SBA 504 vs conventional for owner-occupied property

There is a meaningful divide in commercial real estate finance between owner-occupied property — real estate a business buys to operate from — and pure investment property. Owner-occupants get options investors don't, and the most important is the SBA 504 loan. If your company is buying its own building, the choice between an SBA 504 and a conventional mortgage is worth understanding carefully, because the two structures serve very different priorities.

What the SBA 504 program is

The SBA 504 loan is designed for owner-occupied commercial real estate and major fixed assets. Its signature feature is a low down payment: typically about 10%, rising to 15% for startups or special-use properties. It funds through a distinctive 50/40/10 structure — a conventional lender provides 50% of the project, a Certified Development Company (backed by the SBA) provides 40%, and the borrower contributes 10%. Maximum project loans run up to roughly $5.5 million, terms extend up to 25 years, and the program requires that the business occupy at least 51% of the property.

That occupancy rule is the heart of it. The 504 program exists to help businesses own their premises, not to finance landlords — which is why the operating company has to actually use the majority of the space.

What conventional owner-occupied financing offers

A conventional owner-occupied mortgage skips the government program entirely. Because the occupying business is a second source of repayment alongside the real estate, lenders can be generous on leverage — conventional owner-occupied loans run up to about 90% LTV, at rates currently around 6.5%. For comparison, the SBA 504 prices lower, around 5.9%. So the conventional route can match the program on leverage while the 504 tends to win on rate.

How to actually choose

The decision usually comes down to two priorities: preserving cash versus preserving speed and simplicity.

• Choose SBA 504 when keeping cash in the business matters most. A roughly 10% down payment and a lower rate free up working capital — powerful for a growing company that would rather deploy cash into operations than into a building.
• Choose conventional when speed, flexibility, or a non-qualifying situation rules the day. Conventional financing avoids the program's eligibility requirements and additional process, can reach comparable leverage, and gives the borrower a more direct path to close.
• Watch the occupancy line. If the business will use less than 51% of the property, the 504 is off the table and conventional is the answer by default.

The takeaway

For an owner-occupant, the SBA 504 is a genuinely powerful tool — low down payment, long term, attractive rate — when the business qualifies and can accept the program's structure. Conventional financing trades a bit of that pricing advantage for simplicity, comparable leverage, and control of the timeline. Neither is universally better. The right answer depends on whether your scarcest resource is cash or time — and on whether your business will truly occupy the building it's buying.
