Looking at 5–10 Units?

This page focuses on 2–4 unit residential rental properties. For 5–10 unit small multifamily scenarios, some DSCR lenders may review 5–8 units and select programs may consider up to 10 units. These scenarios usually require a separate small multifamily review.

Properties with 5 or more units are reviewed through different investor or small multifamily loan paths. Some DSCR lenders may review 5–8 units, and select programs may consider up to 10 units, depending on lender guidelines, rent roll, reserves, property condition, and borrower scenario.

FHA Kiddie Condo / parent co-borrower financing is not intended for 5–10 unit investor properties. For 5–10 unit rental properties, review investor or DSCR financing options.

Scenario: Triplex Purchase With Unit-By-Unit Rent Roll

The Scenario

  • Triplex in Richmond, VA — purchase price $380,000, 25% down ($95,000)
  • Unit 1: $1,350/mo, Unit 2: $1,200/mo, Unit 3: $1,100/mo — total $3,650
  • Loan $285,000, rate 7.125%, P&I ~$1,920/mo, combined DSCR 1.34
  • One unit owner-occupied (house-hack), two tenant-occupied

What Made It Work

  • Strong rent roll — all 3 units leased with documented leases
  • DSCR 1.34 across all units — well above 1.0 minimum for triplex
  • Borrowers 710 credit, combined W-2 income for reserves cushion
  • 7 months reserves = $28,000 documented — met 6-month minimum

2–4 Unit Financing Overview

Financing Duplex, Triplex, and Fourplex Properties

Financing a 2–4 unit investment property is different from financing a single-family rental. Lenders review the property as a small multi-unit asset: total rental income across all units, expense load, occupancy stability, and whether the combined cash flow supports the debt obligation with sufficient cushion.

DSCR loans are frequently used for 2–4 unit properties because the underwriting emphasis is on the property's income-producing potential rather than the borrower's personal income. However, multi-unit properties also introduce additional underwriting variables — vacancy risk, separate metering, higher maintenance costs, and lender-specific expense ratios.

The review process examines each unit's rent, property condition, occupancy status, and whether the combined income supports the loan with a DSCR that meets the lender's minimum.

Property-Specific Review

Duplex, Triplex, and Fourplex Loan Review

2

Duplex Loan Review

Lenders review combined rent from both units, expense allocation, and the resulting DSCR. If one unit is vacant at purchase, lenders may use market rent or apply a vacancy factor. Owner-occupied duplexes may have different loan program options than fully rented investment duplexes.

3

Triplex Loan Review

With three rental income streams, combined rent can produce a stronger DSCR than a single-family rental — but lenders also review the higher expense load and the risk that vacancy in any single unit reduces total qualifying income. Some DSCR lenders apply a higher expense factor to 3–4 unit properties.

4

Fourplex Loan Review

The largest residential property type (1–4 units) eligible for residential DSCR and conventional financing. Properties with 5+ units require commercial financing. Fourplex loans typically require higher reserves, more conservative expense ratios, and stricter property condition review than duplex or triplex loans.

Rental Income & DSCR

Rental Income Across Units and the DSCR Calculation

The DSCR calculation for a 2–4 unit property uses the combined rental income from all units, minus operating expenses, divided by the total debt service. The key difference from single-family underwriting is that expenses are typically calculated as a percentage of the higher multi-unit gross income, and lenders often apply a higher expense factor to account for multi-tenant maintenance, turnover, and management costs.

Lenders will review the rent roll — the documented rent for each unit — along with lease terms, payment history, and whether utilities are separately metered. If utilities are shared, the lender may add a utility expense to the underwriting calculation, which can reduce the DSCR.

For purchases where the property is not fully leased, lenders may use an appraiser's market rent estimate for vacant units but may also apply a vacancy factor that reduces qualifying income. The more units that are vacant at purchase, the more conservative the underwriting tends to be.

DSCR Factors for 2–4 Units

Combined Rent Roll

Sum of documented rent from all units

Expense Ratio

Typically higher for multi-unit (35–45%) than single-family

Vacancy Factor

Lenders may apply 5–10% vacancy regardless of current occupancy

Utility Metering

Separate meters improve NOI; shared utilities add expense

Reserves

Often 6–12 months per unit for multi-unit properties

Condition & Occupancy

Property Condition and Occupancy Review

Property Condition

Multi-unit properties often have more deferred maintenance than single-family rentals. Lenders review the appraisal for condition ratings, required repairs, and any health and safety issues. Properties in below-average condition may have fewer financing options or require repair escrows at closing.

An inspection is separate from the appraisal but can help investors identify condition issues before they become underwriting problems. Significant deferred maintenance — roof, HVAC, electrical, plumbing — should be discussed during the scenario review.

Occupancy and Lease Review

Lenders review the current occupancy status of each unit. Fully occupied properties with documented leases and payment history present the strongest case. Properties with vacant units, month-to-month tenants, or units rented below market may face more conservative underwriting.

If the property is partially owner-occupied, lenders may treat the owner's unit differently in the DSCR calculation — some programs exclude owner-occupied units from qualifying income entirely, which can significantly change the DSCR result.
