d)(4) loan page covers eligibility, Davis-Bacon, mortgage insurance premiums and timeline in more detail, and the FHA and HUD financing guide gives the wider program context.

HUD fits experienced sponsors with a long hold, a strong general contractor, and the patience for a months-long underwriting process. It fits poorly when closing speed is the priority or the sponsor is a first-time developer.

4. Construction loan plus an agency forward commitment

Agency forward commitments lock the permanent loan before the building is finished. Freddie Mac’s Multifamily Seller/Servicer Guide describes an unfunded forward commitment under which Freddie Mac commits to locking the interest rate or spread for the permanent mortgage and the seller commits to delivering that mortgage once the project is complete and has met the conditions to conversion. Freddie Mac does not advance construction funds in an unfunded forward commitment, so a construction lender still funds the build (Freddie Mac Guide, Chapter 17A). Fannie Mae describes its forward commitment as a commitment to purchase a permanent mortgage loan for a to-be constructed or rehabilitated property (Fannie Mae Multifamily Guide, Unfunded Forward Commitments, Section 1903).

Conversion has hard tests. Under Freddie Mac’s conventional forward chapter, the property must reach stabilized residential occupancy of 85 percent for the three consecutive months before the conversion package is submitted, and meet the minimum and priced debt coverage ratio. The permanent amount is also capped by the commitment, and Freddie Mac will not forward-commit lease-up or value-add loans under this chapter. A forward commitment can be extended once for six months; anything beyond that is at Freddie Mac’s discretion (Freddie Mac Guide, Chapter 17A). Fannie Mae likewise requires the permanent loan to be no larger than the forward commitment, and reduces it if actual stabilized net cash flow comes in below the original underwriting (Fannie Mae Guide, Section 1903.07C).

Forward commitments are lender-delivered products, and availability, minimum sizes and construction-period terms are set by each agency lender. Ask early.

Terms at a glance

No one set of terms applies to every deal. Treat this as a map of where each route typically sits, and verify against a live term sheet.

Entries marked “typically,” “often” or “roughly” are market-typical ranges, not published program rules. Entries with a source are verified to that source as of October 2026. Use the loan sizing calculator and closing cost calculator to build a first-pass number for your deal, and check current pricing on our rates page.

Interest reserve, draws and contingency

Interest reserve. The reserve is a budget line, not a bonus. Lenders size it from the draw schedule, an assumed rate, and a build-plus-lease-up timeline, and will often stress the rate and the schedule. Because most bank and debt-fund loans float, a rate move or a three-month delay can burn a reserve that looked comfortable at closing. If the reserve runs short, the sponsor must fund the gap, so build a cushion.

Draws. Expect a monthly cycle: pay application from the contractor, third-party inspection, title date-down, lien waivers, then funding. Fannie Mae’s guide calls for a consulting architect to inspect on site regularly with no more than two months between inspections on its forward-commitment construction, a useful picture of how much oversight lenders expect (Fannie Mae Guide, Section 1903.05A). Retainage, commonly 5 to 10 percent, is held back until the work is finished.

Contingency. Lenders expect a hard-cost contingency in the budget and a separate soft-cost contingency. Change orders that would exceed the budget generally require the sponsor to deposit more equity to keep the loan in balance.

Recourse and completion guarantees

Almost every construction lender asks for some form of sponsor guarantee, because the collateral is a half-built building. The three that matter:

• Completion guarantee. The guarantor promises to finish the project, lien-free, on time and on budget, even if the loan runs out.
• Cost-overrun (and carry) guarantee. The guarantor funds budget gaps and, often, interest and operating shortfalls through stabilization.
• Repayment guarantee. Full or partial. Banks commonly require some repayment recourse, especially on smaller deals. Larger, higher-leverage and HUD or agency permanent deals trend toward nonrecourse with “bad-boy” carve-outs.

Guarantor net worth and post-closing liquidity are tested against loan size, and lenders may check the guarantor’s other contingent liabilities. Read the definitions of “completion” and “stabilization” carefully, as they determine when a guarantee burns off.

A worked example (hypothetical numbers)

This example uses round, invented numbers to show how the pieces interact. It is not a quote or a market survey.

The project. A 120-unit garden-style building. Total project cost: $30,000,000 (land, hard costs, soft costs, interest reserve and fees). Projected stabilized NOI after lease-up: $2,000,000. Hypothetical exit cap rate: 5.5%, implying a stabilized value of about $36.4 million.

