SBA 504 vs 7(a): which one actually buys your building

Most of what is written about SBA 504 versus 7(a) is a feature table. Feature tables are fine until the rules move, and these moved in June 2025 and again in July 2026. A comparison written before either change still reads as authoritative and is still wrong.

Every figure below was re-fetched from the source cited beside it on 17 September 2026, and is what that source said on that date.

The distinction that decides it

Start with what each programme may pay for. That usually settles it before anything about rates does.

SBA’s 504 page lists eligible uses as “the purchase, construction or renovation of existing buildings or land” and “long-term machinery and equipment with a useful remaining life of a minimum of 10 years.” It then lists what 504 proceeds cannot be used for: “working capital or inventory” and “speculation or investment in rental real estate.”

SBA’s 7(a) page lists a longer set: “acquiring, refinancing, or improving real estate and buildings”; “short- and long-term working capital”; “refinancing current business debt”; “purchasing and installation of machinery and equipment, including AI-related expenses”; “purchasing furniture, fixtures, and supplies”; “changes of ownership (complete or partial)”; and “multiple purpose loans, including any of the above.”

So the question is not which programme is better. It is whether the building is the whole transaction.

If you are buying premises your business will operate from and nothing else is happening, that is a fixed-asset project and 504 was built for it. If the purchase is tangled up with buying out a partner, taking on the seller’s operating debt, or funding the first year of working capital, only 7(a) carries all of it in a single facility. A 504 loan cannot be stretched to cover the working capital piece — SBA’s page rules it out in terms.

One more thing before applying: SBA’s 7(a) eligibility list requires that the business “not be able to obtain the desired credit on reasonable terms from non-Federal, non-State, and non-local government sources.” That is the credit-elsewhere test — a real underwriting step, not a formality.

Three parties, and why your equity comes down

The 504 structure is the part most owners have heard of without quite believing.

SBA’s CDC/504 lender page describes three funding sources: “a loan secured from a private sector lender with a senior lien covering up to 50% of the project cost”; “a loan secured from a CDC — backed by a 100% SBA-guaranteed debenture — with a junior lien covering up to 40% of the total cost”; and “a contribution from the borrower of at least 10% equity of the total project cost.”

Fifty, forty, ten. That shape produces a smaller down payment because of lien position, not generosity. The bank in first position lends against half the project cost rather than most of it — a materially safer place to stand. The CDC absorbs the slice in between, on a junior lien, funded by a debenture SBA guarantees in full.

A Certified Development Company is not a bank. SBA’s page describes it as “a nonprofit corporation set up to contribute to the economic development of its community,” and that mandate shows up in the rules. 13 CFR 120.860 requires that “a Project must achieve at least one of the economic development objectives set forth in § 120.861 or § 120.862.” Two routes. The first is jobs. 13 CFR 120.861 provides that “a Project must create or retain one Job Opportunity per an amount of 504 loan funding that will be specified by SBA from time to time in a Federal Register notice” — the regulation sets no dollar figure itself, so the current amount has to be read off the notice in force. 13 CFR 120.802 defines a Job Opportunity as “a full time (or equivalent) permanent job created within two years of receipt of 504 funds, or retained in the community because of a 504 loan.”

The second route is the one owners miss. 13 CFR 120.862 makes a project eligible instead on other economic development objectives — revitalising a business district under a written plan, aiding rural development, expansion of exports, growth of women-owned or veteran-owned small businesses, increasing productivity and competitiveness, reducing energy consumption by at least 10 percent, among others — “if the CDC’s overall portfolio of 504 loans, including the subject loan, meets or exceeds the CDC’s required Job Opportunity average.” Which is why a project creating few jobs is worth taking to a CDC rather than ruling out in advance.

You have to occupy it

This applies to both programmes and is the cleanest bright line in either.

13 CFR 120.131(b) states that where the SBA financing, “whether 7(a) or 504,” is for acquisition, renovation or reconstruction of an existing building, “the Borrower may permanently lease up to 49 percent of the Rentable Property if the Borrower permanently occupies and uses no less than 51 percent of the Rentable Property.”

New construction is stricter. Section 120.131(a) permits permanently leasing “up to 20 percent of the Rentable Property to one or more tenants” only if the borrower “permanently occupies and uses no less than 60 percent of the Rentable Property,” and plans to occupy the remaining unleased space — some within three years, all within ten.

