How to Get Started with House Hacking

Step 1
Choose Your Property Type

Duplex, triplex, fourplex, or single-family with rentable bedrooms. Multi-family often works best for beginners.

Step 2
Calculate Your Numbers

Use this calculator to ensure rental income will cover most or all of your housing costs.

Step 3
Secure Financing

FHA loans allow as little as 3.5% down on 2-4 unit properties if you live in one unit.

Step 4
Screen Tenants Carefully

Living near your tenants means quality screening is crucial for a positive experience.

Rent spare rooms on Airbnb or VRBO while living in the property.
