A duplex, triplex, or fourplex gives you the best of both worlds as a California investor: rental income from multiple units, residential-style financing, and the DSCR loan’s no-income-verification advantage. Combined rents often push DSCR ratios well above 1.0 — making multifamily 2–4 units one of the easiest DSCR loan scenarios to qualify.
How DSCR Works on 2–4 Unit Properties
The appraiser provides market rent for each unit. All unit rents are added together as gross monthly income. That combined income is divided by total PITIA to get DSCR.
Example — Triplex in Riverside: Three units at $1,600, $1,650, $1,700/mo = $4,950 combined. PITIA on a $650K purchase (25% down, 7.5%): $4,070/mo. DSCR = 4,950 ÷ 4,070 = 1.22 ✅
DSCR by Unit Count — California Examples
| Property | Market | Combined Rents | Est. PITIA | DSCR |
|---|---|---|---|---|
| Duplex (2 units) | Sacramento | $3,800/mo | $3,200/mo | 1.19 ✅ |
| Triplex (3 units) | Riverside | $4,950/mo | $4,070/mo | 1.22 ✅ |
| Fourplex (4 units) | Fresno | $5,600/mo | $4,100/mo | 1.37 ✅ |
| Duplex | East Bay | $5,400/mo | $6,200/mo | 0.87 ⚠️ sub-1.0 |
Duplex vs. Triplex vs. Fourplex — What to Know
| Property Type | Financing Type | Min Down (DSCR) | DSCR Calculation |
|---|---|---|---|
| Duplex (2 units) | Residential DSCR | 20–25% | Both units combined |
| Triplex (3 units) | Residential DSCR | 20–25% | All 3 units combined |
| Fourplex (4 units) | Residential DSCR | 20–25% | All 4 units combined |
| 5+ units | Commercial DSCR | 25–30% | NOI-based calculation |
Important: 2–4 units are classified as residential for DSCR loan purposes. This means easier qualification, lower down payment requirements, and more lenders available vs. commercial 5+ unit programs. The fourplex is the maximum unit count for residential DSCR treatment — a 5-unit and above is treated differently.
Owner-Occupied vs. Non-Owner Occupied
DSCR loans are investment property only — you cannot live in one of the units on a DSCR loan. If you want to house-hack (live in one unit, rent others), you’d need a conventional or FHA loan. But if you’re buying purely as an investor, DSCR is the cleanest path: no income verification, no employment check, and you can vest in an LLC.