Option A, bank loan at 65% LTC. Loan: $19,500,000. Sponsor equity: $10,500,000 (35%). Suppose the drawn balance averages 55 percent of the loan across a 24-month build and lease-up, at a hypothetical 8.0% floating rate. Interest carry is roughly $19.5M x 0.55 x 8.0% x 2 years, or about $1.7 million, which has to be inside the $30M budget. The bank would likely require a completion and cost-overrun guarantee and some repayment recourse.

Takeout test. At stabilization, a hypothetical agency-style permanent loan at 1.25x DSCR, 6.0% and a 30-year amortization has a payment constant near 7.19%. Maximum debt service is $2.0M / 1.25 = $1.6M, so the maximum loan is about $1.6M / 0.0719, or roughly $22.3 million. That is a 9.0% debt yield and about 61% of value. Against the $19.5M construction loan, this clears the exit with about $2.8 million of cushion. If NOI came in 10 percent lower at $1.8M, the supportable loan falls to about $20.0 million, still above the construction loan, but the cushion nearly disappears. At $1.6M NOI, the maximum loan is about $17.8 million and the sponsor has to bring a $1.7 million paydown to refinance.

Option B, HUD 221(d)(4) market rate. The 87% LTC ceiling would allow about $26.1 million on paper. Test DSCR next: at 1.15x, debt service can be $2.0M / 1.15, or about $1.74 million. At a hypothetical 6.5% all-in constant (rate, amortization and insurance premium combined), that supports about $26.8 million, so in this example LTC binds and the loan is about $26.1 million, leaving roughly $3.9 million of equity on paper. Real sizing also depends on HUD’s definition of eligible cost, the statutory limit, reserves and any required escrows, so actual equity is usually higher than the arithmetic implies. The trade is leverage and a 40-year term against a longer process and HUD’s compliance requirements.

Takeout: plan the exit before the entry

Most failed construction deals do not fail on the build. They fail because the takeout does not work at delivery. Three questions to answer before closing:

1. At stabilized NOI, how large a permanent loan can the property support? Size it on DSCR and debt yield at today’s rates plus a cushion, not at the rate you hope for.
2. Is there a path to a lock? Freddie Mac and Fannie Mae forward commitments fix the permanent rate or spread early, but conversion requires stabilized occupancy and coverage, so lock only if you are confident in lease-up. HUD 221(d)(4) removes the refinance because the permanent term is part of the same loan.
3. What is the extension runway? If lease-up slips, the construction loan extension terms and the forward commitment extension (Freddie Mac permits one six-month extension under its conventional forward chapter) decide whether you have time.

Agency volume matters here, too. The Federal Housing Finance Agency set 2026 multifamily loan purchase caps of $88 billion for each of Fannie Mae and Freddie Mac, with workforce housing loans excluded from the caps (FHFA, November 24, 2025). That supports permanent takeout capacity, but it does not guarantee your deal gets a quote at your leverage.

Who it fits, and who it does not

A construction loan is likely a fit if:

• You have entitled or entitlement-ready land and a credible budget with a qualified general contractor.
• You or your guarantor have completed projects of similar size and can show liquidity and net worth against the loan.
• Your underwritten stabilized NOI supports permanent debt with room to spare at conservative rates.
• You can fund the equity layer and a contingency without stretching.

It is likely not a fit if:

• You are a first-time developer without an experienced co-sponsor or a strong GC. Lenders will often decline, or require a seasoned partner.
• The deal only works at the optimistic end of rent, cost and schedule assumptions.
• You need to close in a few weeks and want HUD leverage. HUD takes time; a bank or debt fund will be faster.
• The property is a 1 to 4 unit building. That is a different product; see our sister site DSCR Authority for one-to-four-unit investor loans.

What lenders ask for

Expect a request list that includes a development budget and sources and uses, plans and specifications, entitlements and permits, a general contractor agreement and bonding or guarantee details, a third-party market study and appraisal, environmental reports, a construction schedule, a sponsor financial statement and real-estate schedule, and a proposed takeout. Agencies add their own: Freddie Mac asks for a pre-construction analysis report and a narrative summary of the development team’s qualifications for forward commitments (Freddie Mac Guide, Section 17A.3).

Common mistakes

• Sizing to LTC alone and discovering later that the DSCR test or the statutory limit binds.
• Under-funding the interest reserve and ignoring rate and schedule stress.
• Treating the construction loan and takeout as two unrelated decisions.
• Underestimating soft costs, financing fees and carry in “total cost.”
• Signing a completion guarantee without understanding what triggers its release.

Next steps

Start with the takeout: test your stabilized NOI in the loan sizing calculator and check the leverage you can reach on the HUD 221(d)(4) page. If the numbers work, send the project through deal review and we will match it against the lenders in our network that fit your size, leverage and timeline.
