Can I use a DSCR loan for a duplex, triplex, or fourplex?
The short answer
Yes. DSCR loans work on duplexes, triplexes, and fourplexes, and the ratio uses the total rent from all the units. Expect a down payment of about 25% on most 2 to 4 unit programs. Properties with five or more units usually need a commercial or multifamily loan instead. The Mortgage Advisory finances 2 to 4 unit rentals and can point you in the right direction for larger buildings.
How is the ratio calculated on a multi-unit?
Add up the rent from every unit, then divide by the full monthly payment:
- Unit A: $1,800
- Unit B: $1,750
- Unit C: $1,700
- Total rent: $5,250 ÷ payment $4,700 = DSCR 1.12
Rent comes from the current leases or the appraiser's market rent for each unit.
What if one unit is vacant?
Many programs use the appraiser's market rent for a vacant unit, but some reduce it or want a lease in place. Tell me up front so we pick the right program.
Can I live in one of the units?
Not with a DSCR loan; it's for investment properties only. If you want to live in one unit, look at an FHA, VA, or conventional loan for owner-occupied 2 to 4 unit properties, which can need much less down.
What about 5 or more units?
Five units and up is considered commercial multifamily, which uses different loans and underwriting. Some DSCR lenders do 5 to 8 units under a separate program. I'll tell you which way to go.
Our take
Small multi-units are one of my favorite investor properties: one roof, one insurance policy, several rents. Make sure each unit's rent is realistic and the building's repairs are in your budget, and I'll handle the financing.
