House Hacking

Last reviewed July 15, 2026

House hacking means living in one unit of a property while renting the rest, using low-down-payment owner-occupant loans to start investing.

What is house hacking?

House hacking is buying a property with an owner-occupant loan, living in part of it, and renting out the rest, other units of a duplex-to-fourplex, spare bedrooms, or a basement suite/ADU. The tenants’ rent offsets most or all of the housing payment, converting a household’s largest expense into an investment engine.

The financial edge comes from owner-occupant financing. Primary-residence loans require as little as 3% to 5% down (3.5% FHA) versus 20% to 25% for investment properties, and carry lower rates. On a multifamily purchase, lenders even count a portion of expected rent toward qualification. The standard requirement is living in the property for at least one year, after which many house hackers move to the next property, repeat the low-down-payment purchase, and keep the previous one as a full rental.

The costs are lifestyle-based: living beside your tenants, sharing walls or common spaces, and being the landlord where you sleep. The tax picture is a hybrid, the rented portion generates rental income, deductions, and depreciation, while the owner-occupied share of gain can qualify for the Section 121 exclusion at sale. For most beginners with limited capital, house hacking is the cheapest and most forgiving entry into real estate investing.

Worked example

You buy a $400,000 duplex with 5% down ($20,000) on an owner-occupant loan. Your PITI plus PMI is about $2,900 per month. The other unit rents for $1,750, cutting your housing cost to roughly $1,150, less than the $1,700 apartment you left, while tenants pay down your mortgage and you gain landlord experience with minimal risk.

Frequently asked questions

How long do I have to live in a house hack?: Owner-occupant loans generally require you to move in within 60 days and live there for at least one year, the commitment you sign at closing. After the year, you can move out, rent your unit, and buy the next primary residence with another low-down-payment loan. Misrepresenting occupancy intent is mortgage fraud, so take the one-year commitment seriously and document your occupancy.
Can I house hack a single-family home?: Yes, renting spare bedrooms is the simplest version, and homes with basement apartments or ADUs work even better since you keep separate living space. Room rentals typically yield $500 to $1,000+ per room in most metros. The financing advantage is identical (it is your primary residence either way); the trade-off is sharing your actual living space rather than just a building.
