The quick read: Yes, you can get a commercial real estate loan for a mixed-use building, but the split between apartments and commercial space picks the loan. A building with 5 or more units that is mainly residential fits agency multifamily debt, where Fannie Mae's Multifamily Guide counts commercial rent only from qualifying leases, cuts it 10% and caps it at 20% of effective gross income (EGI). A building that is mostly commercial goes to a bank, CMBS conduit, life company or debt fund that underwrites it as commercial property. If your own business will occupy at least 51% of an existing building, SBA lenders open up. Vacant retail counts for little on any of these until it is leased.
This page answers the eligibility and classification question across lender types. The full owner-user route is in can you use an SBA loan to buy a mixed-use building, and program terms by property type are on the mixed-use loan page.
Can you get a commercial real estate loan for a mixed-use building?
Yes, a mixed-use building qualifies for a commercial real estate loan from banks, agency lenders, CMBS conduits, life companies, debt funds, private lenders and SBA lenders, but each of those lender types reads the same building differently. The share of income from apartments versus storefronts, and who occupies the commercial space, decides which one sizes the loan best.
Mixed-use is not a loan program of its own. It is a property that sits between two underwriting boxes: residential income property and commercial income property. A lender first decides which box the building belongs in, then applies that box's rules to the commercial space. Four facts about your building drive that decision:
- Unit count: agency multifamily debt starts at 5 dwelling units.
- Income split: how much of the rent comes from apartments and how much from retail or office tenants.
- Lease quality: whether the commercial tenants have signed leases, are open and paying, and have time left on the term.
- Occupancy: whether a business you own, or an affiliate, occupies the commercial space.
The reference points below come from the agency guide, the federal SBA rule and the bank call-report instructions, each cited in the sections that follow.
Agency minimum unit count: 5 dwelling units
Agency commercial income haircut: 10% of actual commercial income
Agency commercial income cap: 20% of EGI
SBA owner occupancy, existing building: 51%
SBA owner occupancy, new construction: 60%
How do lenders classify a mixed-use building?
Lenders classify a mixed-use building by asking whether its use is primarily residential or primarily commercial, and the federal bank call-report instructions put that test in writing for apartment buildings with commercial space. Buildings that are not primarily residential fall outside the residential lines and are reported with business properties as nonfarm nonresidential, the commercial bucket.
The FFIEC instructions for Schedule RC-C, which every bank follows when it reports its loans, place apartment buildings "with commercial units combined where use is primarily residential" in the multifamily line. The same instructions put a small residential building with commercial units in the one-to-four family residential line when use is primarily residential, and they put business and industrial properties in the nonfarm nonresidential line. A loan on a nonresidential property counts as owner-occupied when the primary source of repayment is the operating cash flow of the owner or an affiliate, rather than rent from third parties.
The call report does not set a percentage for "primarily." Each bank, CMBS conduit and debt fund writes its own test, usually on share of income, share of floor area, or both, and those thresholds are not published in one place. That is why the same three-story building with two storefronts can be a multifamily loan at one lender and a commercial loan at the next.
The agency guide adds a physical test. Fannie Mae's Multifamily Guide, Section 101, requires an eligible property to contain at least 5 dwelling units, and any commercial space must either be physically part of and connected to the multifamily space, or be a stand-alone building on the same tax parcel. A storefront pad across the parking lot on its own parcel does not ride along.
Which loan fits which kind of mixed-use building?
The loan that fits a mixed-use building follows from its profile: mostly residential buildings of 5 or more units go to agency or bank multifamily debt, small buildings and mostly commercial buildings go to banks and commercial lenders, and owner-occupied buildings open the SBA route. The table maps five common profiles.
| Building profile | Likely loan type | Deciding rule |
|---|---|---|
| Building profile 5+ units, mostly residential | Likely loan type Agency multifamily, bank multifamily | Deciding rule Commercial rent counts only from qualifying leases, cut 10%, capped at 20% of EGI |
| Building profile Under 5 units plus a storefront | Likely loan type Bank, credit union or private lender | Deciding rule Agency multifamily needs 5+ units; call reports class it as one-to-four family residential when primarily residential |
| Building profile 51%+ occupied by your own business | Likely loan type SBA lender, bank owner-occupied loan | Deciding rule Your business occupies at least 51% of an existing building, 60% of new construction |
| Building profile Mostly commercial | Likely loan type Bank, CMBS conduit, life company, debt fund | Deciding rule Underwritten as commercial property under each lender's own classification test |
| Building profile Vacant or unleased retail | Likely loan type Bridge loan from a debt fund or private lender | Deciding rule Agency counts only leased, occupied space; others size the vacancy by lender judgement |
Two cautions on reading the table. First, "mostly" has no single definition outside the agency income cap, so a building near the line should be priced both ways. Second, a building can move rows: signing a third-party lease on a vacant storefront can turn a bridge deal into a permanent multifamily loan, and moving your own business into the ground floor can turn an investor deal into an SBA deal.
