FHA Loan for Multifamily Property: 4-Unit Rules

Yes, an FHA loan can finance a multifamily property with four units, provided the borrower meets the programme’s requirements. The key distinction is that the loan is intended for an owner-occupant: you must live in one of the units rather than buy the property solely as an investment.

That makes an FHA loan for a four-unit property a way to combine a home purchase with rental housing—but the details matter. This guide explains the core occupancy rule and what to consider before applying, so you can assess whether a four-unit property fits your plans.

• 1–4 units Stated FHA-eligible residential property size
• 3.5% Down payment minimum with a qualifying credit score
• 580 Qualifying credit-score threshold stated for the 3.5% down payment
• 1 year Minimum owner-occupancy period stated in the source material
• 5 or more units Property size generally directed to commercial financing or a separate HUD multifamily mortgage program

What multifamily properties can an FHA loan finance?

An FHA loan can finance a residential property with one to four housing units, provided the borrower occupies at least one unit as a primary residence. That includes a duplex with 2 units, a triplex with 3, or a fourplex with 4.

The FHA’s 1–4-unit limit makes owner-occupancy the key distinction: the loan is for a home the borrower lives in, not a property bought solely as an investment. The other units may be rented, but at least one must serve as the borrower’s primary residence.

What happens above four units?

A residential property with 5 or more units generally falls outside the standard FHA loan category for homes with up to four units. Buyers of those properties typically need commercial financing or a separate HUD multifamily mortgage program.

How much down payment does an FHA multifamily loan require?

Minimum down payment

An FHA loan for an eligible 2-, 3- or 4-unit property can require as little as 3.5% down, but that minimum is not a guarantee of approval for every borrower or home. FHA financing is for an owner-occupant: at least one borrower must live in a unit as their primary residence.

Before budgeting, ask a lender to check the FHA loan limit for the property’s location and unit count; the supplied information does not specify a limit amount. The down payment is only one part of the cash needed to buy and maintain a multifamily home.

• 2-unit property: Include the down payment and the costs of buying and maintaining both units.
• 3-unit property: Budget for the down payment and upkeep across three units.
• 4-unit property: Compare the down payment with the full purchase and maintenance costs for all four units.

Credit-score threshold

The 3.5% minimum down payment is available with a qualifying credit score of at least 580. A score below 580 does not meet that stated threshold for the 3.5% minimum, and meeting it alone does not establish that a borrower or property qualifies; confirm the requirements and applicable loan limit with a lender.

What occupancy rules apply to an FHA loan for multiple units?

An FHA loan for a property with up to four units requires at least one borrower to occupy one unit as their primary residence; it is not intended for a purchase made solely as an investment. The borrower must live in that unit for at least one year, whether the home is a duplex with 2 units, a triplex with 3, or a fourplex with 4.

FHA occupancy rules also describe moving into the property within 60 days of closing. Confirm that deadline with the lender handling your application, since the lender can clarify how it applies to your loan.

While living in one unit, the borrower may rent out the remaining units. This arrangement lets an owner-occupant live in a two-, three- or four-unit property and have tenants in the other units, but it does not remove the primary-residence requirement.

How does owner-occupied FHA financing differ from an investment loan?

An FHA loan for a duplex, triplex or fourplex is owner-occupied financing: a borrower must live in one unit as their primary residence, while an investment loan is for a property the borrower does not live in. The FHA option covers buildings with one to four units, including 2-unit duplexes, 3-unit triplexes and 4-unit fourplexes.

• Owner-occupied FHA purchase: The borrower must make one unit their primary residence and live in the property for at least one year. The other units may be rented to tenants; rental income does not remove the requirement to occupy a unit.
• Investment-only purchase: Buying a duplex, triplex or fourplex strictly to rent out every unit does not meet the FHA occupancy purpose. The borrower must live in the property, not simply own it and rent it to others.
• Building with 5 or more units: This falls outside the stated FHA limit of four units. The financing alternatives identified are commercial financing or a separate HUD multifamily mortgage program.

The dividing line is both the borrower’s use of the property and its unit count: an FHA-financed fourplex can include rental units, but the borrower still has to occupy one as a primary residence. A 5-unit building instead points to commercial or HUD multifamily financing, not the FHA 1-to-4-unit route.

When does FHA financing for a multifamily property not work?

Occupancy and unit-count limits

FHA financing for a multifamily property does not work if the buyer will live in none of the units, the property has five or more units, or the buyer cannot meet the applicable credit requirement for the stated 3.5% minimum down payment. These limits make the FHA option an owner-occupied home loan for properties with one to four units—not a general-purpose investment loan.

• Occupancy: At least one borrower must use one unit as a primary residence. A buyer planning to occupy none of the units does not meet this requirement.
• Unit count: FHA home-loan financing covers one- to four-unit properties, including duplexes, triplexes and fourplexes. A property with five or more units is outside that stated range.
• Credit score and down payment: The minimum down payment can be 3.5% with a qualifying credit score of at least 580. The supplied information does not establish eligibility below 580.
• Rental income: Rent from other units may be relevant, but the supplied information does not say how a lender must count projected rent. Do not assume that expected rental income will secure approval.

For a property with five or more units, the supplied material points to commercial financing or a separate HUD multifamily mortgage program as alternatives. The FHA option described here also requires the occupying borrower to live in a unit for at least one year.

What should a buyer verify before applying?

Before applying for an FHA loan, verify that the property has one to four housing units, that you can meet the occupancy requirement, and that your credit score and down payment meet the lender’s terms. These checks determine whether the building fits the FHA’s 2–4-unit route or calls for different financing.

• Count and classify the units: Confirm the property has no more than four housing units and whether it is a duplex (2), triplex (3) or fourplex (4). Ask the lender to confirm that the property qualifies under the one-to-four-unit limit.
• Check credit and cash needed: Ask the lender to verify your credit score against the 580 threshold and confirm the down payment required for your application. The minimum can be as low as 3.5% with a qualifying score of at least 580; do not assume that the lowest down payment applies until the lender confirms it.
• Confirm when you must move in: Ask the lender to state the move-in deadline and confirm that you must occupy one unit as your primary residence for at least one year. Get the timing clear before signing a purchase agreement.
• Find another route for larger buildings: A property with five or more units is outside the FHA one-to-four-unit limit. Ask about commercial financing or the separate HUD multifamily mortgage route.
