Buying a duplex, triplex or fourplex can give you a place to call home while earning rental income from the other units. And with an FHA loan, you may be able to make that goal more achievable with a down payment as low as 3.5% if you qualify.
You’ll need to live in one of the units as your primary residence, but you can rent out the others. In some cases, that rental income can also help you qualify for the loan.
There are a few additional FHA rules to understand when buying a multi-unit home, especially if you’re considering a triplex or fourplex. Here’s what to know before you start your search.
What is an FHA multifamily loan?
An FHA multifamily loan is a common way to describe a standard FHA loan used to buy a home with two to four separate living units. That includes duplexes, triplexes and fourplexes.
FHA technically considers properties with one to four units part of its single-family housing program. Properties with five or more units fall under separate HUD/FHA multifamily programs.
For a homebuyer, the important distinction is simple: You can use a standard FHA loan to buy a property with up to four units as long as you plan to make one of those units your primary residence.
This setup is sometimes called “house hacking.” You live in one unit and rent out the others, giving you the opportunity to earn rental income that can help offset your housing costs. Eligible rental income may also be considered when your lender determines how much you qualify to borrow.
FHA Multifamily Loan Requirements
Most standard FHA loan requirements still apply when you’re purchasing a two- to four-unit home. But multi-unit properties come with a few additional considerations.
Let’s walk through the most important ones.
1. You need to live in one of the units
An FHA loan is designed to finance your primary residence, not a property purchased solely as an investment.
That means you need to plan to live in one of the property's units as your primary home. You can rent out the remaining units.
If you're looking for financing for a property where you won't live, an FHA owner-occupied loan generally isn't the right option.
2. Your down payment could be as low as 3.5%
FHA loans can allow a minimum down payment of 3.5% when you meet the applicable credit requirements.
One of the biggest advantages for a multifamily buyer is that the minimum percentage doesn't automatically jump just because you're buying two, three or four units.
For example, a $400,000 duplex with a 3.5% minimum down payment would require $14,000 toward the down payment before accounting for closing costs and other expenses.
However, there are down payment assistance options available.
3. You'll need to meet credit requirements
FHA guidelines permit a minimum credit score of 580 for the 3.5% minimum down payment. Scores between 500 and 579 generally require at least 10% down.
Individual lenders can set their own credit requirements above FHA's minimums, so qualifying standards can vary. Neighbors Bank typically requires a credit score of 620.
4. Your income and debts still matter
Your lender will review your income and existing monthly debts to help determine your eligibility for financing and the loan amount you may qualify for.
This is commonly measured with your debt-to-income ratio, or DTI. Your DTI compares your monthly debt payments with your gross monthly income.
There isn't one DTI number that guarantees FHA approval. Your full financial picture matters, and FHA underwriting can allow flexibility depending on the circumstances.
A multifamily property also adds another important piece to the equation: rental income.
Can rental income help you qualify for an FHA multifamily loan?
Potentially, yes.
When you buy a multifamily home, your lender may be able to consider eligible rental income from the property's other units when determining whether you qualify.
That's an important advantage for buyers who couldn't comfortably qualify based only on their employment income.
But you shouldn't simply take the advertised rent for the other units and add all of it to your income. FHA has specific rules for documenting and calculating rental income, and the amount your lender can use may be different from the rent you expect to collect. Learn more about using rental income to qualify for an FHA loan, including how that income may be calculated.
Your lender and the FHA appraisal can help establish the eligible rental income for the property.
What is the FHA self-sufficiency test?
The FHA self-sufficiency test is an additional requirement for properties with three or four units.
In simple terms, FHA wants to see that the property's expected rental income is enough to support its monthly housing payment.
To calculate net self-sufficiency rental income, the lender starts with the appraiser's estimate of fair-market rent for all of the property's units, including the unit you'll live in. It then subtracts the greater of:
25% of the fair-market rent, or
The appraiser's estimate for vacancies and maintenance.
The resulting net rental income is compared with the property's monthly principal, interest, taxes and insurance, commonly called PITI.
FHA self-sufficiency test example
Imagine you're buying a triplex and the FHA appraisal estimates market rent of $1,500 per month for each unit.
The total estimated market rent would be:
$1,500 × 3 = $4,500 per month
If the 25% adjustment is used:
$4,500 × 75% = $3,375 in net self-sufficiency rental income
The property's monthly PITI would generally need to be no more than $3,375 to pass the test.
This example is only meant to show how the calculation works. Your lender will use the appraisal and your actual loan details to determine whether a property meets FHA guidelines.
Does a duplex need to pass the FHA self-sufficiency test?
No. FHA's self-sufficiency requirement applies to three- and four-unit properties, not duplexes.
That's one reason it's helpful to talk with your lender about the property type you're considering before making an offer. A triplex or fourplex has a few extra guidelines that don't apply to a two-unit home.
Do FHA multifamily loans require cash reserves?
If you're purchasing a three- or four-unit property, FHA requires documented reserves equal to three months of PITI after closing.
Think of reserves as money you still have available after you've paid your down payment and closing costs. They're a financial cushion for your housing payment after you become a homeowner.
For example, if the property's monthly PITI is $3,000, three months would equal $9,000 in required reserves.
This requirement makes planning your cash especially important. The 3.5% minimum down payment may be only one part of the money you'll need to comfortably purchase a triplex or fourplex.
