House Hacking Guide
What is House Hacking?
House hacking means buying a multi-unit property (duplex, triplex, or fourplex), living in one unit, and renting out the others. The rental income offsets your mortgage, reducing or eliminating your housing cost.
Why House Hack?
- Live for free (or close to it) - Tenants pay your mortgage
- Low down payment - FHA loans allow 3.5% down on 2-4 units
- Build wealth - Gain equity while saving on housing costs
- Learn landlording - Start small with tenants next door
- House hack again - Move out after a year, rent your unit, repeat
FHA Self-Sufficiency Test (3-4 Units)
For 3-4 unit properties, FHA requires the property to be "self-sufficient": 75% of the total rental income (including your unit) must exceed the mortgage payment (PITI). This calculator shows if you pass.
Typical House Hack Scenarios
- Duplex: Live in one, rent one. Often reduces housing cost 50%+
- Triplex: Live in one, rent two. Often live for free or positive cash flow
- Fourplex: Live in one, rent three. Best cash flow potential
Tips for Success
- Buy in areas with strong rental demand
- House hack for at least 1 year (FHA requirement)
- Screen tenants carefully - they're your neighbors
- Set aside reserves for vacancies and repairs
- Consider moving out after a year and renting all units
