To buy a multifamily home with residential financing, you pick a two- to four-unit property, qualify for an FHA, VA, or conventional loan as an owner-occupant, put down between 0% and 25% depending on the program, and commit to living in one of the units. The financing is far friendlier than a commercial investment loan, but every major program enforces occupancy rules, haircuts the rental income you can count toward qualifying, and expects cash reserves on top of your down payment. The 2026 conforming loan limit for a four-unit property in most of the country is $1,601,750, which stretches purchasing power well beyond what most first-time buyers assume.
Pick the Right Loan Program
Three residential loan programs cover two- to four-unit purchases. The one you use shapes your down payment, your insurance costs, and whether the property has to pay for itself on paper.
FHA
FHA is the most accessible route if your savings are thin. You can put down 3.5% on a property with up to four units as long as you occupy one, with a minimum credit score of 580. Scores between 500 and 579 still qualify but require 10% down. FHA charges an upfront mortgage insurance premium of 1.75% of the loan amount plus an annual premium (typically 0.55%) that stays for the life of the loan if you put down less than 10%.
Three- and four-unit FHA purchases face a self-sufficiency test. The appraiser estimates fair market rent for every unit, including the one you plan to live in. FHA subtracts 25% (or the appraiser’s vacancy estimate, whichever is higher) to get net rental income, and your full monthly payment (principal, interest, taxes, insurance, and FHA mortgage insurance) cannot exceed that figure.1Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook The property has to roughly pay for itself before FHA will approve the loan. Duplexes are exempt.
The 2026 FHA loan limits in standard-cost areas are $693,050 for a duplex, $837,700 for a triplex, and $1,041,125 for a four-unit. In high-cost areas, those ceilings rise to $1,599,375, $1,933,200, and $2,402,625.2Department of Housing and Urban Development. HUD Federal Housing Administration Announces 2026 Loan Limits
VA
Eligible veterans and active-duty service members can buy a two- to four-unit property with zero down through the VA loan program. VA loans carry no monthly mortgage insurance, which saves hundreds a month compared to FHA. There is a one-time funding fee running about 1.25% to 3.3% depending on down payment and prior use, and it can be rolled into the loan balance.
You must certify intent to occupy one unit as a primary residence and generally move in within 60 days of closing. The commonly cited one-year occupancy rule is a lender benchmark rather than a hard VA regulation, but moving out in the first few months invites scrutiny. Every unit must pass VA minimum property condition standards, and underwriting on multi-unit VA files tends to be conservative, often requiring cash reserves and discounting rental income at 75%, similar to FHA.
Conventional
Conventional loans backed by Fannie Mae and Freddie Mac offer the widest range of options but demand more from the borrower. The minimum credit score is 620.3Fannie Mae. Eligibility Matrix Through Fannie Mae’s HomeReady program, qualified lower-income borrowers can put as little as 5% down on a two- to four-unit primary residence when the loan runs through Desktop Underwriter.4Fannie Mae. HomeReady Mortgage Product Matrix Standard conventional financing typically requires 15% down on a duplex and 25% on a triplex or fourplex.
The 2026 baseline conforming loan limits are $1,066,250 for a duplex, $1,288,800 for a triplex, and $1,601,750 for a four-unit. In designated high-cost areas, those limits reach $1,599,375, $1,933,200, and $2,402,625.5Fannie Mae. Loan Limits Interest rates on multi-unit conventional loans typically run 0.25% to 0.75% above single-family rates.
What Lenders Want to See
Multifamily borrowers get more scrutiny than single-family buyers because the loan is larger and repayment depends partly on tenants who might leave.
Credit Score
FHA sets the floor at 580 for a 3.5% down payment or 500 with 10% down. Conventional programs require at least 620, though scores in the mid-700s buy meaningfully better rates. Below these thresholds you’re usually looking at a denial or a rate premium steep enough to change whether the property cash-flows.
Debt-to-Income Ratio
Your DTI compares all monthly debt (car payments, student loans, credit cards, the proposed mortgage) against your gross monthly income. The old 43% hard cap under the qualified mortgage rule was replaced in 2022 by a price-based standard, so there is no single universal cutoff. In practice, most conventional lenders prefer a DTI at or below 45%, and FHA generally allows up to 50% with strong compensating factors like substantial reserves or a high credit score.
