Triple-Decker and 2-4 Unit DSCR Loans

TL;DR

The triple-decker is Massachusetts’s native asset class. DSCR loans treat your two-, three- or four-unit building as one loan qualified on the combined rent of all its units. These are business-purpose loans for non-owner-occupied Massachusetts investment property, arranged by a broker that shops wholesale lenders, not made by us.

Who this fits

Buyers targeting classic triple-deckers in Worcester, Boston’s outer neighborhoods or the Merrimack Valley mill cities
Owners of doubles and fourplexes who want one loan sized on combined rents rather than personal income
House-hackers moving out and converting to full investment use, once the property is non-owner-occupied
Investors refinancing small multis out of short-term renovation debt

The numbers that decide the deal

The rent figure. All units combined. Leases where they exist, plus the appraiser’s market-rent schedule for vacant units, on the small-residential income form.

One payment. A single PITIA: principal, interest, the full tax bill, the landlord policy and any shared costs the lender includes. The combined rents are divided by that one payment.

Condition matters. Older multis get real scrutiny on roofs, porches, wiring and heating. Budget for the inspection findings; they affect both insurance and value.

Why triple-deckers fit DSCR so well

Massachusetts built its rental stock vertically. From Dorchester to New Bedford, three-story wood-frame buildings with one apartment per floor house a huge share of the state’s renters, and they trade constantly among investors. They are also a natural fit for DSCR underwriting: multiple income streams under one roof means one vacancy rarely breaks the ratio.

Lenders like the redundancy too. A single-family rental that loses its tenant goes to zero rent; a triple-decker that loses one tenant keeps two-thirds of its income. Some lenders reflect that in more flexible treatment of 2-4 unit properties, particularly when the units are separately metered and self-contained.

Underwriting a Massachusetts multi, unit by unit

The rent schedule is where deals are won or lost. On a 2-4 unit property the appraiser completes a small-residential income approach, comparing each unit to similar rentals nearby. Bring current leases, a rent ledger and your own rent research. If a long-term tenant pays below market, some lenders will use the lease while others use market rent, and that difference can decide which lender we place you with.

Older multis carry building-system questions that single-family homes dodge. Porches on a triple-decker are structural and insurers ask about them. Separate utilities keep accounting clean and are preferred by many lenders. Oil heat, older electrical panels and any remaining fuse boxes can push insurance quotes up and should be priced into your ratio before you fall in love with a deal.

Lead paint is a Massachusetts reality in pre-1978 stock. It rarely blocks financing, but compliance history, deleading documentation and any letters of compliance are worth gathering early, both for the file and for your own protection as a landlord.

Common questions

Do all units need to be rented for the loan to work?

No. Lenders typically combine actual leases for occupied units with the appraiser’s market rent for vacant ones. A fully vacant building can still qualify on market rents with some lenders.

Can I live in one unit and still get a DSCR loan?

No. If you or a family member will occupy any unit, the property is owner-occupied and outside the business-purpose scope of these loans.

Is a triple-decker treated as residential or commercial?

One-to-four unit properties are residential for DSCR purposes, which keeps pricing and documentation simpler than five-plus-unit commercial financing.
