Key Takeaway: House hacking uses FHA financing (3.5% down) to buy multifamily, live in one unit, have tenant cover your mortgage. Build $12K-$15K in annual equity while paying zero housing costs.
House Hacking: The Math That Works
House hacking lets you buy a multifamily property with just 3.5% down (FHA financing), live in one unit, and have tenants pay your entire mortgage. You build wealth while living for free.
The simple framework:
- Buy duplex/triplex/fourplex with 3.5% down (FHA)
- Live in one unit
- Rent out remaining units
- Tenants' rent covers your mortgage
- You build equity while living rent-free
Duplex Example: $300,000 Property
| Component | Amount |
|---|---|
| Purchase Price | $300,000 |
| FHA Down Payment (3.5%) | $10,500 |
| Total Mortgage | $289,500 |
| Monthly Mortgage (PITI) | $2,000 |
| Tenant Rent (Unit 2) | $1,500 |
| Your Housing Cost | $500/month |
| Monthly Savings | $700/month vs renting |
| Annual Equity Build | $12,000+ (principal paydown) |
The result: You live for $500/month instead of $1,200/month renting, PLUS you build $12,000+ in equity annually.
Why House Hacking Works
| Advantage | Traditional Renting | House Hacking |
|---|---|---|
| Down Payment | N/A (rent only) | 3.5% FHA |
| Monthly Housing Cost | $1,200 rent | $500/month share |
| Equity Building | $0/month | $500+/month |
| 10-Year Outcome | $144,000 spent | $60,000 + $60K+ equity |
Key benefits:
- Low entry cost: 3.5% down vs 20% traditional
- Leverage: Tenants pay principal = your equity
- Learning: Live in property, see operations firsthand
- Savings: Cut housing costs by 50%+ immediately
Three House Hacking Levels
| Property | Price | Down | Your Cost | Rental Income | Net Cash Flow |
|---|---|---|---|---|---|
| Duplex | $300K | $10.5K | $500/mo | $1,500 | $500/mo savings |
| Triplex | $400K | $14K | $200/mo | $3,000 | $1,200/mo savings |
| Fourplex | $480K | $16.8K | -$100/mo | $4,175 | $323/mo profit |
As you increase units, your housing cost decreases. At the fourplex level, the property covers your housing AND generates profit.
Fourplex Financial Example
$480,000 fourplex with FHA financing:
Monthly Income: $4,175
- Unit 2: $1,350
- Unit 3: $1,400
- Unit 4: $1,425
Monthly Expenses: $3,852
- Mortgage: $3,100
- Property management (8%): $334
- Maintenance & vacancy reserves: $418
Monthly Result: +$323 profit Annual Result: +$3,876 + equity building
The owner lives for FREE and makes $323/month.
FHA House Hacking Rules
Occupancy requirement: You must live in one unit as your primary residence for at least 1 year. Move in within 60 days of closing.
Self-sufficiency test (3-4 units): FHA uses 75% of expected rental income in debt-to-income calculations. Property must be able to support itself mathematically.
Reserve requirement (3-4 units): You need 3 months of PITI in savings after closing. Example: $3,100/month PITI = $9,300 required in reserves.
FHA Eligibility: Properties must meet FHA appraisal standards and you must occupy one unit as your primary residence for at least one year.
These rules ensure you buy sustainable properties and have financial cushion for vacancies.
The Comparison: House Hacking vs Renting for 10 Years
| Metric | Renting | House Hacking |
|---|---|---|
| Monthly Cost | $1,200 | $500 |
| 10-Year Spend | $144,000 | $60,000 |
| Equity Built | $0 | $60,000+ |
| Appreciation Gain | N/A | $30,000–$50,000 |
| Total Net Worth | -$144,000 | +$90,000–$110,000 |
House hacking turns your housing expense into an investment.
