What Is Triplex?
A triplex is a 3-unit residential building. Each unit has its own entrance, kitchen, and bathroom. Triplexes qualify for residential financing (FHA, conventional) when you house-hack—live in one unit, rent the other two. That can mean 3.5% down with FHA or 5% with conventional. Three units spread vacancy-risk better than a duplex and often yield higher gross-rental-income per dollar invested than a single-family.
A triplex is a residential building containing three separate dwelling units—each with its own entrance, kitchen, and bathroom—typically under one roof.
At a Glance
- What it is: Building with three separate residential units
- Why it matters: Qualifies for owner-occupied financing; 3-unit income diversification
- Financing: FHA/conventional if owner-occupied; otherwise commercial or portfolio
- Typical layout: Side-by-side or stacked units
- Best for: House hackers wanting more units than a duplex
How It Works
Financing advantage. With FHA, you can buy a triplex with 3.5% down and live in one unit. The other two units' rent counts toward your income for qualification. On a $380,000 triplex in Memphis, that's $13,300 down instead of 15–25% for a non-owner-occupied investment property.
Income structure. Each unit rents independently. A triplex in Indianapolis might rent for $1,100, $1,150, and $1,200 per unit—$3,450 total. Operating-expenses (taxes, insurance, maintenance, vacancy-rate reserve) might run 40–50% of gross. Your mortgage-offset from the two rented units could cover most or all of piti.
Management. Three units mean three leases, three tenants, and more turnover than a duplex. But one vacancy leaves you with two-thirds of income—better than a duplex where one vacancy halves your rent.
Scarcity. Triplexes are less common than duplexes or fourplexes. Inventory can be limited in some markets.
Real-World Example
Chris in Birmingham. Chris bought a triplex for $265,000 with 5% down ($13,250). He lived in the largest unit (1,100 sq ft) and rented the other two for $950 and $1,000. His piti was $1,720. The two rented units brought in $1,950. After vacancy-rate reserve (8%) and maintenance, his effective-rent covered the mortgage with about $180 left over. He was effectively living for free while building equity.
Pros & Cons
- Qualifies for low down-payment owner-occupied financing
- Three units diversify vacancy risk
- Often better rent-per-dollar than single-family
- Scalable—learn property management on a smaller asset
- Fewer triplexes on market than duplexes
- Three tenants to manage
- Some lenders treat 3–4 units as commercial (stricter terms)
Watch Out
- Financing gap: Not all lenders do triplexes; shop for FHA/conventional
- Deferred maintenance: Older triplexes may need capex; factor into deal-analysis

The Takeaway
A triplex is a strong house-hacking vehicle: low down payment, three income streams, and better vacancy cushion than a duplex. Find one that pencils and where you're willing to live.
