Multifamily Loans: How to Finance a 2–4 Unit or 5+ Unit Property in 2026

A multifamily loan isn't one product — the loan you can get depends first on how many units you're buying. Finance a 2–4 unit property and you're in residential lending: conventional, FHA, VA, and DSCR loans, and you can even house-hack it as an owner-occupant with as little as 3.5% down. Cross into 5+ units and you're in commercial multifamily, where agency, government, bank, CMBS, bridge, and construction loans get underwritten on the building's income, not just yours.

So before you compare rates, answer three questions: how many units, will you live there, and how much experience do you have? Those decide your lane and which loan fits.

If you're buying a duplex to live in, your path looks nothing like the investor buying a 40-unit building — and this guide covers both, from the first house hack to the commercial loan ladder.

What is a multifamily loan?

A multifamily loan finances a property with two or more units — and the type you qualify for depends first on the unit count, then on whether you'll live there.

There are two lending worlds. A 2–4 unit property is financed like a house — residential loans (conventional, FHA, VA, DSCR) underwritten on your income, credit, and down payment. A property with 5 or more units is commercial multifamily, financed with agency, government, bank, or short-term loans underwritten on the property's income.

That single line — four units or fewer vs. five or more — changes your down payment, rate, term, and whether you can owner-occupy. Almost everything else follows from it.

Here's how the main loan types map to unit count:

2–4 units vs. 5+ units: why the unit count changes everything

At four units and under, you use residential loans underwritten mostly on you — your income, your credit, your down payment. At five units and up, you cross into commercial multifamily, where the loan is underwritten on the property's net operating income (NOI) and its debt-service-coverage ratio (DSCR).

Here's what actually changes when you cross the 5-unit line:

• Down payment. A residential 2–4 unit can go as low as 3.5% down (FHA, owner-occupied) or $0 (VA). A commercial deal typically needs 20%–35% equity.
• What gets underwritten. Residential lenders look at your paycheck and credit. Commercial lenders look at the building's income — can the rent cover the debt with room to spare?
• Rates and terms. Residential loans are often 30-year fixed. Commercial loans usually run 5–30 years with a shorter fixed period, a balloon, or a reset, and they're priced off a spread over an index.
• Recourse. Most residential loans are full-recourse. Many commercial multifamily loans (agency, HUD) are non-recourse, so the property — not your personal assets — backs the debt.
• Owner-occupancy. You can live in a 2–4 unit and finance it as a primary residence. A 5+ unit building is an investment, full stop.

Financing a 2–4 unit property (including house-hacking)

A 2–4 unit property you live in is treated as a residential purchase — which means you can use conventional, FHA, or VA financing, often with a low or even zero down payment. Live in one unit, rent the others, and you're house-hacking.

House-hacking is the biggest opening for a first-time investor, and it comes down to occupancy. Because you'll live there, you qualify for owner-occupied loans:

• FHA. About 3.5% down on a 2–4 unit, with credit scores often accepted around 580. Lenders can count a share of the projected rent from the other units toward your qualifying income.
• VA. $0 down for eligible service members and veterans on a 2–4 unit, as long as you occupy one unit. Projected rent can help you qualify.
• Conventional. As little as 5% down on an owner-occupied 2–4 unit, with no upfront mortgage-insurance premium the way FHA carries.

The math is why people do it: your tenants' rent offsets part of your mortgage, so you're building equity on a property that's close to paying for itself. The catch is you usually have to live there at least a year before you move on and repeat.

Conventional and DSCR loans for small multifamily

If you won't live there, a 2–4 unit is an investment property — financed with either a conventional investor loan or a DSCR loan. The difference is what gets you approved.

Conventional investor loan. Underwritten on your personal income and credit, usually with 20%–25% down. It typically wins the best rate — if you have strong W-2 income and low debt — but every property you finance this way counts against your personal debt-to-income ratio.

