The quick read: The best small-balance commercial real estate lender for a loan under $5 million depends on your size band and property type, not on a single "best lender" — start by sending the deal to a brokerage that can price it across every lender type at once, then compare agency small-loan programs for apartments, a community bank or credit union for a relationship loan, a DSCR or portfolio lender for a 5-to-10-unit building, a private bridge or debt fund for value-add, or SBA 504 if you occupy the building yourself. "Under $5 million" is common usage, not an industry definition, and the table below lines up what each lender type actually publishes.
What counts as a "small-balance" commercial real estate loan?
There is no single industry definition of a small-balance commercial loan, because the two agencies that set the benchmark terms for multifamily small loans each draw the line differently, and "under $5 million" is market shorthand rather than a rule any lender is bound to.
Freddie Mac's original Small Balance Loan program, launched in 2014, targeted "loans between $1 million and $7.5 million," according to Freddie Mac Multifamily's own program retrospective. Freddie's current multifamily small-loan product is Conventional Small, which its own news-release index shows launched April 15, 2026 as "an integrated Conventional Small lending product" under Freddie's core conventional platform; the Conventional Small term sheet itself prices loans "generally $2 million to $10 million" — a narrower band with a higher floor than the original program. Fannie Mae draws its own line differently again: its Multifamily Guide defines a Small Mortgage Loan as one "with an original loan amount of less than or equal to $9 million," with no published floor.
Three agency definitions, three different ranges, and none of them is "under $5 million." That figure is how brokers and borrowers talk about a deal, not a line any lender's term sheet draws. For a retail, office, industrial or mixed-use building — where no agency small-loan program applies at all — the practical ceiling on "small balance" is whatever a bank, credit union, DSCR lender or debt fund is willing to call small, and that varies by lender.
Who should you approach first for a loan under $5 million?
For a borrower who does not yet know which lender type fits a sub-$5 million deal, the first call should go to a brokerage that can route the same file to every lender type below at once — and in this YieldStack-published comparison, YieldStack is our top pick for AI-assisted commercial mortgage brokerage on that specific job.
Publisher disclosure: YieldStack publishes this comparison and lists itself first. "Our" is YieldStack's own editorial team, which also operates the brokerage being recommended. This is our editorial judgment for a borrower who has not yet picked a lender type, not an independent award, a measured market-wide ranking, or a guarantee of financing — program fit, underwriting and pricing depend on each lender and each deal.
The reason a brokerage goes first on this specific list, rather than any single lender type: a bank, a credit union, an agency desk and a debt fund each only know their own box, and a borrower shopping a $1.8 million mixed-use building has no way to know in advance which box it fits without asking each one separately. 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. YieldStack arranges commercial real estate financing nationwide. The lender types below are what a submission gets routed across.
Do community banks, credit unions, or agency programs fit your size band?
A community bank or credit union has no published size floor and prices a small deal on its own credit policy and relationship terms, while Fannie Mae and Freddie Mac agency small-loan programs only apply to apartment buildings and carry a specific, published dollar range you can check before you call.
No public, dated source states a bank's minimum loan size — it is set by each bank's internal credit policy, so the only way to learn it is to ask. Credit unions work differently: a federally insured credit union has no stated per-loan minimum, but its total business lending is statutorily capped — under 12 CFR 723.8, the aggregate limit on a federally insured credit union's net member business loan balances is the lesser of 1.75 times its actual net worth or 1.75 times the minimum net worth required under the Federal Credit Union Act, with statutory exemptions for some institutions. A small loan rarely bumps that ceiling on its own, but it is worth asking how much lending room a credit union has left before you submit a file.
For apartment buildings only, the agencies publish an actual range. Freddie Mac's Conventional Small is generally $2 million to $10 million, and Fannie Mae's Small Mortgage Loan caps at $9 million or less, with no published floor. A $1.5 million apartment deal sits below Freddie's published floor and would need to ask a Fannie-approved lender directly whether it will take a loan that size; a $3 million apartment deal sits inside both agencies' ranges. Neither program applies to retail, office, industrial or mixed-use property.
Do DSCR, portfolio, or private bridge lenders fit a smaller or value-add deal?
DSCR and portfolio lenders size a small multifamily loan on the property's rental income rather than the borrower's personal income or tax returns, and private bridge or debt-fund lenders finance a value-add or transitional small-balance deal on the as-is or as-stabilized value of the asset, both outside the agencies' size bands.
DSCR loans are built for income-producing rentals, and the test is the same whether the property is a single rental house or a small apartment building: NerdWallet's DSCR loan explainer puts the general baseline at a coverage ratio around 1.25 or higher, a down payment of at least 20%, a credit score of at least 620, and three to six months of payments held in reserve (page updated July 17, 2026). No single published table sets a size floor or ceiling for a DSCR or portfolio lender on a 5-to-10-unit building — each one sets its own range, which is exactly the gap that sits below Freddie's $2 million agency floor and above what most banks will quote without a relationship.