2026 FHA Multifamily Loan Limits
FHA limits how much you can borrow, and those limits are higher for properties with more units.
For 2026, the national FHA loan limits for two- to four-unit properties are:
Property | Low-Cost Area | High-Cost Area |
Duplex (2 units) | $693,050 | $1,599,375 |
Triplex (3 units) | $837,700 | $1,933,200 |
Fourplex (4 units) | $1,041,125 | $2,402,625 |
These are the national floor and ceiling amounts. Your actual FHA loan limit depends on where the property is located, and some areas have limits between these amounts. Special higher limits also apply in Alaska, Hawaii, Guam and the U.S. Virgin Islands.
Because FHA loan limits can change each year, check the current FHA loan limit for the county where you're planning to buy.
Does an FHA multifamily property need an appraisal?
Yes. An FHA appraisal is required.
The appraisal helps establish the property's value and determines whether the home meets FHA property requirements. For a multifamily purchase, the appraisal can also provide rental information used during underwriting.
An FHA appraisal isn't the same thing as a home inspection. The appraiser is evaluating the property for FHA lending purposes. A home inspection is a separate, more detailed look at the home's condition for your benefit as the buyer.
Does an FHA multifamily loan require mortgage insurance?
Yes. FHA loans require mortgage insurance.
You'll generally pay an upfront mortgage insurance premium as well as an annual mortgage insurance premium that's typically divided across your monthly payments.
Mortgage insurance is one of the tradeoffs that comes with FHA's smaller down payment and more flexible qualification guidelines, so include it when you're comparing your expected monthly costs.
Pros and Cons of FHA Multifamily Loans
An FHA loan can make buying a multi-unit home more achievable, especially if saving for a large down payment has been an obstacle. But there are additional costs and responsibilities to consider before deciding whether it fits your goals.
Pros | Cons |
Down payment as low as 3.5%. You may be able to buy a two- to four-unit home without saving for a large down payment. | FHA mortgage insurance is required. Mortgage insurance adds to your upfront and monthly costs. |
Potential rental income. Renting out the other units can help offset some of your housing costs, and eligible rental income may help you qualify. | You must live in the property. You need to use one unit as your primary residence, so FHA financing isn't designed for a property purchased solely as an investment. |
More flexible credit guidelines. FHA financing can provide another path to homeownership for buyers who may have difficulty qualifying for conventional financing. | Triplexes and fourplexes have extra requirements. These properties must meet FHA's self-sufficiency test, and you'll need qualifying cash reserves after closing. |
One loan can finance up to four units. You can purchase a duplex, triplex or fourplex while still using residential FHA financing. | Being a landlord comes with responsibilities. You'll need to plan for tenants, maintenance, vacancies and other costs that come with owning rental units. |
An FHA multifamily loan can be especially appealing when your goal is to become a homeowner while earning rental income from the same property. The key is looking beyond the low down payment and making sure you're comfortable with the full monthly cost and the responsibilities of owning a multi-unit home.
FHA Loans vs. Conventional Loans for Multifamily Homes
FHA isn't the only way to finance a two- to four-unit property.
A conventional loan may make sense for some buyers, particularly those with stronger credit or enough savings for a larger down payment. Conventional financing also follows different rules for mortgage insurance, rental income and multi-unit properties.
FHA financing may stand out if your biggest obstacles are saving for a down payment or meeting conventional credit requirements.
The better fit depends on your finances, the property and your homeownership goals. Our guide to FHA vs. conventional loans can help you compare the two options and understand what may work for your situation.
What if the property has five or more units?
This is where the terminology gets a little confusing.
A property with five or more units doesn't qualify for the standard FHA home loan we're discussing here. HUD has separate FHA-insured multifamily programs for larger rental properties, and those programs work more like commercial real estate financing.
How To Buy A Multifamily Home With An FHA Loan
The process isn't dramatically different from buying another home, but there are a few extra numbers to watch.
Find out what you may qualify for. Review your credit, income, debts and available savings with a lender that offers FHA loans.
Set a comfortable homebuying budget. Remember to account for your down payment, closing costs and, for a three- or four-unit property, required reserves. Estimate your monthly FHA loan payment.
Search for a two- to four-unit property. Look for a home where you'd be comfortable living in one unit while renting out the others.
Talk through the rental income. Ask how the property's expected rent could affect your qualification.
For a triplex or fourplex, keep the self-sufficiency test in mind. The appraisal will ultimately determine the fair-market rents used for the FHA calculation.
Complete the FHA appraisal and underwriting. Your lender will review both your finances and the property to make sure the loan meets FHA guidelines.
Close and move into your unit. Once the loan closes, you can settle into your home and begin managing the other units as rentals.
Is an FHA multifamily loan right for you?
An FHA loan can open an interesting path to homeownership.
The low minimum down payment can make getting started more achievable, while eligible rental income may help make the monthly payment easier to manage. But you'll also need to be comfortable becoming a landlord, paying FHA mortgage insurance and meeting the extra rules that come with three- and four-unit properties.
You don't need to figure out every FHA guideline before you start looking. Understanding your budget and loan options first can give you a clearer idea of which multifamily homes make sense for you.
If owning a multi-unit home feels like it could fit your goals, you can check your eligibility and see what your next step toward homeownership could look like.