How Rental Income Counts
Lenders let you count projected rental income from the units you won’t occupy, but they haircut it. Fannie Mae and Freddie Mac multiply the gross monthly rent (from current leases or the appraiser’s market rent estimate) by 75%, effectively assuming 25% will be lost to vacancies and maintenance.6Fannie Mae. Rental Income FHA applies the same 25% reduction or uses the appraiser’s vacancy estimate if it’s higher. If the rent roll shows $3,000 a month, you can only use $2,250 toward qualifying.
Down Payment and Cash Reserves
Down payment minimums vary by loan type: 3.5% for FHA, 0% for VA, and 5% to 25% for conventional. Beyond the down payment, Fannie Mae requires six months of mortgage reserves (principal, interest, taxes, insurance, and any association dues) for all two- to four-unit primary residence transactions.7Fannie Mae. Minimum Reserve Requirements Those reserves must sit in liquid accounts after closing costs are paid. On a $400,000 property with a $2,800 monthly payment, that’s roughly $16,800 in the bank on top of your down payment and closing costs. This is the requirement that catches the most first-time multifamily buyers off guard.
You Actually Have to Live There
Every residential loan program that offers lower rates and down payments on multifamily properties requires you to live in the building. That’s the trade-off. You get residential terms instead of commercial ones, but you cannot treat the property as a pure investment from day one.
FHA is explicit: you must move in within 60 days of closing.8FHA.com. FHA Loan Occupancy Rules to Remember VA and conventional programs enforce similar timelines. At closing, you sign an occupancy affidavit certifying that you intend to live in the property as your primary residence.
This is not a formality. Lying on that document, or buying with residential financing while planning to rent every unit, falls under federal mortgage fraud statutes. 18 U.S.C. § 1014 covers anyone who knowingly makes a false statement to influence a federally related mortgage loan. Penalties include fines up to $1,000,000, imprisonment for up to 30 years, or both.9Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally The lender can also invoke an acceleration clause and demand immediate full repayment. Lenders verify occupancy through address checks, insurance records, and tax filings more aggressively than most buyers realize.
Documents You’ll Need
The paperwork on a multifamily deal is heavier than a single-family one because the lender verifies both your personal finances and the property’s income stream.
Personal Financials
Expect to provide W-2s from the last two years, recent pay stubs, and personal tax returns. If you already own rental property, the lender will focus on Schedule E, which reports rental income and expenses.10Fannie Mae. Income or Loss Reported on IRS Form 1040, Schedule E You’ll also submit 60 days of bank statements showing the source of your down payment and reserves. Large unexplained deposits trigger underwriter questions, so have documentation ready if you received a gift or sold something.
Property Income Records
The seller must provide a rent roll listing each unit’s occupancy, lease terms, and monthly rent. Copies of all signed leases go in the loan package so the lender can verify the numbers aren’t the seller’s optimistic projection. These documents feed the rental income calculation that decides whether you qualify.
The Loan Application
The Uniform Residential Loan Application (Fannie Mae Form 1003) is the core document.11Fannie Mae. Uniform Residential Loan Application Form 1003 Section 4c is where you enter expected monthly rental income for a two- to four-unit primary residence purchase.12Fannie Mae. Uniform Residential Loan Application You transfer numbers from the rent roll and the appraiser’s market rent estimates into this section. Big gaps between what the seller claims and what the appraiser determines can delay or kill the loan, so check the rent roll against comparable listings before submitting.
Don’t Try to Close in an LLC
A common mistake is assuming you can close in the name of an LLC for liability protection. Fannie Mae requires borrowers to be natural persons and that title be taken in the individual borrower’s name, with narrow exceptions for revocable trusts and land trusts.13Fannie Mae. General Borrower Eligibility Requirements FHA and VA have similar restrictions. Some borrowers transfer title into an LLC after closing, but check your loan documents first, because some include a due-on-sale clause that a title change can trigger.
Appraisal and Closing
Once your application is in, the lender orders an appraisal and begins underwriting. This stage is where multifamily deals differ most from single-family purchases.
The Appraisal Looks at Every Unit
The appraiser evaluates every unit in the building, not just yours. Two- to four-unit properties typically use Fannie Mae Form 1025 (Small Residential Income Property Appraisal Report), which includes a comparable rent analysis for each unit. The appraiser measures the property’s rents against similar nearby rentals to test whether the seller’s rent roll reflects market reality.6Fannie Mae. Rental Income If appraised rents come in lower than what the seller claims, the income you can use to qualify drops, and the deal may fall apart unless the seller cuts price.
