Down payment is usually the first question anyone asks when they start looking at buying a business — and the answer for SBA 7(a) financing is meaningfully better than most people expect coming from real estate or conventional business lending.
The typical range: 10–15%
SBA 7(a) loans for business acquisitions generally require 10–15% equity injection from the buyer, depending on the lender, the deal's cash flow strength, and whether the seller is willing to carry a note. This is dramatically lower than the 25%+ down payments standard in commercial real estate lending, or the 20–30% many conventional business lenders require without an SBA guarantee.
On a $500,000 HVAC business acquisition at 12.5% down, that's a $62,500 cash requirement from the buyer, financing $437,500 through the SBA loan.
Where the down payment can come from
- Buyer's own cash. Savings, retirement rollovers (ROBS structures), or home equity.
- Seller notes. Many SBA lenders allow a portion of the required equity injection to come from a seller note on full standby (no payments during the SBA loan term), effectively reducing the buyer's out-of-pocket cash.
- Gifted or partner equity. Family gifts or a minority equity partner can supplement the buyer's own contribution, subject to lender documentation requirements.
Why HVAC businesses qualify well
SBA lenders favor these businesses for a reason: consistent, often recurring revenue (service contracts, maintenance agreements), tangible collateral (vehicles, equipment), and an established track record most trades businesses have by the time they're listed for sale. That combination is exactly what supports the lower end of the down payment range and faster underwriting timelines relative to less standardized industries.
Down payment isn't the whole cash requirement
Buyers should budget beyond the down payment itself for: SBA guarantee fees (typically financed into the loan but sometimes required upfront), closing costs, and working capital to cover payroll and operating expenses through the transition period. A deal that clears on down payment alone can still leave a buyer undercapitalized in the first 90 days.
Down payment is only half the underwriting question. The other half is whether the business's cash flow actually covers the resulting loan payment — see our DSCR guide for that math, run automatically on every listing on Bizvetting.
