The quick read: Yes, you can get a DSCR loan on a small mixed-use building, such as a storefront with a few apartments above it, from investor DSCR lenders and small-balance commercial lenders. The loan qualifies on the building's rent rather than your personal income. The deciding variables are lender-specific: how much commercial space the program accepts, and whether the storefront's rent is counted in full, discounted or excluded from the coverage ratio.
Loan type: investor DSCR or small-balance commercial loan, business purpose
Qualifies on: the property's rent against its debt payment, not the borrower's personal income
Consumer-mortgage rules: non-owner-occupied rental property is deemed business purpose regardless of the number of housing units (CFPB official interpretation of 12 CFR 1026.3(a))
Agency alternative: a Fannie Mae mixed-use loan requires a one-unit dwelling the borrower occupies as a principal residence (Selling Guide B2-3-04, October 8, 2025)
Bank supervisory limit: 85% loan-to-value for improved property, which a bank may exceed for a limited share of its loans (12 CFR Part 34, Subpart D, Appendix A, 2025 edition)
Variables set by each lender: commercial-share limit, unit cap, commercial-rent treatment, minimum DSCR, leverage, prepayment

Can a DSCR lender finance a building with a storefront and apartments?
Yes, a DSCR lender can finance a building with a storefront and apartments, provided the program accepts mixed-use collateral and the building's rent covers the proposed payment by the lender's required ratio. Many residential-style DSCR programs are written for one-to-four-unit rentals, so mixed-use is often an exception or a separate product.
A DSCR loan is sized on the debt service coverage ratio: the property's income divided by its debt payment. The borrower's tax returns and pay stubs matter less, because the building is expected to carry its own loan. That makes the product a natural fit for an investor who owns several rentals and whose personal income is hard to document.
The complication with mixed-use is that two kinds of lender approach the same building from opposite directions. A residential-style DSCR lender sees a small rental with a shop attached and asks whether the shop is small enough to ignore. A small-balance commercial lender sees a small commercial property with apartments attached and underwrites the leases, the tenant and the location more like a retail deal. The same building can get very different answers from each, which is why the property description you submit matters as much as the numbers.
Three questions sort the building before you ask for terms. How much of the gross building area, and how much of the rent, is commercial? How many residential units are there, and how many commercial units? Is the storefront leased, owner-used or vacant? Lenders publish their answers to those questions in program guidelines, and the cutoffs differ from lender to lender.
Why is a small mixed-use DSCR loan a business-purpose loan?
A small mixed-use DSCR loan is a business-purpose loan because federal Truth in Lending rules exempt credit extended primarily for a business or commercial purpose, and the CFPB's official interpretation deems credit on non-owner-occupied rental property a business purpose regardless of the number of housing units.
Regulation Z, at 12 CFR 1026.3(a), exempts "an extension of credit primarily for a business, commercial or agricultural purpose." The CFPB's official interpretation of that section then says: "Credit extended to acquire, improve, or maintain rental property (regardless of the number of housing units) that is not owner-occupied is deemed to be for business purposes." A storefront-and-apartments building you buy to rent out fits that description.
The same interpretation treats owner-occupied buildings differently. Credit to acquire an owner-occupied rental property is deemed business purpose "if it contains more than 2 housing units," and credit to improve or maintain one is deemed business purpose if it contains more than 4. If you plan to live in one of the apartments, the analysis changes, and the lender will ask about occupancy before it decides which product applies.
Why this matters to the borrower: business-purpose status is what lets a lender underwrite on rent instead of personal income. It also means the consumer-mortgage disclosures and protections you may know from a home purchase may not apply, so read the note, the guaranty and the prepayment terms yourself, with your own attorney if needed.
How do DSCR lenders count the commercial rent in a mixed-use building?
DSCR lenders count commercial rent in a mixed-use building in one of three ways, set by each lender's program: counted in full, counted after a discount for vacancy and re-leasing risk, or excluded so the apartments alone must cover the payment. Which treatment applies can move the coverage ratio more than the interest rate does.
No allowlisted public source we found publishes the cutoffs or the discount, so this page states the mechanism without figures. The logic is consistent, though. Apartment rent is usually treated as the more predictable income: many units, short leases and a deep tenant pool. A single storefront is concentrated risk: one tenant, a longer re-leasing period if it leaves, and possibly tenant-improvement and leasing costs to fill it. A lender that does not want that risk either haircuts the storefront income or leaves it out entirely.
The illustrative math below is hypothetical, built only to show how the treatment changes the ratio. It is not a quote, a rate or a lender requirement.
Table: Hypothetical coverage on one building under three rent treatments
| Treatment (hypothetical) | Apartment rent counted (3 units) | Storefront rent counted | Total counted rent per month | Hypothetical monthly debt payment | Resulting coverage |
|---|---|---|---|---|---|
| Counted in full | $4,500 | $2,500 | $7,000 | $5,000 | 1.40x |
| Discounted by a hypothetical 25% | $4,500 | $1,875 | $6,375 | $5,000 | 1.28x |
| Excluded | $4,500 | none | $4,500 | $5,000 | 0.90x |
The same building swings from comfortable coverage to failing coverage on the commercial-rent decision alone. A related point: a residential-style DSCR test often divides gross rent by the full housing payment, while a commercial test divides net operating income by debt service. Ask each lender which formula it uses, because a ratio quoted on one basis is not comparable to a ratio on the other. Many programs also calculate DSCR on market rent from the appraisal rather than on in-place leases, which is a pro-forma figure and works in one direction: it can qualify a building whose current leases would not.
