For House Hackers
House Hacking: The Financing Part Nobody Explains
House hacking sounds complicated. The basic idea isn't — buy a property you're willing to live in, and let part of it help pay your mortgage. The interesting part is the financing.
Because you're actually going to occupy the property, you may have access to financing that looks very different from what an investor buying the exact same building would get. That's the whole game: the same duplex or fourplex can qualify completely differently depending on whether you're moving into one of the units.
Why occupying changes everything
An investor buying a 2-4 unit property as a pure rental faces investor-level down payments and investor-level rates. Someone buying the same building and living in one unit qualifies as an owner-occupant instead — which opens up financing built for buying a home, not for buying a rental portfolio.
Option 1
FHA
- Down PaymentAs low as 3.5%
- Best WhenYou want the lowest possible down payment and can meet FHA's property condition standards
- Watch ForMortgage insurance for the life of the loan in most cases. 3-4 unit purchases also have to pass FHA's self-sufficiency test — the net rental income from the other units has to cover the mortgage payment on its own.
Option 2
Conventional
- Down PaymentTypically 5% for owner-occupied 2-4 units
- Best WhenYou have stronger credit and want more flexibility than FHA allows
- Watch ForMortgage insurance if you're under 20% down — can run a bit higher than FHA's, though it can be removed later
Option 3
VA
- Down Payment0% down for eligible veterans and service members
- Best WhenYou qualify for VA benefits — this is usually the strongest option available
- Watch ForEligibility and entitlement rules, which are worth reviewing early
Does rental income actually count?
Yes, in most cases. Projected or existing rental income from the other units can count toward qualifying — often what makes a house hack pencil out when it wouldn't on your income alone. How much counts, and how it's documented, depends on the loan program and whether the property already has tenants in place. This is usually the single biggest factor in whether a house hack works on paper, so it's worth running the real numbers before you fall in love with a property.
Will the deal actually pencil?
This is the question that matters more than the loan type — and honestly, it's the thing my house hackers worry about most, for good reason. A house hack that looks great on a listing can still cost more out of pocket than you expect once real numbers — taxes, insurance, vacancy, the actual rent the other units will command — are run against it. Don't estimate this from the listing. Review the actual underwriting numbers before you write an offer, not after you're already under contract. That's exactly what I help you do.
A Real Deal
2-Unit Purchase, St. Petersburg
Buyers purchased a 2-unit property with 3.5% down. We structured 6% in seller credits to buy down the rate and cover closing costs entirely — so they walked in with no closing costs. After accounting for the rent from the other unit, their net housing cost came out to $973 a month.
If you want the lowest possible down payment — FHA is usually the starting point, as long as you can work with the property condition requirements.
If you have stronger credit and want more flexibility — conventional financing may cost less over time, even with a slightly higher down payment.
If you're a veteran or eligible service member — VA financing is almost always the strongest option on the table.

Common Questions
How much down payment do I need to house hack a multifamily property?
House hacking a 2-4 unit property can qualify for owner-occupant financing with a meaningfully lower down payment than a standard investment property loan, since you're living in one unit while renting the others.
Can I use rental income to help me qualify for a house hack?
Yes, in most cases. Projected or existing rental income from the other units can count toward qualifying — often what makes a house hack pencil out when it wouldn't on your income alone. How much counts depends on the loan program and whether the property already has tenants.
What loan programs can I use to house hack a 2-4 unit property?
FHA and conventional financing are the most common paths, and VA financing is available with no down payment for eligible veterans and service members. Each has different down payment minimums and different rules for how rental income gets counted.
Can rental income help me qualify for a bigger loan, not just meet minimum requirements?
Yes. Rental income that counts toward qualifying can increase your total qualifying income, which can raise your maximum purchase price — not just help you afford a property you already picked out.
What is the FHA self-sufficiency test for a 3-4 unit house hack?
For FHA financing on a 3-4 unit property, the net rental income from the other units has to be enough to cover the entire mortgage payment on its own. This only applies to 3-4 unit purchases — not 2-unit properties.
