House Hacking: Live (Almost) Free and Start Investing With One Purchase

House hacking is the lowest-barrier entry into real estate investing: buy a property, live in part of it, and let tenants pay most of your housing cost. It works because you get investor economics with homeowner financing.

The core move

Buy a 2–4 unit property (or a home with rentable rooms or an ADU) using an owner-occupied loan — FHA from 3.5% down or conventional from as little as 3–5% — instead of the 15–25% down an investment loan requires. Live in one unit, rent the rest, and let the rent cover most or all of the mortgage.

The math that makes it work

On a duplex where the other unit rents for $1,600, you're effectively paying a fraction of the full payment to live there — while building equity in the entire property and learning landlording with the shortest possible commute to your rental.

What nobody tells you

• You live next to your tenants: screening matters double when the late-rent conversation happens across a shared porch.
• Occupancy rules are real: owner-occupied loans typically require living there at least a year — misrepresenting is fraud.
• Lenders often count a portion of expected rent toward qualifying, stretching what you can buy.
• The exit is elegant: after the occupancy period, move out, rent your unit, and repeat with a new owner-occupied purchase.

Your first rental doesn't have to be a separate purchase. It can be the other side of your own wall.
