Housing is the single largest line item in the average person's budget, consuming 30% to 50% of take-home pay. House hacking is the proven strategy of purchasing a small multifamily property (2 to 4 units), living in one unit, and renting out the remaining units to cover your mortgage payment.
The Financial Mechanics of a Duplex Hack
Consider a $550,000 duplex purchased with an FHA 3.5% down payment:
- Down Payment (3.5%): $19,250
- Total Monthly PITI Mortgage + PMI: $3,650/month
- Rental Income from Unit B: $2,200/month
- Net Out-of-Pocket Housing Cost: $1,450/month (vs $2,400 for a comparable 1-bedroom rental).
Key Benefits Beyond Free Housing
- Principal Paydown: Your tenants pay off your loan principal every month, building hundreds of thousands in equity.
- Depreciation Tax Shield: Deduct depreciation against rental income, drastically reducing taxable gains.
- Appreciation & Refinancing: Once equity exceeds 20%, eliminate FHA mortgage insurance or take cash out for property #2.
