How SBA 7(a) financing works for acquisitions

For most people buying a service business in the US, the SBA 7(a) program is the path. It funds up to $5M, stretches repayment over ten years (twenty-five if real estate is in the deal), and asks the buyer to put in at least 10% equity, up to half of which a seller can supply through a note held on full standby.

What a lender is checking

  • Coverage of at least 1.25x after a fair-market salary for the buyer is taken out of earnings.
  • Three years of business returns plus current interim financials.
  • The buyer's credit, relevant experience, and cash on hand. Scores around 680 and up are typical.
  • A clean license handoff, which matters most in HVAC, plumbing, and electrical.

Typical deal structures

A common stack is 10% buyer cash, a 10% standby seller note, and 80% from the SBA loan. On stronger files, lenders will go to 5% cash plus a 5% seller note. Either way, always fold the seller note into your coverage math. It's the line buyers most often leave out and then regret.
