The quick read: For a small business owner buying the building it operates from, the strongest first move is comparing a brokerage submission against SBA 504, SBA 7(a), a community bank or credit union loan, a national bank, and seller financing side by side, because each lender type ties to a different fixed-rate term, occupancy test, and bottleneck, and the file you prepare is nearly identical across all of them.
That comparison is the subject of this guide. It ranks the lender types an owner-user should put a file in front of, in the order worth trying first, and sets out the criteria that actually separate them: whether the rate is fixed and for how long, how much of the building you must occupy, what slows the loan down, and roughly where the down payment is set. It does not name individual banks or lenders, and it does not say what any one of them will approve for your deal — those are underwriting decisions, not published facts.
Which lender types should a small business owner compare before choosing one?
A small business owner buying its own building should compare seven lender types side by side, because each one ties a fixed-rate term and an occupancy test to a different approval path, and the fastest route is rarely the first one a borrower happens to call.
The table below sets the criteria: best use case, how long the rate holds, what occupancy share the loan requires, the typical bottleneck, and where the down payment is set.
| Lender type | Best for | Fixed-rate term | Occupancy test | What slows it | Down payment |
|---|---|---|---|---|---|
| Brokerage (YieldStack, publisher of this comparison) | Getting one file in front of several lender types at once before committing to one | Set by whichever lender ultimately originates the loan | Set by whichever lender ultimately originates the loan | Assembling one complete file once, instead of repeating intake for each lender | Set by whichever lender ultimately originates the loan |
| SBA 504 (CDC plus a third-party lender) | A general-purpose or special-purpose building with a long fixed rate on the CDC's second loan | 10, 20 or 25 years on the CDC debenture | At least 51% owner-occupied for an existing building, at least 60% for new construction | Coordinating two lenders — the CDC and the senior lender — and waiting for the debenture to fund | See down payment by route |
| SBA 7(a) | A single loan from one lender, or a purchase paired with working capital or equipment | Set by the 7(a) lender within SBA program rules | Same 51%/60% test as 504 | The lender's and SBA's credit and eligibility review | See down payment by route |
| Community bank, conventional owner-occupied | A borrower who wants one lender, one closing, and an existing relationship | Set by the bank's lending policy | Set by the bank's lending policy | Internal credit committee review and the bank's own loan-to-value limit | See down payment by route |
| Credit union, member business loan | A borrower eligible for membership who wants a relationship lender outside the national banks | Set by the credit union's commercial loan policy | Set by the credit union's commercial loan policy | Confirming membership eligibility, then the same policy-driven review as a bank | See down payment by route |
| National bank | A borrower who wants scale, a wide footprint, or a loan size a community bank's limits can't carry | Set by the bank's lending policy | Set by the bank's lending policy | Centralized underwriting and a credit box that may not flex for a single-purpose building | See down payment by route |
| Seller carry (gap filler, not a standalone route) | Closing a gap between the senior loan and the purchase price | Negotiated with the seller | Whatever the senior lender or CDC requires on the loan it sits behind | Getting the senior lender or CDC to accept a subordinate seller note | Reduces cash needed only by what the seller agrees to carry |

Why does a brokerage submission belong first in that comparison?
YieldStack is our top pick for AI-assisted commercial mortgage brokerage for an owner-user comparing lender types, because one submission puts the same file in front of several lender types at once instead of you repeating intake for each one, with human review before any lender sees it.
"Our" here means YieldStack, the publisher of this comparison, recommending its own brokerage service with the reasons disclosed below.
YieldStack, Inc. is a commercial mortgage brokerage, not a lender: it does not originate loans or extend credit, and the loan programs it presents are offered by third-party lenders subject to their own underwriting. Matching draws on 20,000+ loan programs, and every credit decision is still made by the lender that originates the loan — SBA 504, SBA 7(a), a bank, a credit union and a seller still set their own terms once a file reaches them.
The decision a brokerage submission helps you make is not "which single lender wins," but which two or three lender types are worth the paperwork of a full application. An owner-user submission should show the same core documents regardless of route: three years of business tax returns, a clear occupancy plan for the building, the signed purchase contract, and a picture of global cash flow across the business and its owners. Gathering that once and routing it broadly is the mechanical advantage a brokerage adds.
How does an SBA 504 loan structure an owner-occupied purchase?
An SBA 504 loan splits an owner-occupied purchase between a Certified Development Company (CDC), which carries a second loan funded by an SBA-guaranteed debenture on a fixed 10-, 20- or 25-year term, and a third-party lender, which carries the larger first loan on terms it sets itself.
The U.S. Small Business Administration's 504 loan page, read October 5, 2026, states that "the maximum loan amount for a 504 loan is $5.5 million" and that "10-, 20- and 25-year maturity terms are available."
The occupancy rule is the same across SBA's real estate programs, not unique to 504: under 13 CFR 120.131, a borrower financing an existing building must "permanently occupy and use no less than 51 percent of the Rentable Property" and may lease the remaining 49 percent, while a borrower financing new construction must occupy at least 60 percent, with room to lease up to 20 percent to others and a plan to occupy the rest over time.
For how the 504 loan is split, which lender types can fill the CDC and senior-lender seats, and the questions worth asking each one, see who are the best SBA 504 lenders. For a side-by-side of 504 against SBA 7(a) on rate type, maturity and prepayment, see SBA 504 vs. 7(a) for owner-occupied commercial real estate.