DSCR loan. Qualifies on the property's rent instead of your personal income. If the rent covers the debt at the lender's target ratio, you can qualify without tax returns or a job — which is why self-employed investors and anyone scaling a portfolio lean on them. The trade-off is a slightly higher rate and often 20%–25% down.

Rule of thumb: take the conventional loan when your finances are strong and you're buying one or two properties; reach for a DSCR loan when your income is hard to document or you've maxed out the conventional loans you can carry.

Fannie Mae multifamily loans (including Small Balance Loans)

For 5+ unit apartments, Fannie Mae is one of the two top agency/GSE sources — including its Small Balance Loan (SBL) program built for smaller deals, roughly $1 million to $9 million.

Fannie's terms are strong on stabilized, income-producing properties. Typical framing to verify at application:

• Leverage. LTV up to roughly 80%, depending on the market and property.
• Coverage. DSCR generally around 1.25, meaning the NOI should cover debt service with about a 25% cushion.
• Structure. Non-recourse, with fixed-rate and hybrid options and terms commonly ranging from 5 to 30 years.

The SBL tier is where small investors start — it brings agency pricing and non-recourse terms down to a modest building instead of a 200-unit complex. Minimums, LTV caps, and coverage shift by market, so confirm current Fannie Mae Multifamily terms with your lender before you underwrite.

Freddie Mac multifamily loans (Optigo and SBL)

Freddie Mac's Optigo program is the other GSE workhorse for 5+ unit properties, with its own Small Balance Loan tier aimed at smaller apartment deals.

Optigo competes head-to-head with Fannie. Typical Freddie framing, to verify at application:

• Rates. Competitive fixed rates, priced off a spread over the relevant index.
• Leverage and coverage. Up to roughly 80% LTV with a DSCR around 1.20–1.25, often a touch more flexible than Fannie on strong deals.
• Structure. Non-recourse, with a reputation for strength in workforce-housing and affordable markets.

In practice, brokers shop your deal to both agencies and take the better term sheet. Freddie tends to shine on workforce-housing properties, but the gap is deal-specific — confirm current Freddie Mac Multifamily terms rather than assuming one agency wins.

FHA and HUD multifamily loans: 221(d)(4), 223(f)

HUD/FHA multifamily loans are government-insured, long-term, high-leverage, fully amortizing, non-recourse loans for 5+ unit properties. Two programs cover most needs: 223(f) for acquisition or refinance, and 221(d)(4) for new construction or substantial rehab.

The appeal is leverage and duration: HUD loans can run 35–40 years, fully amortizing, at high LTVs, which keeps the payment low and locks your rate for decades.

The trade-off is speed and paperwork. HUD is the slowest, most document-heavy process in multifamily lending — think months, third-party reports, and strict property standards. That makes it a poor fit for a competitive purchase on a tight timeline and a great fit for a patient owner refinancing a stabilized building.

If you can wait, HUD often delivers the cheapest long-term money; if you can't, one of the faster options below usually wins. Confirm current 223(f) and 221(d)(4) terms with a HUD-approved lender before you commit.

Bank, CMBS, and commercial multifamily loans

When agency programs don't fit — the property's too small, too new, or too unusual — local and regional banks, credit unions, and CMBS (conduit) loans finance apartment buildings instead. They're often faster or more flexible, sometimes with recourse.

Bank and credit-union loans. Relationship-based, with shorter terms and balloon payments (say, a 5-year term on a 25-year amortization). Faster to close and more willing to bend on a story deal, but often full-recourse and re-priced when the balloon comes due.

CMBS (conduit) loans. Fixed-rate, non-recourse loans that get pooled and securitized. They can offer strong leverage on larger stabilized properties, but they're rigid on prepayment — expect defeasance or yield maintenance if you sell or refinance early.

Use a bank when you value speed and a relationship; use CMBS when you want a large, fixed, non-recourse loan and can live with the prepayment handcuffs. Together they cover the commercial multifamily and apartment building loans that don't fit an agency box.