Which lender types finance small mixed-use rentals, and how do they compare?
Four lender types finance small mixed-use rentals, namely investor DSCR lenders, small-balance commercial lenders, banks and credit unions, and only banks have a published, dated supervisory loan-to-value limit. Every other term in the table is set program by program, so use it to sort your questions, not to predict a quote.
Table: Small mixed-use lender types (framework as of October 2026, not a ranking)
| Lender type | Commercial-share limit | How commercial rent is counted | Leverage | Prepayment |
|---|---|---|---|---|
| Investor DSCR (non-QM, business purpose) | Set per program; no dated public benchmark found | Full, discounted or excluded, per program | Set per program; no dated public benchmark found | Ask for the full schedule in writing |
| Small-balance commercial | Often underwritten as commercial outright; confirm | Usually counted, underwritten against the lease and tenant | Set per lender; no dated public benchmark found | Ask for the full schedule in writing |
| Bank | Set by the bank's own credit policy | Underwritten case by case | 85% supervisory LTV for improved property, which banks may exceed for a limited share of loans (12 CFR Part 34, Subpart D, App. A, 2025 edition) | Negotiated per relationship |
| Credit union | Set by the credit union's own commercial lending policy | Underwritten case by case | No dated public benchmark found | Negotiated per relationship |
The bank row has a public anchor because federal guidelines tell banks: "Institutions should establish their own internal loan-to-value limits for real estate loans. These internal limits should not exceed the following supervisory limits." The same appendix defines an improved property loan to include "1- to 4-family residential property that is not owner-occupied," "residential property containing five or more individual dwelling units" and "completed commercial property," and sets the limit at 85%. The appendix says it may be appropriate in individual cases to make loans above the supervisory limits, but the aggregate of all such loans "should not exceed 100 percent of total capital," with commercial, multifamily and other non-1-to-4 family loans held within 30 percent of total capital. The 85% figure is a supervisory guideline, not a typical offer and not a hard cap on any single loan.
A bank or credit union is often the better home for a small mixed-use building when the storefront tenant is local, the borrower has a deposit relationship, or the building needs a lender that will look at the whole picture rather than a fixed program grid. A DSCR lender is often the better home when you hold the property in an LLC, own several rentals, and want qualification on the building's income alone. Rates follow the same split; for how DSCR pricing is built, see DSCR loan rates.
Why doesn't a Fannie Mae mortgage work for an investor-owned mixed-use building?
A Fannie Mae mortgage generally does not work for an investor-owned mixed-use building because the Selling Guide's mixed-use rule requires a one-unit dwelling that the borrower occupies as a principal residence, with the borrower owning and operating the business, and the property must be primarily residential in nature.
Fannie Mae's Selling Guide, section B2-3-04 (published October 8, 2025), lists those conditions directly: "The property must be a one-unit dwelling that the borrower occupies as a principal residence," "The borrower must be both the owner and the operator of the business," and "The property must be primarily residential in nature." It adds that the dwelling may not be modified in a way that hurts its marketability as a residential property.
That describes a shopkeeper who lives above the shop, not an investor who leases the storefront to a tenant and rents out the apartments. If you are the investor, the agency single-family path is closed by its own terms, and the realistic choices are the four lender types in the table above. Larger mixed-use buildings can fit agency multifamily programs, which have their own commercial-space limits and unit minimums; this page does not cover them.
What happens if the storefront is vacant when you apply?
A vacant storefront usually means the lender sizes the loan on the apartments alone, asks for a lease-up plan, or declines the program and points you to a bridge or bank loan, because there is no in-place commercial income to count and a vacant retail space carries real re-leasing time and cost.
In the hypothetical table above, a vacant storefront looks like the "Excluded" row: the apartments must cover the whole payment. If they cannot, three moves are common. Bring more equity so the smaller loan covers on residential rent alone. Sign the commercial lease before closing, with the tenant in place and paying, and give the lender a copy of the lease and evidence of payment. Or finance the acquisition with a short-term loan, lease the space, and refinance into a DSCR loan once the storefront has a rent history.
If the market-rent figure in the appraisal is what qualifies the deal, check that the appraiser's commercial rent comparables are real storefronts in the same corridor. Pro-forma rent that the market does not support will be the first thing a careful lender cuts.
Buying a storefront-and-apartments building to rent out? What will a DSCR lender count?
If you are buying a storefront-and-apartments building to rent out, a DSCR lender will count the apartment rent and, depending on its program, all, part or none of the storefront rent, so the fastest route is to show several lenders the rent roll, the commercial lease and the floor-area split at once.
YieldStack is a commercial mortgage brokerage, not a lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Prepare four items before you ask: the rent roll for every unit, the storefront lease with its expiration date and any options, the square footage split between residential and commercial space, and the trailing operating statement or, for a purchase, the seller's income and expense figures. Then submit the building for lender matches. For mixed-use loan structures beyond DSCR, see mixed-use loans.
The bottom line
A small mixed-use building can be financed with a DSCR loan, and as a non-owner-occupied rental it is business-purpose credit under the CFPB's interpretation of Regulation Z. The terms turn on choices each lender makes: how much commercial space it accepts and how it counts the storefront's rent. Price the deal with all three rent treatments, compare DSCR, small-balance, bank and credit union answers side by side, and get the prepayment schedule in writing before you sign.
