How an SBA 504 loan is structured

A 7(a) loan is one lender taking one risk under one SBA guaranty. A 504 loan is two lenders splitting a purchase into two liens, each priced for the risk each one holds, with the borrower’s equity absorbing the rest. That structure is why 504 usually beats 7(a) on rate for a real estate or equipment purchase, and why it is the wrong tool for almost anything else.

A bank funds the first mortgage, roughly half the project, and holds first position if the deal goes bad. A Certified Development Company, a nonprofit licensed by the SBA to run the program locally, funds a second-lien debenture up to 40 percent, carrying the SBA’s guaranty and a rate fixed for the debenture’s full term. The borrower funds the remainder, usually 10 percent, in cash or another eligible source.

Nobody negotiates that split loan by loan. It comes from the regulation, and a CDC applies it the same way on every project that qualifies.

The bank prices its own risk, and the CDC prices the SBA’s

The bank’s first mortgage is priced like any commercial real estate loan at that lien position: competitively, and independent of the SBA. The CDC debenture is where the program’s rate advantage lives. It is priced off an increment above the 10-year Treasury note, fixed for the debenture’s full term rather than resetting with the market, and the SBA-related cost built into that spread runs around 3 percent of the debt on top of the Treasury base. A borrower comparing 504 against a conventional loan should compare the blended rate across both liens rather than the CDC piece by itself.

Debentures run 10, 20, or 25 years. The 25-year term is the newer option, available since 2018, and it is the one to ask about on a purchase where stretching the amortization matters more than paying the debenture off early. The 504 blended-rate calculator splits a project across both liens and adds the two payments together once you have rates from each lender.

Equity climbs with risk, not with negotiation

Ten percent is the standard floor, and it rises on two conditions a CDC checks mechanically rather than judges deal by deal. A business that has operated two years or less raises the requirement to 15 percent. A project built around a special-purpose property, one with limited alternative use, does the same. Both conditions together raise it to 20 percent. A startup buying a purpose-built facility sits at the top of that scale and should plan for it rather than discover it at term sheet stage.

The maximum runs higher for manufacturers

A standard 504 project caps the CDC debenture at $5 million. Small manufacturers, businesses with a primary NAICS code in the 31 through 33 range and production based in the United States, and certain qualifying energy-efficient or public-policy projects, can reach $5.5 million in CDC funding instead. The bank’s first-mortgage share is not capped the same way, so total project size can run well above the debenture figure alone.

Fees ride on top of the two liens

The CDC charges its own fee set, capped by regulation rather than left to negotiation: a processing fee up to 1.5 percent of net debenture proceeds, an annual servicing fee between roughly 0.6 and 2 percent of the unpaid balance, and smaller funding and assumption fees. SBA adds its own upfront guaranty fee and annual service fee on the debenture, both set fiscal year by fiscal year and both waived entirely for small manufacturers under the current schedule. Ask the CDC for the current fee sheet rather than assuming last year’s figures still apply; SBA revises them annually.

What the property has to be

Real estate financed through 504 has to be majority owner-occupied by the operating business, the same 51 percent threshold on an existing building and 60 percent on new construction that governs a 7(a) real estate purchase. A building bought to lease out to unrelated tenants does not qualify no matter how strong the borrower’s credit looks. SBA financing for owner-occupied commercial real estate covers the occupancy math and the lease-out limits in full.

What to settle before you call a lender

• Which asset the loan is funding. Real estate and long-lived equipment fit. Working capital, inventory, and goodwill do not, and belong in a companion 7(a) loan if the deal needs them.
• Time in business and the property type, since either one alone can push the equity requirement to 15 percent, and both together to 20.
• Whether the manufacturer threshold applies, since it changes both the debenture cap and the fee schedule.
• A CDC operating in your area. Coverage is regional, and not every CDC writes every project size.

If the asset fits and you are ready to move, tell us about the loan and we find the lender that fits it. No credit check to see your matches.

Limits

This covers the standard 504 structure. It does not cover the tax treatment of the equity contribution, which is a question for a CPA, and it does not substitute for the regulation itself. Every figure above is read from 13 CFR Part 120 and SBA’s current program description. SBA revises its fee schedule annually and its procedures on its own timeline, so confirm the current text before relying on any of it for a specific deal.

Summary

Two lenders, two liens, one guaranty on the smaller one. The bank prices its own risk on the first mortgage; the CDC debenture, fixed for 10, 20, or 25 years, is where the program’s rate advantage lives. Equity starts at 10 percent and climbs with a new business or a special-purpose property. It is built for real estate and long-lived equipment, and it is the wrong program for a deal that is not.
