An FHA loan can't buy a pure investment property, but it can buy a two-to-four-unit home you live in while renting the other units. I'll cover what FHA actually allows, the loan limits and costs for small multifamily, the self-sufficiency test many triplex and fourplex buyers miss, and the math that decides whether it works.
Here's the direct answer before the nuance: an FHA loan cannot buy a property you plan to rent out and never live in. FHA financing is built for primary residences, and the program says so plainly. At least one borrower has to move into the home within 60 days of closing and intend to live there for at least a year.
So where does the idea of an FHA investment property come from? From one sanctioned strategy and a few after-the-fact exceptions. You can buy a building of two to four units with an FHA loan, live in one unit, and rent out the rest. The rent those other units produce is the investment piece, and it's the path I'll focus on, because it works and it's what most people are actually asking about.
What you cannot do is treat owner-occupancy as a formality. The FHA rulebook is explicit that it will not insure a loan when the transaction was designed to use FHA mortgage insurance as a way to acquire an investment property, even if that property would be the only one you own with FHA financing. Signing an occupancy certification you don't intend to honor isn't a gray area. It's mortgage fraud, and it carries real consequences. The honest version of the strategy works well on its own, so there's no reason to reach for the dishonest one.
The strategy has a nickname, 'house hacking,' and the mechanics are simple. You buy a two-, three-, or four-unit building, occupy one of the units as your primary residence, and rent the others. The FHA treats anything up to four units as residential property, so a duplex, triplex, or fourplex qualifies for the same low-down-payment financing as a single-family home, as long as you live there.
Two features make this work in your favor. The first is the down payment. With a credit score of 580 or higher, you can put down 3.5% of the purchase price. Borrowers in the 500 to 579 range can still qualify, but the down payment rises to 10%. Either way, you're financing an income-producing building with far less cash upfront than a conventional, non-owner-occupied investment loan typically requires.
The second is the loan limit. FHA caps are noticeably higher for multi-unit properties than for single-family homes, which is the quiet advantage most first-time investors overlook. The floor, the smallest limit anywhere in the country, currently runs to $693,050 for a two-unit property, $837,700 for three units, and $1,041,125 for four units. In higher-cost metros those caps climb steeply, reaching as high as $1,599,375, $1,933,200, and $2,402,625 for two-, three-, and four-unit buildings respectively. The single-family floor, by contrast, sits at $541,287. The extra borrowing room is the whole point. It lets an owner-occupant reach small multifamily buildings that would otherwise sit out of range.
The occupancy rule is the cost of admission, and it's firm. At least one borrower moves in within 60 days of closing and lives there as a primary residence for at least a year. You can rent rooms in your own unit from day one, and you can rent the other units immediately, since you were never expected to occupy those. When a borrower comes to AmeriSave looking at a two-to-four-unit purchase, confirming the property is genuinely owner-occupied and the unit count is right is the first thing we check, because everything else in the file depends on it.
Strategy is easy to describe and easy to romanticize, so let me put real figures on it. Assume a $400,000 duplex and a borrower who qualifies for the 3.5% down payment. I'll use a 6.5% fixed rate for the arithmetic; your actual rate will depend on the market and your credit.
Start with the cash to buy. The down payment is 3.5% of $400,000, or $14,000, which leaves a base loan of $386,000. FHA also charges an upfront mortgage insurance premium of 1.75% of that base loan, about $6,755, and most borrowers roll it into the balance rather than pay it at closing. That brings the financed amount to roughly $392,755.
Now the monthly payment. Principal and interest on about $392,755 at 6.5% over 30 years runs near $2,483. FHA's annual mortgage insurance premium is 0.55% of the balance for most borrowers, which adds about $180 a month. Property taxes and homeowners insurance vary widely by location, but $500 a month is a reasonable placeholder for a building this size. Add those together and the full monthly payment lands around $3,163.