How much retail rent counts toward a mixed-use loan?
On agency multifamily debt, retail rent counts only when it comes from an executed lease with an occupying, rent-paying tenant that is not affiliated with the borrower and has at least 12 months left after origination, and the guide then cuts it 10% and caps net commercial income at 20% of EGI.
Those rules sit in two places in Fannie Mae's Multifamily Guide. Section 111, Commercial Leases, limits underwritten income to actual rent from leased and occupied commercial space, requires the remaining lease term to run at least 12 months past the origination date, and excludes tenants affiliated with the sponsor, borrower, key principal or anyone in the ownership structure. It also treats any lease that makes up 5% or more of the property's annual EGI as a Material Commercial Lease with added review and tenant estoppel requirements. Section 203, Income Analysis, deducts 10% of actual commercial income, and its footnote states: "If net commercial income is greater than 20% of EGI, then reduce to 20% of EGI."
Illustrative example (not a real deal). A building's apartments and other income come to $480,000 a year after vacancy, and three signed, occupied retail leases add $150,000.
Retail rent before adjustments: $150,000
After the 10% deduction: $150,000 minus $15,000 = $135,000
EGI with retail counted at the cap: $480,000 + $120,000 = $600,000
Cap at 20% of EGI: 20% x $600,000 = $120,000
Retail rent the lender underwrites: $120,000
Retail rent left out: $30,000 a year
EGI includes the commercial income after the deduction and the cap, so the cap is measured against $600,000, not the $630,000 the building collects.
The $30,000 that falls out of underwriting also falls out of the loan. At an assumed 1.25x minimum debt service coverage ratio, it removes $24,000 a year of debt service the property could otherwise carry ($30,000 divided by 1.25). The fix is rarely to argue with the cap. It is to price the same building with a bank or commercial lender that counts the retail rent in full, then compare the two loans. How the commercial share is measured, and where the agency line sits, is the subject of how much commercial space a mixed-use building can have for a multifamily loan.
Does rent from your own business count, and what about vacant retail?
Rent your own business pays to your building does not count on agency multifamily debt, because the guide excludes commercial tenants affiliated with the sponsor, borrower or key principals, so an owner-user building usually belongs with an SBA lender or a bank owner-occupied loan instead. Vacant retail counts for nothing on agency debt until it is leased.
The SBA route turns the affiliated-tenant problem into the qualifying fact. Under 13 CFR 120.131, a borrower buying, renovating or reconstructing an existing building may permanently lease up to 49% of the rentable property to others if its business permanently occupies and uses no less than 51%. For new construction the business must occupy no less than 60%, and may permanently lease up to 20% to tenants. Apartments upstairs and your shop on the ground floor can qualify when the shop and its related space clear that bar. The details, including which SBA program fits, are in the SBA mixed-use guide.
Vacant storefronts are where lender types split the most. The agency guide underwrites only leased, occupied commercial space, so an empty storefront adds no income to the loan. Banks, debt funds and private lenders make their own call: some give partial credit to a signed lease that has not started, some size only on the residential income, and bridge lenders may lend against a lease-up plan with reserves. Any discount beyond the agency's 10% is lender judgement, so ask each lender how it will treat the space before you sign the purchase contract.
How do you get lenders competing for a mixed-use building loan?
You get lenders competing for a mixed-use loan by sending one complete file, with the rent roll split into residential and commercial units, every commercial lease and trailing operating statements, to several lender types at once, because agency, bank, CMBS and SBA lenders each count the storefront income differently.
There are two ways to run that comparison, and the brokerage route comes first because it does the comparing for you.
- Brokerage route (our recommendation). YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Its software matches the building against 20,000+ loan programs and typically returns 5–8 matches, so the residential and commercial income is tested under agency, bank and commercial rules at once instead of one lender at a time. Its brokers then structure the request, negotiate how the retail leases are counted on your side, and carry the deal toward closing. It is a 5-minute submit, with a median first offer in under an hour, from an institutional 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.
- Direct route. Apply to one bank or lender yourself. You get that lender's classification and that lender's treatment of the storefront income, and you repeat the file for every comparison you want.
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. Older guidance on lender types for this property class is in CRE loans for mixed-use properties.

The bottom line
You can finance a mixed-use building; the question is which lender type reads it best. Mostly residential buildings of 5 or more units fit agency multifamily debt, where commercial rent is cut 10% and capped at 20% of EGI. Mostly commercial buildings go to banks, CMBS conduits, life companies and debt funds, and a business occupying 51% of an existing building opens SBA lending. Lease the storefronts to unaffiliated tenants, split the rent roll, and price the building under more than one set of rules before you commit.