Read those against the 504 exclusion of “speculation or investment in rental real estate” and the design intent is obvious: these are programmes for a business buying its own premises, with a tolerated amount of let space around the edges. A building you will mostly lease out is not an SBA project either way, however good the deal looks.

What you can borrow, and the July 2026 change

SBA’s 7(a) page states: “The maximum loan amount for a 7(a) loan is $5 million.” SBA’s 504 page states: “The maximum loan amount for a 504 loan is $5.5 million.”

That 504 figure needs a footnote most articles omit. 13 CFR 120.931 sets the limit at “an outstanding balance of $5,000,000 for each Borrower and its affiliates” both for projects outside the public policy categories and for those meeting one or more public policy goals. The $5,500,000 figure applies “for each Project” in three named categories only: small manufacturers in NAICS codes 31 to 33 with all US production facilities, projects reducing energy consumption by at least 10 percent, and renewable energy or renewable fuel production projects. An ordinary owner-occupied purchase should plan on five.

Now the change nobody has updated their comparison table for. SBA’s announcement — of a policy that “went into effect on July 4” — states that borrowers may “combine their 7(a) and 504 loans for up to $10 million in SBA-backed financing, an increase from the previous cumulative loan limit of $5 million,” and that “qualified borrowers who secure a 7(a) loan first may access up to $5 million through the 7(a) loan program and up to $5 million through the 504 loan program.”

Note the sequencing: the 7(a) comes first. The announcement does not raise either programme’s individual ceiling — it removes what made the two alternatives rather than a stack.

For an owner buying a building who also needs operating capital, that is a different conversation than the one available a year ago. It makes neither loan easier to get, and “qualified” is doing real work — but the structure exists now, and most of what you will read online still assumes it does not.

Speed, stated honestly

504 has more parties, and its money arrives in stages. CDC Small Business Finance’s own timeline article, published 28 April 2026, says “initial closing generally occurs about 60 days after CDC Small Business Finance receives a complete package ready for underwriting” — and notes that the clock “kicks off when CDC Small Business Finance has the finished package ready to move forward with credit due diligence, not during the earlier back-and-forth while we’re still collecting documents.” The second stage comes later: “for straight purchases, that takeout often occurs roughly 60–90 days after close of escrow; for construction, it occurs after improvements have been completed.”

Between those events the CDC’s portion is not funded, which is why 504 deals carry interim financing: “Interim financing, or bridge financing, serves as a short-term funding option that lasts until the debenture takeout is completed.”

Those figures are one CDC describing its own process, not a programme-wide standard. The structural point travels: a 504 needs a bank and a CDC to both say yes, and a bridge before the debenture funds. A 7(a) is one lender and one closing. If your purchase contract has a hard date and no extension, that difference is not a detail — it is the decision. We have written separately on where 504 fits against the alternatives.

The 2025 rule that invalidates half the advice online

If you are carrying a merchant cash advance, the plan you were sold no longer exists. Under SOP 50 10 8, effective 1 June 2025, merchant cash advances and factoring agreements are not eligible for refinancing with 7(a) loan proceeds. Windsor Advantage’s summary of the SOP states that the prohibition reaches “Standard 7(a) Loans (over $350,000), 7(a) Small Loans ($350,000 or less), SBA Express loans, Export Express loans, and International Trade (IT) loans.” On SBA’s reasoning, the same summary says the structure and high cost “often associated with MCA debt generally does not align with the prudent, long-term financing objectives of the SBA 7(a) loan program.”

Owners in this position often assume the property deal is the vehicle that finally clears the advance off the books. It is not, and structuring the purchase on that assumption wastes months. What the purchase can do is improve the cash flow that made the advance necessary — indirect relief, and anyone advising you should describe it as such.

We set out what changed and what is no longer available separately. A broker still advertising this structure in 2026 is telling you something useful about themselves.

When neither one is the answer

Two cases come up often enough to name. The first is the building you already own and do not occupy enough of. The occupancy percentages above are where a retrofit can fail an SBA test that has nothing to do with the work itself. C-PACE starts from a different place.

The second is geography. USDA Rural Development’s B&I page describes eligible areas as “rural areas not in a city or town with a population of more than 50,000 inhabitants,” adds that “the borrower’s headquarters may be based within a larger city, as long as the project is located in an eligible rural area,” and states that “the loan term will not exceed 40 years.” If your facility qualifies, price USDA B&I alongside both.

Saying so costs a placement now and then. Less than being wrong does.