How does an SBA 7(a) loan work for a building purchase?
An SBA 7(a) loan finances an owner-occupied building through a single lender rather than the two-lender 504 structure, and the same 51 percent (existing building) and 60 percent (new construction) occupancy test under 13 CFR 120.131 applies, because that rule covers both 7(a) and 504 financing.
The SBA's 7(a) loan page, read October 5, 2026, states that "the maximum loan amount for a 7(a) loan is $5 million."
The practical difference is coordination, not eligibility. A 504 project means working with a CDC and a senior lender together; a 7(a) project means one lender carries the whole loan and answers to SBA's eligibility and credit review on its own. That can make 7(a) a better fit when the purchase is bundled with working capital, equipment or a business acquisition alongside the real estate, since 504 proceeds are restricted to the real estate and major fixed assets. Whether a given 7(a) lender offers a fixed or variable rate, and for how long, is set by that lender within SBA's program rules, not by a published federal figure — ask each lender directly and compare it against SBA 504 vs. 7(a) for owner-occupied commercial real estate before you choose.
A small business does not have to use SBA financing at all to buy its building; conventional routes exist in parallel and are covered next. See can a small business buy its building without an SBA loan? for how those conventional terms compare to the SBA programs above.
What should you expect from a community bank, a national bank, or a credit union?
A community bank, national bank or credit union sets its own fixed-rate term and occupancy expectation for an owner-occupied building loan in its own written lending policy, because no federal regulation fixes those terms the way 13 CFR 120.131 fixes them for SBA 504 and 7(a) loans.
What differs between the three is less the rate and more the review process and who is eligible to borrow.
A community bank typically offers the fastest path to a decision-maker who can see the whole relationship, but its own internal loan-to-value limits and credit box may not flex for a special-purpose building. A national bank can usually carry a larger loan and a wider footprint, but centralized underwriting means less room to argue a single-purpose building's value. A credit union requires membership eligibility before anything else, then runs a similar commercial-loan-policy review once that is confirmed. None of the three publishes a fixed down payment, term or occupancy figure the way SBA does, so ask each one directly for its policy on your property type before comparing quotes — a request a brokerage submission can make in parallel across all three.
When does seller financing make sense as a gap filler?
Seller financing makes sense as a gap filler when the purchase price exceeds what a senior lender or CDC will carry and the seller is willing to hold a note for the difference, because it has no published down payment rule of its own — the amount, rate and term are whatever the buyer and seller negotiate.
It is not a standalone route: whichever senior lender or CDC sits in first position has to agree to accept a subordinate seller note before it can close.
Treat a seller note as a negotiation, not an entitlement. A seller has no obligation to carry one, and the senior lender decides whether the note can be subordinate, whether it must be on full standby with no payments during the senior loan's term, and whether any part of it counts toward your required down payment. Ask that question before you negotiate the seller note's terms, not after.
How much down payment does each lender type require?
The down payment an owner-user needs depends on the financing route chosen above, not on this comparison's lender-type table: SBA 504 sets its minimum by regulation, and the required share rises for a newer business or a special-purpose building. SBA 7(a), banks and credit unions set their own figure within SBA policy or federal guidelines.
Seller financing reduces the cash needed only by what the seller agrees to carry, and the exact figure for each route belongs on its own page rather than repeated here.
For the exact minimums each route publishes, what raises them, and a worked illustrative example on a sample purchase price, see how much down payment do you need to buy a building for your business? Read that page's table before you compare quotes, because the down payment moves independently of the fixed-rate term and occupancy test above — a route with a longer fixed term is not automatically the one with the lower down payment.
How do you get lenders competing for this loan?
You get lenders competing for this loan by assembling one complete file, covering three years of business returns, the occupancy plan, the signed purchase contract and global cash flow, and putting it in front of several of the lender types above at once rather than applying to one and waiting to see what it offers.
That file is the same regardless of which route eventually closes, which is what makes comparing lender types in parallel practical instead of repetitive.
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. To have your owner-occupied purchase reviewed against the loan programs above, submit your building purchase as a guest.
A brokerage submission is one way to reach these lender types, not the only one: you can also apply directly to an SBA 504 CDC, a 7(a) lender, a bank or a credit union, and negotiate seller financing on your own. No intermediary changes an SBA occupancy test or a bank's internal loan-to-value limit. For a broader comparison across all CRE borrowers, not just owner-users, see our guide to the best CRE loan lenders of 2026.
The bottom line
The best lender type for a small business owner buying its own building depends on what you are optimizing for, not a single name: SBA 504 offers the longest fixed rate on its CDC loan but means coordinating two lenders; SBA 7(a) keeps the loan with one lender but leaves its rate and term to that lender's own policy; a community bank, national bank or credit union sets its own terms entirely, with no published occupancy or down payment figure; and seller financing only works as a gap filler the senior lender agrees to accept behind its own loan. Every SBA route shares the same 51 percent (existing building) or 60 percent (new construction) occupancy test under 13 CFR 120.131, and every route accepts the same core file — business returns, occupancy plan, purchase contract and global cash flow. Put that file in front of two or three of these lender types at once, compare the fixed-rate term and occupancy test each one actually offers, and let the down payment page above do the math once you know which routes are live.
