Most owners approach SBA lending the way they’d approach buying anything else. Line the three programs up, compare the rates and the limits, pick the best one. It’s a sensible instinct, and it leads people astray more often than you’d expect.
The three programs aren’t really in competition. Each was built for a different kind of spending, and in practice the thing you’re buying usually decides which one applies before rates enter the conversation at all. Match them correctly and you’ll close faster on better terms. Match them badly and you’ll either overpay or spend three months in underwriting for a loan that was never the right shape to begin with.
So here’s how each one actually works, and what belongs inside it.
Start with what you’re buying
One question does most of the sorting: what are you purchasing, and how long will it be around?
If it’s something that’ll still be standing in twenty years, like a building or a production line, you want long, fixed-rate money that matches the life of the asset. If it’s something that turns over inside a year, like inventory or payroll through a slow season, you want flexibility and speed, and the rate matters less than you think. If you’re somewhere in the middle, buying a competitor for instance, you want the generalist.
Those three shapes line up almost exactly with the three programs. It’s also why banks that do a steady volume of loans for small business will nearly always ask about use of funds before anything else. They already know where the answer is heading.
The 504
The 504 does one thing. It finances owner-occupied real estate and long-life equipment, and within that lane it’s the most capital-efficient option on the table.
The structure is the whole point. A bank takes roughly half the project in first position, a Certified Development Company funds up to 40% through an SBA-guaranteed debenture sitting behind it, and you put in about 10%. Compare that to a conventional commercial mortgage, where 20% to 30% down is normal, and the cash you keep in the business is considerable. The CDC portion caps at $5 million, or $5.5 million for small manufacturers and qualifying energy projects, with terms of 10, 20 or 25 years at a rate that’s fixed the day the debenture funds. Lock that in and your occupancy cost stops moving for decades.
The constraints are genuine, though. You have to occupy 51% of an existing building or 60% of new construction, which rules out anyone buying property as an investment. Equipment needs at least ten years of useful life left in it. Your contribution rises to 15% for special-purpose properties like hotels, gas stations and car washes, or if the business is under two years old, and to 20% if both are true. There’s also a job creation test, currently one job created or retained for every $95,000 of debenture.
One detail that catches people out: only the CDC piece carries the SBA guarantee. The bank’s half is conventional lending, underwritten to conventional standards, so you’re clearing two credit processes instead of one. Budget more time than you would for a 7(a).
Good fit: buying the building you already operate from, construction or major renovation, heavy machinery. Poor fit: working capital, inventory, goodwill, or anything you expect to refinance within five years.
The 7(a)
This is the SBA’s flagship program and the one that handles everything the 504 can’t. Maximum loan amount is $5 million, and the appeal is breadth. Working capital, acquisitions, partner buyouts, equipment, refinancing expensive debt, or a project blending several of those at once, all in a single facility.
The SBA guarantees up to 85% on loans under $150,000 and 75% above that, which is why pricing comes in well below Express. Rates are negotiated with the lender and may be fixed or variable, subject to SBA maximums. For variable-rate loans, the current maximum spread depends on loan size and ranges from base rate plus 6.5% for the smallest loans to base rate plus 3.0% for loans above $350,000. Terms can reach 10 years for working capital and acquisitions and 25 for real estate.
It’s also the only realistic route when there’s no hard asset behind the purchase. Buying a book of business, funding a management buyout, paying for goodwill in an acquisition. A 504 simply can’t be used for any of that.
Good fit: acquisitions, buyouts, expansion capital, mixed-purpose projects. Poor fit: a clean owner-occupied building purchase, where a 504 will usually beat it on both rate and cash required.
Express
Express tops out at $500,000 with a 50% SBA guarantee, and the SBA responds to the lender within 36 hours. It can be structured as a term loan or a revolving line of credit, running up to 10 years for working capital, equipment and inventory, or 25 years for real estate.
You pay for the speed. Express does not have a single standard rate premium. The lender negotiates pricing subject to applicable SBA maximums, and the lower 50% guaranty means lenders may price Express differently from a standard 7(a).
Two things worth being clear about. That 36 hours is the SBA’s turnaround to the lender, not money in your account, and funding still commonly takes 30 to 90 days. And since the credit call rests largely with the bank, outcomes differ more between lenders here than on any other program.
Good fit: a revolving line for seasonal cash flow, smaller equipment purchases, opportunities with a deadline attached. Poor fit: anything above $500,000, or debt you’ll carry for a decade while that rate premium compounds.
You can now use two at once
The old cumulative cap used to force a choice on bigger projects. Since July 2026, a 7(a) balance no longer eats into your 504 debenture maximum, and the combined ceiling is $10 million. A business buying a facility and funding the working capital to run it can now use both programs side by side instead of squeezing everything into one.
The lender matters as much as the program
Two banks running the identical 504 on the identical project will not give you the same experience. Preferred Lender status allows an institution to make the credit decision internally rather than sending it to the SBA, which often saves weeks. Volume helps too. A bank closing these every month knows exactly where files get stuck, and usually knows before you do.
The conversation worth having isn’t which program to apply for. It’s this: here’s what I’m buying, here’s when I need it, here’s what I can put in. Then let someone who works these programs daily tell you which one fits.
