Equity Injection and Seller Notes in an SBA Business Purchase

Two ideas drive the cash side of most acquisitions: how much of your own money goes in, and how the seller's financing is treated. The details changed with SOP 50 10 8.1, so confirm them before you negotiate.

Key facts

  • The "equity injection" is the cash and qualifying value the buyer puts into the deal. It's in addition to the loan.
  • The SBA minimum for a typical change of ownership is 10% of the total project cost.
  • A seller note can sometimes count toward that, if it is on full standby and within the program's limits.
  • Seller notes that are not on standby don't count toward the injection, but their payments do count against your cash flow.
  • Everything numeric on this page comes from secondary sources and should be verified against the current SOP.

Written for larger, structured projects: acquisitions, owner-occupied real estate and expansion. For quick capital or small short-term needs, your local SBDC or a nonprofit lender is usually a better first call.

Two different kinds of “skin in the game”

Lenders want the buyer to have real money in the deal. They want the seller to stay interested in the business’s success, too. In an SBA acquisition, those two ideas show up as the equity injection and the seller note.

Equity injection, in plain terms

The equity injection is the portion of the total project cost that comes from you, not from the loan. It’s most often cash, and it must be documented: lenders want to see where it came from.

For a change of ownership, the minimum under the current rules is 10% of the total project cost, and the total project includes more than the price: closing costs, fees, and working capital. (When an established business buys another in its industry, or in some partner buyouts, the lender can reduce or waive it.) That detail matters when you’re planning how much cash you need.

Seller notes, in plain terms

A seller note means the seller finances part of the price and you repay them over time. Its effect on your deal depends on how it’s structured.

  • A standby seller note is one on which the seller agrees to wait: no payments of principal or interest for the full term of the SBA loan (interest can build up and be paid afterward). Because it doesn’t draw on your cash flow while the SBA loan is outstanding, it can count toward your required equity.
  • A regular seller note, with payments starting right away, is still real financing and often helpful, but it doesn’t count toward the injection. Its payments get added to the debt your cash flow must cover.

There’s a limit on this. SOP 50 10 8.1 caps the share of the required injection that can come from a standby seller note and certain other sources that aren’t your own cash (such as a small, non-controlling outside investor) at no more than half. The point of a cap is that the buyer must still bring real cash.

Hypothetical example

Total project: $1,150,000 (price $1,000,000, closing costs $50,000, working capital $100,000).

  • Required injection at 10%: $115,000.
  • Buyer brings $57,500 in cash.
  • Seller carries a $57,500 note on full standby, which, under the half cap, can cover the rest of the injection.
  • The SBA-backed loan is the remaining $1,035,000.

At an assumed 10% rate over 10 years, that loan’s payment is roughly $13,700 a month, or about $164,000 a year. The seller’s standby note adds nothing to that while it’s on standby. If the seller instead insisted on a regular $200,000 note with payments, it wouldn’t count toward the injection, the buyer would need more cash, and the note’s payments would add to the debt service. These numbers are invented to show how the pieces move.

Questions to settle before the letter of intent

Terms are far easier to shape before a price and structure are agreed. Ask:

  1. What is the total project cost, not only the price?
  2. How much cash can I put in and show a source for?
  3. Will the seller consider a note, and on what terms: standby or paying?
  4. Does the structure rely on contingent payments, like earnouts or performance-based price adjustments? (Seller earnouts are not allowed under SOP 50 10 8.1.)
  5. What’s the monthly cost of every piece, and does the cash flow cover it? See DSCR in plain English.

Tradeoffs worth saying out loud

  • A seller note lowers your cash need, but it’s still debt. A standby note feels free until the standby period ends or the SBA loan is paid off.
  • More cash in makes deals sturdier. It’s tempting to minimize cash, but a thin cushion is where small surprises become big ones.
  • The seller’s incentives matter. A seller who stays on the hook has a reason to help you succeed in the transition.

What to verify

SOP 50 10 8.1 changed parts of this. Everything flagged on this page comes from secondary sources and our own reading, and should be checked against the SOP and your lender’s current policy. Your lender can tell you how they apply it to your deal.

Common questions

What does "full standby" mean?

It means the seller agrees to receive no payments on the note, neither principal nor interest, for the full term of the SBA loan, and that the note is subordinate to the SBA loan. Interest can accrue and be paid after the SBA loan is repaid. The point is that a standby note doesn't compete with the SBA loan for your cash flow. The exact definition is in the SOP and the lender's documents.

Can I borrow my down payment?

Lenders look closely at where your cash comes from. Borrowed funds, gifts and funds from other parties get more scrutiny and may be limited or have conditions. Ask a lender before you arrange them, not after.

Is a seller note a good idea?

Often it's useful: it lowers the cash you need, and it keeps the seller invested in a smooth transition. But it's still debt, and it needs to fit your cash flow. It's a tool, not a magic fix.

Why are earnouts a problem?

A payment to the seller that depends on future performance makes the price uncertain, which complicates the lender's analysis. SOP 50 10 8.1 prohibits seller earnouts in SBA-financed purchases. Check the current rule if you're considering one.