Here's where the second unit changes the picture. Say it rents at $1,800 a month. For qualifying, the FHA lets the lender count 75% of the appraiser's fair-market rent, $1,350 here, and apply it against your income, which makes the loan easier to approve. In real life you collect the whole $1,800. Subtract that from the $3,163 payment and your out-of-pocket housing cost falls to about $1,363 a month: a building you own, with a tenant helping cover well over half the payment.
The 75% figure isn't arbitrary, and it isn't a fee. It's a vacancy-and-maintenance cushion. The FHA assumes a unit won't be occupied every single month and that upkeep costs money, so it counts three-quarters of market rent toward qualifying rather than the full amount. Plan your budget around the conservative number, then enjoy the difference when the unit stays rented.
Duplexes are straightforward. Three- and four-unit buildings come with an extra test that surprises a lot of buyers, and it's worth understanding before you make an offer, because it can sink an otherwise sensible deal.
The FHA calls it the self-sufficiency test, and the logic behind it is sound. On a three- or four-unit property, the building's own rent has to be able to carry the full mortgage payment, whether or not you keep your day job. The agency wants the property to stand on its own.
The formula has a specific shape. A lender takes the appraiser's estimate of fair-market rent for every unit in the building, including the one you'll live in, and then subtracts the larger of the appraiser's vacancy-and-maintenance figure or 25% of total rent. What's left is the net self-sufficiency rental income. That number has to be equal to or greater than your full monthly payment of principal, interest, taxes, insurance, and mortgage insurance. Put plainly, three-quarters of the building's market rent must cover the entire payment.
A worked example makes it concrete. Picture a fourplex where the appraiser sets fair-market rent at $4,000 a month across all four units. Take 75% of that and you get $3,000. If your full monthly payment comes to $2,900, the property passes, because $3,000 covers $2,900 with room to spare. If the payment instead came to $3,200, the property fails the test, and the FHA would not insure the loan at that amount.
When a property falls short, you still have moves. A larger down payment lowers the loan and the payment, which can pull you back under the line. So can a lower rate, whether through stronger credit or paying points. And a conventional loan skips the self-sufficiency test entirely, which is sometimes the cleaner answer for a three- or four-unit purchase. At AmeriSave we run this calculation early, using real rents, taxes, and insurance rather than optimistic guesses, so a borrower knows before writing an offer whether a triplex or fourplex will actually clear the bar.
One more requirement rides along with three- and four-unit purchases: cash reserves. After closing, you need to document reserves equal to three months of the full payment. It's a backstop in case a unit sits empty for a stretch, and it's easy to forget when you're focused on the down payment. Build it into your plan from the start. Duplexes, worth repeating, are exempt from both the self-sufficiency test and this reserve requirement, which is one reason a two-unit building is the most forgiving way into the strategy.
Every loan choice is a trade between what you pay now and what you pay over time, and the small-multifamily decision is a clean example of it. Two questions cut through most of the noise: how often does a cost land, and how big is it when it does. FHA wins decisively on the up-front question and loses ground on the recurring one. Knowing which matters more for your situation is the whole decision.
The up-front advantage is real. A 3.5% down payment on a four-unit building is a far smaller barrier than the larger amounts a conventional investor loan asks for, and for many buyers it's the only way the deal happens at all. That low entry cost is FHA's reason to exist.
The recurring cost is the mortgage insurance premium, and the structure matters more than the rate. If you put less than 10% down, the annual premium stays on the loan for its entire life. It does not fall off when you cross 20% equity the way private mortgage insurance does on a conventional loan. Put 10% or more down and the premium drops off after 11 years. On the duplex example above, that 0.55% premium is roughly $2,160 a year, every year, for as long as the FHA loan is in place. Over a decade that's more than $20,000. The number is not catastrophic, but it's real money, and it's the cost most house-hacking conversations skip.
There's a clean exit, though, and it's the reason the long-run cost worries me less than it might. Once you've built about 20% equity, through payments, appreciation, or both, you can refinance into a conventional loan and shed the FHA mortgage insurance entirely. A conventional loan with 20% equity carries no monthly mortgage insurance at all. The FHA loan gets you in the door cheaply; a refinance later trims the carrying cost once you have equity to work with.
