"You need 20% down or don't even bother."
That's what my uncle told me. He'd owned rentals for 30 years. I figured he knew what he was talking about.
But I only had $15,000 saved. In my market, 20% down meant I'd need $40,000 minimum. I was years away.
Then I learned about house hacking and low down payment options. FHA loans. Conventional loans with 5% down for first-time investors.
I ran the numbers. They worked. Here's how.
The Property
Duplex in a working-class neighborhood. Listed at $185,000.
Unit A: 2 bed/1 bath (I'd live here)
Unit B: 2 bed/1 bath (I'd rent this)
Market rent for Unit B: $1,100/month.
The Financing
I used a conventional loan with 5% down:
Purchase price: $180,000 (negotiated down)
Down payment: $9,000
Loan amount: $171,000
Interest rate: 6.5%
Monthly payment breakdown:
Principal & Interest: $1,081
Property taxes: $195
Insurance: $85
PMI: $142
Total: $1,503/month.
The Cash Flow Math
Income from Unit B: $1,100
My out-of-pocket: $1,503 - $1,100 = $403/month.
But wait — I was paying $850 in rent before. Now I'm paying $403 and building equity.
That's $447 in monthly savings plus equity paydown.
Not quite the "rental income" dream, but I was living for almost half my previous rent.
The Real ROI
Year one, I tracked everything:
Total out-of-pocket (mortgage minus rent collected): $4,836
Principal paydown: $2,280
Property appreciation: ~$5,000 (market went up)
Tax benefits: ~$1,800
Total return: $9,080 on a $9,000 down payment plus $5,000 closing costs.
That's a 65% return year one.
Where I Am Now
I moved out after a year. Rented Unit A for $1,150.
Now the numbers look like this:
Total rent: $2,250
Mortgage: $1,503
Maintenance reserve: $200
Vacancy reserve: $180
Net cash flow: $367/month or $4,404/year.
Plus principal paydown. Plus appreciation.
You don't need 20% down. You need good math and a plan.
