How To Use
See if house hacking can eliminate your housing cost
🚀 Getting Started
1
Enter Property Info
Price, down payment, rate, number of units, and average rent per unit.
2
Add Operating Costs
Taxes, insurance, utilities, maintenance, and vacancy reserve.
3
See Your Offset
What % of your mortgage + expenses the rental units cover. 100%+ = you live for free.
4
Plan the Move-Out
See what cash flow looks like when you eventually move out and rent ALL units.
📊 Terms Made Simple
House Hacking: Buying a 2-4 unit property, living in one unit, and renting the others. FHA loans allow as low as 3.5% down on owner-occupied properties up to 4 units.
Mortgage Offset: The percentage of your total housing cost (PITI + expenses) covered by rental income. 100% = tenants pay your entire mortgage. Over 100% = you profit while living there.
PITI: Principal + Interest + Taxes + Insurance. This is your full monthly housing payment — the number that matters, not just the mortgage amount.
FHA Multi-Family: FHA allows 3.5% down on 2-4 unit properties if you live in one unit. This is the most powerful first-time investor hack — traditional investment loans require 20-25% down.