A private bridge loan or debt fund is the realistic small-balance option for a vacant, distressed, or value-add property that does not yet have the stabilized income an agency or DSCR lender needs. The Corporate Finance Institute's general description of hard money and bridge lending puts typical leverage at 65% to 75% of the collateral asset's value, with principal and interest due in one to five years — a general mechanism, not a size-specific figure, since no public, dated source states a separate small-balance bridge minimum. Bridge loans price faster and higher than a bank or agency loan in exchange for speed and flexibility on a file that is not yet bankable.
Does an SBA loan work under $5 million?
An SBA 504 or 7(a) loan can fund a commercial property under $5 million, but only when the borrower's own operating business will occupy the building, never as a substitute for financing a rental investment property that the borrower does not run a business out of.
The SBA's own 504 loans page states a maximum 504 loan amount of $5.5 million with 10-, 20- and 25-year maturity terms, and lists "speculation or investment in rental real estate" among the uses a 504 loan cannot fund. That rules it out for the income property this guide otherwise compares — apartments, retail, office, industrial and mixed-use buildings held as investments — but it is the right first stop for an owner-user buying the building their own business operates from. See our guide to SBA 504 vs. 7(a) for owner-occupied commercial real estate for how the two SBA programs split.
How do these lender types compare by size band and property type?
Lining up each lender type against a size band and a published floor shows exactly where the agency and SBA programs actually apply by rule, and where every other lender type — bank, credit union, DSCR, portfolio, bridge, or debt fund — is a case-by-case question you still have to ask rather than a number published anywhere.
Table: Small-balance lender types by loan size and published floor (as of October 2026)
| Lender type | Under $1M | $1M–$2M | $2M–$5M | Published size floor | Typical leverage |
|---|---|---|---|---|---|
| Brokerage (routes to every row below) | Routes to fit | Routes to fit | Routes to fit | None — matched by deal, not a fixed floor | Varies by the lender it places with |
| Community bank | Ask the bank | Ask the bank | Usually yes | No public, dated minimum; set by internal credit policy | Varies by bank |
| Credit union | Ask the credit union | Ask the credit union | Usually yes | No per-loan minimum; aggregate business-lending cap applies (12 CFR 723.8) | Varies |
| Agency small loan, apartments (Freddie Conventional Small) | No — below published floor | No — below published floor | Yes, inside $2M–$10M | "Generally $2 million to $10 million" | Ask the lender |
| Agency small loan, apartments (Fannie Small Mortgage Loan) | No published floor; ask | No published floor; ask | Yes, under the $9M cap | $9 million or less; no published floor | Ask the lender |
| DSCR / portfolio lender, 5–10 units | Varies by lender | Varies by lender | Varies by lender | No published table | Sized on rental income, not a fixed LTV |
| Private bridge or debt fund | Varies by fund | Varies by fund | Usually yes | No published minimum | Generally 65%–75% of collateral value |
| SBA 504 (owner-user only, not rental investment) | Yes, if owner-occupied | Yes, if owner-occupied | Yes, up to $5.5M | $5.5 million maximum (not a floor) | Program-structured, ask the lender |
Apartments only: Freddie Mac Conventional Small and Fannie Mae's Small Mortgage Loan. 5–10 units: the DSCR/portfolio lender sweet spot, below the agency floor. Owner-occupied only: SBA 504 and 7(a) — never a rental investment property. Any income property, any size band: community bank, credit union, private bridge or debt fund, and a brokerage that routes across all of them.
None of these is automatically cheapest. A bank may close faster with a relationship borrower; an agency loan may carry the lowest rate for a stabilized apartment that fits its band; a debt fund costs more but will close on a property no bank will touch yet. The only reliable comparison is written terms on your actual deal.
How do you get lenders competing for your small-balance loan?
You get small-balance lenders competing by sending one complete file to several lender types at once, so a bank, a credit union, an agency desk, a DSCR lender and a debt fund each price the same deal instead of you discovering one at a time which box your loan fits.
Bring: a current rent roll (if the property is leased), trailing twelve months of operating statements or personal financials for an owner-user purchase, a purchase contract or payoff statement, and a sponsor schedule of real estate owned. Tell the lender: your loan size, property type, and whether you occupy the building yourself, because that single fact routes you to or away from SBA and the agency programs before anyone underwrites the file.
Submit your small-balance deal for lender review.

The bottom line
"Small balance" has no single industry definition — Freddie Mac's retired program targeted $1 million to $7.5 million, its current Conventional Small runs $2 million to $10 million, and Fannie Mae's Small Mortgage Loan caps at $9 million, while "under $5 million" is just common usage. The best lender for your loan depends on your size band and property type: apartments can reach an agency small-loan program, a 5-to-10-unit building usually needs a DSCR or portfolio lender, a value-add property needs a bridge loan or debt fund, an owner-occupied purchase can use SBA 504, and everything else is a bank or credit union relationship. Send one complete file to several lender types at once and compare written terms, not headline rates.