It's also worth knowing the alternative on the way in. Fannie Mae now allows an owner-occupied two-to-four-unit purchase with as little as 5% down on a conventional loan, where the old standard was higher. That's a larger down payment than FHA's 3.5%, but it comes with cancellable mortgage insurance and no self-sufficiency test on three- and four-unit buildings. For a borrower with stronger credit and a bit more cash, it can be the better long-run structure. At AmeriSave we'll run both side by side, because the right answer depends on your credit, your cash, and how long you plan to hold the building, not on which program sounds better in the abstract.
Once you've satisfied the one-year occupancy requirement, the strategy opens up. Here's what's possible and what still has rules.
After a year of living in the home, you can move out and rent it in full. You don't have to sell it, and you don't have to refinance it. The FHA loan stays in place at its original terms, and the occupancy obligation is considered met. This is how a lot of long-term rental portfolios start: buy a duplex, live in it a year, move on to the next one, and keep the first as a rental. Repeat that a few times and the early purchases quietly become an income base.
The FHA generally insures only one loan per borrower at a time, precisely so the program isn't used as a back door into a rental empire. There are four exceptions where you can hold a second FHA loan without selling the first. The first is relocation: you move for work to a home more than 100 miles from your current one. The second is a documented increase in family size that makes your current home too small. The third covers leaving a jointly owned home that a co-borrower will keep occupying, which often applies after a divorce. The fourth applies if you were a non-occupying co-borrower on someone else's FHA loan and now want one for your own primary residence.
The 100-mile relocation case is the most common, and it carries a useful wrinkle. When the move clears 100 miles and you document a market-rate lease, the rent from the home you're leaving can count toward qualifying for the new loan. Inside 100 miles, that rental income generally won't count unless you can show at least 25% equity in the departing home, so plan around both mortgage payments if the move is local.
Refinancing is the other lever. AmeriSave offers the FHA Streamline refinance, which lets you move into a lower rate with limited paperwork and, in many cases, no new appraisal, as long as the refinance produces a real benefit. A cash-out refinance is also available, though it keeps the owner-occupancy requirement, so it's a tool for the home you live in, not a vacated rental.
This is where a strategy I lean on fits cleanly: lock now, refinance later. When the right building shows up at a price you've negotiated well, take the rate that's available and move forward. You can't re-negotiate the purchase price after the deal closes, but you can almost always refinance the rate when the market gives you a better one. Focus on price first, then rate. A good price is permanent; a rate is temporary.
Start with your timeline, because it drives everything else. Are you buying something you'll live in for a year and then keep as a rental, or a building you intend to hold and occupy for the long haul? The answer shapes whether the FHA route or a conventional one serves you better, and it's a more useful first question than what's the rate.
A few honest filters. FHA's owner-occupied multifamily path fits best when your savings are limited, your credit is in the 580-and-up range, and you're comfortable living on-site for at least a year. It fits poorly if you want a hands-off, never-occupied rental from day one. That's simply not what the program is for, and a conventional investment loan is the right tool there.
The deeper principle is one I come back to often: meaningful financial outcomes come from a handful of good decisions made for the right reasons, not from constant activity. Buying a small multifamily building you live in, financed cheaply, with a tenant helping cover the payment, can be one of those decisions. It's worth doing carefully and slowly rather than forcing a property that doesn't pass the math.
If you're weighing a two-to-four-unit purchase, the most valuable thing you can do is run the actual numbers, the payment, the rent, and the self-sufficiency test where it applies, before you fall for a building. Getting a fully underwritten preapproval before you shop, which AmeriSave calls Certified Approval, gives you a stronger position when you make an offer. A loan officer at AmeriSave can run that math with you so the decision rests on figures rather than hope.