Bridge and construction loans for multifamily

Bridge and construction loans are the short-term financing behind value-add and ground-up deals. A bridge loan carries a property through renovation and lease-up until it qualifies for permanent financing; a construction loan funds building it in the first place.

Both are priced for risk and speed rather than the lowest rate:

• Rates and structure. Higher rates than permanent debt, usually interest-only, with 12–36 month terms.
• How they size the loan. Based on the after-repair or stabilized value — what the property will be worth once the plan works — not what it's worth today.
• The exit. You refinance into agency or bank permanent debt once the building hits its numbers. That takeout is the whole plan, so line it up before you borrow.

A multifamily bridge loan makes sense when a property can't yet cover agency debt but will after a reposition; a construction loan is how ground-up deals get built. Just line up the permanent loan that pays it off first.

Multifamily loan rates and terms

Multifamily rates aren't a single number. What you pay depends on the program (agency vs. bank vs. bridge), the unit count, your leverage, your DSCR, and the term.

A few mechanics decide your rate and payment:

• Index plus spread. Commercial rates are usually an index (like a Treasury or SOFR benchmark) plus a spread set by the lender based on risk.
• Fixed vs. floating. Agency and CMBS loans are often fixed; bridge and some bank loans float, so the payment can move.
• Amortization vs. term. A loan can amortize over 30 years but come due (balloon) in 7 or 10 — the amortization sets the payment, the term sets when you refinance.
• Prepayment. Agency and CMBS loans often carry yield maintenance or defeasance, real costs if you sell or refinance early.

Here's a rough map of how the programs compare on structure. Treat the rate column as relative, not a live quote:

Why sweat a fraction of a point? Because the balance is big. Each 1-point move in the mortgage rate adds roughly $65,000–$80,000 in lifetime interest on the median home — and that effect only grows on the larger balances typical of multifamily deals.[1]

Requirements and how to qualify

Qualifying splits along the same fork as everything else. For a residential 2–4 unit loan, lenders look at your credit, income, and down payment. For a 5+ unit commercial loan, they underwrite the property's net operating income (NOI) and debt-service-coverage ratio (DSCR) — plus your reserves and experience.

Here's roughly what each side needs:

• Credit and down payment (2–4 unit). Scores around 580–620+ depending on the loan, and 3.5% to 25% down by program and occupancy.
• DSCR (5+ unit). Lenders generally want a DSCR of at least 1.25 — meaning NOI covers debt service by 1.25x — though some programs allow ~1.20 in strong markets.
• Reserves and experience. Commercial lenders expect cash reserves and usually favor borrowers who've operated multifamily before. First-timers can still get in, often through SBL or a bank relationship.

NOI is the number everything hangs on: it's your rental income minus operating expenses — insurance, property taxes, maintenance, management — before the mortgage. And those operating costs are heavier than most first-time buyers expect.

Clever's research puts a typical owner's non-mortgage costs at about $23,686 a year — roughly $3,336 in insurance and $3,580 in property taxes alone. On a multifamily property, those are exactly the costs that come out of NOI, and a lower NOI means a lower DSCR and a smaller loan.[2]

The takeaway: pad your operating-expense estimate before you assume a property qualifies. An optimistic number inflates your NOI on paper and gets you a smaller loan than you planned.

How to get a multifamily loan, step by step

The path is the same shape whether you're buying a duplex or a 30-unit building — only the paperwork changes. Here's the order:

1. Confirm unit count and occupancy. This sets your lane: residential (2–4) or commercial (5+), owner-occupied or investment.
2. Pick the loan lane. Residential financing for a 2–4 unit; agency, bank, bridge, or construction for 5+.
3. Gather your docs. Personal financials for a 2–4 unit; a rent roll, trailing 12-month statement (T-12), and pro forma for 5+.
4. Get quotes from at least three lenders or brokers. Rates and terms vary widely — shop agency against bank against bridge.
5. Get a term sheet or pre-approval. This tells you your real budget and strengthens your offer.
6. Order the appraisal and close. The lender verifies value and income, then you close and take over.
