Financing a triplex or fourplex
Can I finance a 3- or 4-unit rental property with a DSCR loan?
A fourplex is the largest property this directory’s residential rental programs will touch — one more unit and the deal moves to an entirely different appraisal method, loan product, and lender roster on this site.
- DSCR rental loan Three and four units are still classified as residential 1-4 unit property, which is the ceiling most DSCR programs are built to underwrite before a deal crosses into multi-family.
- Multi-family / apartment financing A fourplex is one unit short of the five-unit line where a property becomes commercial multi-family for appraisal and underwriting purposes — bringing it to a multi-family desk one unit too early just adds a more complex process for no reason.
Lenders in the directory
No lender here publishes a rule for this
This is an underwriting judgment, not a published threshold. None of the 37 lenders in the directory states a policy on it, so there is no honest way to build a shortlist — and a list computed only from which products a lender writes would tell you nothing you could act on.
What matters here is how the file is presented rather than which lender receives it. The sections below cover that. When you are ready to approach lenders, the directory shows what each one does publish, with the date it was verified.
The five-unit line, and why it exists
Residential mortgage underwriting — agency and non-QM alike — draws its line at four units. A property with five or more units is appraised on an income-capitalization basis as commercial real estate; a 1-4 unit property is appraised primarily on comparable sales, with income treated as a qualifying input rather than the basis of value. A triplex or fourplex sits at the very top of the comparable-sales side of that line, which is why it is grouped with single-family and duplex financing in this directory rather than with the multi-family page.
Aggregating three or four rent lines
DSCR on a triplex or fourplex sums every unit’s rent — actual lease amounts where tenants are in place, the appraiser’s market-rent estimate on Form 1025 for any vacant unit — against the single blended mortgage payment on the property. One underperforming unit in a fourplex has less effect on the total ratio than the same shortfall would on a duplex, simply because it is diluted across more units.
Comparable-sale scarcity is the real friction point
Three- and four-unit buildings trade less frequently than single-family homes or duplexes in most markets, so the appraiser’s comparable pool is thinner and pulled from a wider radius or a longer time window. That is the most common source of a low appraisal on this property type, not anything about the borrower or the lease.
What to have ready
- Rent roll for all units, with lease start dates
- Unit mix and square footage breakdown
- Recent comparable 3-4 unit sales if you have them, to compare against the appraisal

Terms used on this page
- Form 1025 (Small Residential Income Property Appraisal Report) — Form 1025 is the standard appraisal report used for two-to-four unit residential properties. Unlike the one-unit report, it includes an income approach and a unit-by-unit rent analysis, since these properties are typically rented.
- Debt Service Coverage Ratio (DSCR) — DSCR is a property’s gross monthly rent divided by its total monthly mortgage payment. A DSCR of 1.00 means the rent exactly covers the payment; 1.25 means rent exceeds the payment by 25%.
- Comparable Rent Schedule — A comparable rent schedule is the appraisal method of estimating a property’s market rent by identifying similar rented properties nearby, adjusting their rents for differences, and reconciling them into a single opinion. On one-unit properties this method is formalized as Form 1007; on two-to-four unit properties it is built into Form 1025.