No, not as a standalone rental you won't live in. The FHA insures loans only for primary residences, and at least one borrower must move in within 60 days of closing and live there for a year. The workable version is a two-to-four-unit building: you occupy one unit and rent the others, which is the only FHA-sanctioned way to earn rental income on the property. The multi-unit loan limits help here, running from a floor of $693,050 on a duplex up to $1,041,125 on a fourplex, with far higher caps in expensive areas. Treating owner-occupancy as a paperwork formality is a serious mistake. The FHA explicitly refuses to insure loans designed to use its program to acquire investment property, and falsely certifying occupancy is mortgage fraud. Bought honestly, though, the live-in-one-unit approach is a legitimate and affordable way to start.
The short answer is 3.5% of the purchase price if your credit score is 580 or higher, and 10% if it falls between 500 and 579, the same minimums the FHA sets for a single-family home. The one caveat worth flagging: a low down payment means a larger loan, which raises both your payment and your mortgage insurance, so the cheapest entry isn't always the cheapest over time. Consider a $400,000 duplex. At 3.5% down you'd bring $14,000 to the table, leaving a $386,000 base loan before the financed upfront mortgage insurance premium. At 10% down on the same building you'd bring $40,000, carry a smaller balance, and pay less in interest and insurance every month. If you have the cash and want a lighter long-run cost, the larger down payment is often the smarter structure even when a smaller one is allowed.
It's an extra requirement the FHA applies to three- and four-unit properties to make sure the building can pay for itself. The lender takes the appraiser's fair-market rent for all units, including the one you'll occupy, then subtracts the larger of the appraiser's vacancy-and-maintenance estimate or 25% of total rent. The result, called net self-sufficiency rental income, must be equal to or greater than your full monthly payment of principal, interest, taxes, insurance, and mortgage insurance. In plain terms, three-quarters of the building's market rent has to cover the entire payment. So a fourplex with $4,000 in monthly market rent produces $3,000 in qualifying income, which clears a $2,900 payment but fails a $3,200 one. Duplexes are exempt. Three- and four-unit buyers also must document cash reserves equal to three months of the payment after closing, so budget for that alongside the down payment.
Picture a borrower who bought a duplex with an FHA loan, lived in it, and then took a job three states away. Can they keep that loan and get a second FHA loan for a new home? In that case, yes. The FHA normally limits you to one loan at a time, but it allows a second under four specific exceptions: relocating for work to a home more than 100 miles away; a documented increase in family size; vacating a jointly owned home that a co-borrower will keep occupying; or moving from non-occupying co-borrower on someone else's loan to owner of your own. The relocation exception is the one most people use. When the move clears 100 miles and you document a market-rate lease, the rent on the home you're leaving can also help you qualify for the new loan, which makes carrying both far more manageable.
Sometimes automatically, often only by refinancing. If you put down less than 10%, the FHA's annual mortgage insurance premium stays on the loan for its full life and does not cancel at 20% equity the way conventional private mortgage insurance does. The caveat that changes the math: put 10% or more down and the premium drops off after 11 years. For everyone else, the common exit is a refinance. Say you bought with 3.5% down and, after several years of payments and some appreciation, your home is worth enough that you hold about 20% equity. At that point you can refinance into a conventional loan, which carries no monthly mortgage insurance once you're at 20% equity. The upfront premium of 1.75% is generally not refundable after the first few years, so factor the ongoing 0.55% annual premium into your hold-versus-refinance decision.
For the units you'll rent, the FHA generally lets a lender count 75% of the appraiser's fair-market rent toward your qualifying income. The other 25% is held back as a cushion for vacancy and upkeep, since no unit stays rented every month and maintenance has a cost. On a unit that appraises at $1,800 in market rent, that means $1,350 counts toward helping you qualify, even though you collect the full $1,800 once a tenant is in place. Keep two ideas separate. This 75% qualifying calculation applies to the rental units and helps your debt-to-income ratio on any two-to-four-unit purchase. The self-sufficiency test is a different, additional hurdle that applies only to three- and four-unit buildings and looks at whether the whole building's rent covers the whole payment. A duplex uses the 75% qualifying rule but skips the self-sufficiency test entirely.
