SBA Loan to Buy a Business: How Lenders Size the Deal

Updated October 22, 2026 · Deal Readout research

Most buyers of small businesses in the U.S. finance the purchase with an SBA 7(a) loan. The SBA guarantees part of the loan, so banks lend against a business’s cash flow instead of requiring hard collateral for the full amount. The lender’s central question is simple: can the business’s cash flow pay the loan, with room to spare? Everything else follows from that.

SBA rules change. Confirm the current SOP and rate caps with your lender.

How lenders decide: debt service coverage

The lender takes the business’s cash flow available for debt and divides it by the annual payments on all debt. That is the debt service coverage ratio (DSCR). SBA sets a minimum, and many lenders want 1.25 or more. Cash flow means verified earnings after a reasonable salary for whoever runs the business.

Worked example

A laundromat with $205,900 of verified SDE is for sale at $650,000. The buyer puts 10% down and borrows the rest over 10 years at an assumed 10.25%.

Buyer equity (10%)$65,000
SBA loan$585,000
Monthly payment$7,812
Annual debt service$93,744
SDE minus a $55,000 manager$150,900
DSCR with a manager1.61x
DSCR if the buyer runs it (no manager)2.20x
Largest loan at 1.50x DSCR (with manager)$627,782

The deal passes. Now suppose the listing’s SDE was used instead and two add-backs turn out to be false. Every dollar of SDE that disappears comes straight out of the coverage. This is why lenders rebuild SDE from tax returns, and why you should do it before they do.

What lenders ask for

  1. Three years of business tax returns and interim financials.
  2. The purchase agreement or LOI and a sources-and-uses table.
  3. Your personal financial statement (SBA Form 413), tax returns, and resume.
  4. A business plan and projections that tie to historical numbers.
  5. The lease, and evidence it covers the loan term or can be extended.
  6. A business valuation when the deal requires one.

FAQ

How much down payment do I need to buy a business with an SBA loan?

At least 10% of the project cost under current SBA rules. A seller note on full standby can cover up to half of that 10%.

Can I buy a business with an SBA loan and no money?

Not under current rules: the buyer must inject equity. Some buyers combine their own cash with a standby seller note; see seller financing a business.
