For 2–4 unit rental properties, DSCR is calculated using the combined rental income from all units divided by the full PITIA. Each unit's rent contributes to the numerator, but the denominator — the loan payment, taxes, insurance, and HOA — covers the entire property. A triplex with three units renting at $1,200 each generates $3,600 in monthly rent against one PITIA. This can make 2–4 unit DSCR scenarios stronger than single-family because more rent streams support the same payment. However, down payment requirements, program guidelines, and property type restrictions may be different from single-family DSCR.
Higher down payment
2–4 unit DSCR loans often require 25–30% down vs. 20–25% for single-family.
Combined rent calculation
All unit rents are included in DSCR, which can produce stronger ratios than single-family.
Owner-occupied adjustments
If you live in one unit, only tenant-paid rent counts toward DSCR. Owner-occupied units reduce the income calculation.
Appraisal differences
2–4 unit appraisals use the income approach more heavily. Rent schedules must support all units.

More rent streams, better DSCR. The math often looks better on 2–4 unit properties because multiple rent streams support one PITIA. A duplex at $1,500/unit and a single-family at $1,500 rent look very different in DSCR — the duplex has twice the income supporting roughly the same payment.
Vacancy risk is real with fewer tenants. A triplex with one vacancy loses 33% of its rental income. Lenders know this — some may apply a vacancy factor even when all units are currently rented.
Down payment tiers matter. The jump from 20% to 25% or 30% down can be significant on a $500,000 triplex. Budget for higher down payments on 2–4 unit DSCR purchases.
Property taxes and insurance scale up. 2–4 unit properties typically carry higher tax assessments and insurance premiums than single-family homes. The PITIA can be substantially higher even at the same purchase price.

DSCR = Total Monthly Rent (all units combined) ÷ Total Monthly PITIA. All rental income streams are included. For example, a fourplex with units at $1,000, $1,100, $950, and $1,050 = $4,100 total rent divided by the single PITIA covering the whole property.
DSCR programs for 2–4 unit properties typically require 25–30% down. Some programs may go to 25% for duplexes, while fourplexes often require 30%. Requirements vary by lender, credit profile, and property specifics.
DSCR loans are designed for investment/non-owner-occupied properties. If you plan to live in one unit, a conventional owner-occupied loan may be a better fit. DSCR programs typically require the property to be fully tenant-occupied or investment-use.
