Multi-family home financing: living in one unit, renting the others

September 8, 20262 min readHelloLend Team

A duplex, triplex or fourplex can qualify for the same favorable financing as a single-family home, as long as you live in one unit as your primary residence. Living in one unit while renting out the rest, sometimes called house hacking, is a meaningful advantage over financing an investment property outright.

How a house-hack purchase comes together

Choose the propertyDuplexes, triplexes and fourplexes, up to four units, can qualify for owner-occupied financing.
Live in one unitMaking one unit your primary residence keeps conventional, FHA and VA owner-occupied terms in play.
Document the rentA signed lease or a market rent appraisal shows the income from the other units.
Count the incomeA portion of the projected rent can often go toward qualifying income.
Hold reservesSome lenders want extra cash on hand in case a unit sits vacant.

Once you move out, a future refinance typically follows investment property rules.

How owner-occupied financing works

Properties with up to four units can qualify for conventional, FHA or VA owner-occupied financing, as long as the buyer lives in one unit
FHA and VA loans allow low or no down payment on these properties under the same rules as a single-family owner-occupied purchase
A portion of the projected rental income from the other units can often be counted toward qualifying income
Once you move out, the property typically converts to investment financing rules for any future refinance

What lenders look at differently

A signed lease or a market rent appraisal to document rental income from the units you don't occupy
Reserves, since some lenders require additional cash to cover the property if a unit sits vacant
Landlord experience, which usually isn't required for owner-occupied multi-family purchases, unlike pure investment property loans

A multi-family purchase can turn a mortgage payment into a partially, or fully, offset expense while still qualifying for owner-occupied rates and down payment requirements.

For buyers open to being a landlord, it's one of the more efficient ways to build equity and rental income from a single purchase.
