The reason house hacking works is the financing. Because you are going to live in the property, you qualify for owner-occupied loans with down payments a fraction of what investors pay, which is how many people invest in real estate with $10k or so instead of a six-figure down payment. Here are the loan options that matter for house hackers, with the details verified against current 2026 lending rules.
Quick note before we start. Loan programs, limits, and rates change, and your eligibility depends on your credit, income, and market. Use this as a map, then confirm the specifics with a lender who invests themselves.
Conventional: As Little as 5% Down on 2-4 Units
This is the change that made house hacking dramatically better. As of late 2023, Fannie Mae allows owner-occupants to buy two, three, and four unit properties with as little as 5 percent down, and that program is still in effect in 2026. Historically the minimum on multifamily was 15 to 25 percent, so this is a massive shift for house hackers. It applies to standard purchases, no-cash-out refinances, and the HomeReady and HomeStyle Renovation loans.
Conventional has real advantages beyond the low down payment. There is no income limit (you could earn a very high income and still use 5 percent down on a fourplex), there is no self-sufficiency test, and on a single-family a first-time buyer can go as low as 3 percent down. Plan on keeping about six months of mortgage payments in reserve. One tradeoff: if you put less than 20 percent down, you will pay private mortgage insurance until you reach enough equity.
FHA: 3.5% Down, With One Catch on Triplexes and Fourplexes
FHA lets you buy a one-to-four unit property with 3.5 percent down and more forgiving credit requirements. The catch shows up on three and four unit properties, where FHA applies a self-sufficiency test: 75 percent of the property's total market rent (a 25 percent haircut for vacancy and management) must fully cover your mortgage payment including taxes and insurance. Duplexes are exempt from this test.
Here is the test in numbers. Say a fourplex rents for $1,000 per unit, so $4,000 total. Seventy-five percent of that is $3,000. If your total payment is $2,900, you pass. If it is $3,100, you fail. In 2026, with higher rates and prices, this test is harder to pass, which is exactly why the conventional 5 percent down option (no self-sufficiency test) has become so valuable for triplexes and fourplexes. If you are still deciding between a duplex and a bigger property, why 2-to-4-unit properties are the sweet spot walks through the tradeoffs.
The FHA 203K: Buy and Renovate in One Loan
If the house hack needs work, the FHA 203K renovation loan lets you finance the purchase and the rehab together, as an owner-occupant. I know an investor who bought two duplexes this way as a single woman on a modest income, one with a light "streamlined" 203K and one taken down to the studs with a full 203K.
A few things to know. The 203K requires a HUD-approved cost consultant (budget around $1,000 for that report) and a licensed general contractor, so no doing the work yourself. The streamlined version covers cosmetic work up to about $35,000; the full version handles structural projects. These loans take longer to close, so plan for roughly 75 days, and the property has to appraise both as-is and after-repair. A powerful newer twist: on many 203K loans you can now add a unit like an ADU or mother-in-law suite and use its projected rent to help you qualify. The government finances the new rental unit and counts the future income. It is only available to owner-occupants, which is a big reason to add units while you live there. Before you commit to that route, running the numbers on an ADU will tell you whether the build actually pencils.
VA: Zero Down, Up to Four Units
If you are eligible, the VA loan is the best financing available. Zero down, up to four units, no income limit, no loan limit, no monthly mortgage insurance, and no self-sufficiency test. There is a one-time funding fee, but it is waived entirely for veterans with a service-connected disability. For a house hacker who qualifies, nothing else comes close.
Down Payment Assistance
Do not overlook down payment assistance. Many states offer a "silent second" loan that covers 3 to 5 percent of the down payment with no interest and no monthly payment, repaid only when you sell or refinance. Some FHA-paired programs cover the entire 3.5 percent down. These come with income limits that vary by program and area, so ask your lender what your state offers.
A $500,000 House Hack, Three Ways
Let me make this concrete with a duplex priced at $500,000, where you live in one side and rent the other. Here is how the same purchase looks under each loan, using a 6.5 percent 30-year rate (roughly where rates sit in mid-2026), about 1.25 percent property taxes, plus insurance and mortgage insurance where it applies. These are illustrative numbers to show the shape of the deal, not a quote. Yours will vary by market and lender.
| Loan | Down payment | Loan amount | Est. monthly payment (taxes, insurance, and mortgage insurance included) |
|---|---|---|---|
| Conventional, 5% down | $25,000 | $475,000 | about $3,825 |
| FHA, 3.5% down | $17,500 | $482,500 | about $3,900 |
| VA, 0% down | $0 | $500,000 | about $3,785 |
Now add the rent. Say the other side of the duplex rents for $2,200 a month. While you live there on the conventional loan, your real housing cost drops from about $3,825 to roughly $1,625 a month. You are living in a $500,000 asset for less than it would cost to rent a comparable place, and you are building equity and getting the tax benefits of ownership while you do it.
Then comes the powerful part. After you satisfy the one-year occupancy and move out, you rent both sides for about $4,400. Against a roughly $3,825 payment, the property is around breakeven to modestly positive once you set aside for vacancy and maintenance, and it only improves from there as rents rise and, on the conventional loan, your private mortgage insurance falls off once you reach 20 percent equity. FHA mortgage insurance typically stays for the life of the loan, so many house hackers refinance out of FHA into a conventional loan later, or pull equity with a HELOC once they have it.
A couple of things shift the math further in your favor. In a lower-cost market, that same $500,000 might buy a fourplex instead of a duplex, so three rented units could cover almost your entire payment while you live in the fourth (just remember the FHA self-sufficiency test on three and four unit properties, which is why many buyers use the conventional 5 percent down option there). And if you are house hacking a single-family home, renting two spare rooms at $800 each still knocks $1,600 off your payment.
Two Rules Every House Hacker Should Know
The owner-occupancy commitment is about intent. When you take one of these loans, you sign a statement that you intend to live in the property for the next 12 months. If life changes and you sell before then, that is generally fine. The problem is buying with owner-occupied financing and quickly renting it out instead of living there. Fulfill the year, then move on to the next one.
Use your own commission if you are a licensed agent. If you are the buyer and a licensed agent, you can often earn the commission on your own purchase, which effectively slashes your out-of-pocket. You cannot apply the commission as the down payment on the closing statement (the cash has to be in your account), but you get it back at closing, which lowers your true cost significantly.
Once you know which loan fits, the next step is running the deal and repeating the process.

FAQ
Q: What is the lowest down payment for a multifamily house hack? A: For owner-occupants, conventional financing now allows as little as 5 percent down on two-to-four unit properties, FHA allows 3.5 percent down, and VA allows zero down for eligible veterans. Down payment assistance programs can lower your cash further.
Q: What is the FHA self-sufficiency test? A: On three and four unit FHA purchases, 75 percent of the property's total market rent must fully cover the mortgage payment including taxes and insurance. Duplexes are exempt. It is harder to pass in a high-rate environment, which is why the conventional 5 percent down option is often better for larger multifamily.
Q: Can I finance renovations into a house hack loan? A: Yes. The FHA 203K renovation loan lets owner-occupants finance the purchase and the rehab in one loan. It requires a HUD-approved cost consultant and a licensed contractor, and on many 203K loans you can now add an ADU and use its projected rent to help qualify.
