House hacking is the cheapest entry point into real estate investing, and the reason is financing rather than strategy. Because you live in the property, it qualifies as owner-occupied — which means down payments measured in single digits rather than twenty-five percent, and rates a full point or more below investor pricing. That gap is the entire advantage, and understanding when it closes is the important part.
The forms it takes
Buy a duplex, triplex or fourplex, live in one unit and rent the rest. Buy a single-family house and rent the spare bedrooms. Rent a finished basement or a legal accessory dwelling unit. Buy a house with a detached garage apartment. The structure varies; the financing logic does not — you occupy one part, so the whole thing is an owner-occupied purchase.
The financing advantage in numbers
An owner-occupied FHA purchase of a fourplex can require as little as 3.5% down. VA can be zero down for eligible borrowers. Conventional owner-occupied multifamily typically starts around 5%. The investor version of the same building requires 20–25% down at a rate commonly 0.75–1.5 points higher. On a $600,000 fourplex that is roughly $21,000 down instead of $150,000 — the difference between starting now and starting in four years.
Rental income can help you qualify
Lenders will typically count a portion of projected rent from the units you are not occupying toward qualifying income — commonly around 75%, the haircut covering vacancy and management. On a fourplex where three units rent for $1,400 each, that is roughly $3,150 a month of qualifying income, which frequently lifts a buyer into a property they could not otherwise afford on salary alone.
The occupancy requirement is a real obligation
Owner-occupancy financing carries a certification that you will occupy the property, typically for at least twelve months. It is not a formality. Signing that certification while intending to rent the whole building is mortgage fraud, and the penalties are not theoretical. If you want the property as a pure rental, buy it as one. The honest sequence is: occupy for the required period, then convert.
The exit, and where DSCR takes over
After the occupancy period, most house hackers move out, rent the remaining unit, and repeat. The original loan usually stays in place — moving out after satisfying the occupancy term does not breach anything. The second property is where the calculus changes: you can house hack again with owner-occupied financing, or buy a pure rental, at which point DSCR financing becomes the route because it qualifies on the property’s rent rather than your income and imposes no portfolio limit. Many investors run two or three house hacks and then switch entirely.
House Hacking FAQ
As little as 3.5% with FHA, zero with VA for eligible borrowers, and around 5% on conventional owner-occupied — against 20–25% for the same building bought as an investment.
Typically at least twelve months under the occupancy certification. Confirm the exact requirement for your loan programme.
Usually a portion of it — often around 75% of projected rent from the units you do not occupy, with the haircut covering vacancy and management.
Yes. Many investors do it repeatedly, moving into a new property each time, though lenders scrutinise repeated owner-occupied purchases and FHA limits how many loans you can hold at once.
The loan generally stays in place once the occupancy period is satisfied, and the property becomes a full rental. Notify your insurer, since a homeowner policy needs to become a landlord policy.
The comparison that matters is against renting, not against a past rate. If tenant rent covers most of the payment, your housing cost falls regardless of the rate environment.