Underwriting
Underwriting on a multifamily file typically takes three to six weeks. The underwriter cross-checks your income against tax returns, reserves against bank statements, and rental income against the appraiser’s estimates. Expect conditions: requests for more documentation or clarification. Clearing them quickly keeps the timeline on track.
Closing
You must receive a Closing Disclosure at least three business days before closing, detailing every fee you’ll pay.14Consumer Financial Protection Bureau. What Should I Do If I Do Not Get a Closing Disclosure Three Days Before My Mortgage Closing Closing costs on a multifamily property typically run 2% to 5% of the purchase price and include title insurance, lender fees, escrow prepayments for taxes and insurance, and any mortgage insurance premiums. At the table you sign the promissory note, the deed of trust or mortgage, and the occupancy affidavit. Once everything is signed, the lender funds the loan and the deed is recorded with the county.
Insurance the Lender Will Require
A standard homeowner’s policy (HO-3) covers an owner-occupied single-family home. When part of your building houses tenants, that policy isn’t enough. Most lenders require a dwelling policy (DP-3) for the rental portion. The DP-3 covers the structure against most perils but does not automatically include personal property or liability coverage the way a homeowner’s policy does. You typically add liability as a rider, and it’s worth carrying loss-of-rent coverage, which reimburses you for rental income if a covered event makes a unit uninhabitable.
Your tenants’ belongings are not covered by your policy. Requiring renters insurance in your leases protects both parties and reduces the chance of a tenant suing you after a loss. Budget for premiums meaningfully higher than a comparable single-family home, because replacement cost is larger and tenant liability exposure raises the rate.
The Tax Picture
One of the biggest financial advantages of an owner-occupied multifamily is deducting expenses against rental income, something single-family homeowners can’t do.
Splitting Expenses
The IRS treats your building as two properties: the portion you live in and the portion you rent. You split shared expenses (mortgage interest, property taxes, insurance, utilities) by a reasonable method like square footage or number of units. In a duplex with equally sized units, you deduct 50% of the mortgage interest and property taxes as rental expenses on Schedule E, and the other 50% as personal deductions on Schedule A.15Internal Revenue Service. Publication 527, Residential Rental Property Expenses tied only to the rental units (advertising for tenants, repairs to a tenant’s kitchen, property management fees) are fully deductible against rental income.
Depreciation
You can depreciate the rental portion of the building (not the land) over 27.5 years using the straight-line method.15Internal Revenue Service. Publication 527, Residential Rental Property On a $400,000 property where the building accounts for $320,000 and you rent out half, the depreciable portion is $160,000, producing roughly $5,818 per year in depreciation deductions. That reduces taxable rental income even when the property generates positive cash flow, but it also reduces your cost basis, which matters when you sell.
When You Sell
The primary residence exclusion under 26 U.S.C. § 121 lets you exclude up to $250,000 in gain ($500,000 for married couples filing jointly) on the portion you used as your home, provided you owned and lived in it for at least two of the five years before the sale.16Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence The rental portion does not qualify. Gain attributable to the rental units is taxed as a capital gain, and any depreciation you claimed (or could have claimed) on the rental portion is recaptured at a rate of up to 25%.
Landlord Duties Start at Closing
The moment you have tenants, you take on legal obligations that go beyond collecting rent.
Lead Paint Disclosure
If your property was built before 1978, federal law requires you to disclose known lead-based paint hazards to every tenant before they sign a lease. You must provide the EPA pamphlet “Protect Your Family From Lead in Your Home” and include a lead warning statement in the lease.17U.S. Environmental Protection Agency. Lead-Based Paint Disclosure Rule, Section 1018 of Title X Any existing reports or records about lead paint have to be shared too. The requirement applies every time you sign a new lease or renewal, not just the first time.
Fair Housing
The federal Fair Housing Act prohibits discrimination based on race, color, national origin, religion, sex, familial status, and disability. Owner-occupied buildings with four or fewer units have a limited exemption (sometimes called the “Mrs. Murphy exemption”) from certain provisions, but that exemption does not cover discriminatory advertising and does not override state or local fair housing laws, which are often stricter. Treat the Act as applying fully to your property.
State-Law Rules on Deposits and Evictions
Security deposit caps and eviction notice periods are set by state and local law, not federal law, so they vary widely. Maximum deposits range from one month’s rent to no statutory cap depending on the state. Eviction notice periods for nonpayment typically run three to thirty days. Read your jurisdiction’s landlord-tenant code before your first tenant moves in, because getting the notice period wrong can force you to restart an eviction from scratch.
