House Hacking 101
The single smartest first move in real estate investing: buy a small multi-unit property, live in one unit, and let your tenants cover the mortgage.
The concept in one paragraph
House hacking means buying a property with 2–4 units, living in one, and renting out the rest. The rental income offsets (or entirely covers) your housing payment. Instead of your home being your biggest expense, it becomes your first income-producing asset. When you're ready, you move out, keep it as a full rental, and repeat.
Why the financing is the cheat code
Investment properties normally require 20–25% down. But because you'll live in the property, you can use owner-occupied financing on a 2–4 unit building:
- FHA loan: as little as 3.5% down on 2–4 unit properties. This is the classic house-hack loan.
- VA loan: eligible veterans can do 0% down on multi-unit, same owner-occupancy rule.
- Conventional: low-down-payment options exist (typically 5%+ on duplexes).
The catch, and it's non-negotiable: you must genuinely live in one of the units for at least a year (the owner-occupancy requirement). This isn't a loophole to exploit. It's the deal you make for the low down payment.
The math: an illustrative example
A Nashville duplex, on paper
- Purchase price: $420,000 · Down payment (3.5% FHA): $14,700
- Monthly payment (mortgage + taxes + insurance + FHA mortgage insurance): ~$3,100
- Rent from the other unit: ~$1,700/month
- Your out-of-pocket housing cost: ~$1,400/month, for an entire duplex you own
Compare that to renting a comparable place for $1,700+ while building zero equity. After a year or two, you move out, rent both units (~$3,400 total), and the property starts paying you.
Who house hacking is for
- First-time buyers who want their first purchase to also be an investment.
- Young professionals comfortable living next to tenants.
- Veterans who can pair a VA loan's 0% down with rental income.
- Anyone whose rent keeps rising and wants to flip the script.
The honest risks
- You're the landlord. Late-night maintenance calls, vacancies, tenant screening. It's real work (or a real property-management bill, typically 8–10% of rent).
- Vacancy hurts double. Budget for it: assume each unit sits empty ~5–8% of the year.
- Small multis are competitive. Every investor in Nashville knows this playbook. Good duplexes in rentable areas move fast, so you need financing ready and realistic expectations.
- FHA has property standards. The home must meet FHA appraisal requirements: no major deferred maintenance.
Where to look around Nashville: duplexes and small multis cluster in areas like Madison, Inglewood, North Nashville, and parts of Antioch, but inventory is thin everywhere. See the cash-flow guide → for how to run the numbers before you fall in love.
