What is an SBA 504 loan and how much down payment does it require?

An SBA 504 loan is a government-backed program that lets owner-occupant practices buy their building with about 10% down, versus 20–25% conventional.

An SBA 504 loan is a U.S. Small Business Administration program that provides long-term, fixed-rate financing for owner-occupied commercial real estate.

Its biggest advantage is the down payment: typically around 10% of the project cost, compared with 20–25% for a conventional commercial loan. On a $2,000,000 building, that can be the difference between roughly $200,000 and $400,000 in cash at closing — capital a practice can keep in the business instead. The program requires your business to occupy at least 51% of the building, which fits the owner-occupied model and even allows you to lease out the remaining space. The SBA portion carries a long fixed rate, protecting against interest rate swings. There are fees and early prepayment penalties to weigh, so the right comparison is total cost over how long you plan to hold the building.
