Business Acquisition Financing: Buy With Its Own Cash Flow

How acquisitions of shops, lots and routes actually get financed: SBA structures, seller notes, down payments - and reading a target's books like a lender.

Buying an existing business is the most leveraged legal wealth move available to an operator: the target's own cash flow services the debt that buys it. A repair shop netting $180K can be bought with ~$50-100K down, financed across 10 years, and pay for itself while paying you. The catch is that lenders know exactly how this works - and underwrite accordingly.

The standard acquisition stack

A $600K shop acquisition might look like: $420K SBA, $90K seller note, $90K down - with a $50K line opened at closing for the transition quarter. Total monthly debt service around $6K against the shop's $15K net: the deal breathes.

Read the target like the lender will

  • SDE quality: how much of 'seller's discretionary earnings' is real vs. add-back creativity? Lenders recompute it; so should you.
  • Customer concentration: one fleet account at 45% of revenue is a risk you're buying - price it in or contract it up.
  • What leaves with the seller: relationships, certifications, the license the whole model rests on. Transition terms belong in the purchase agreement.
  • Equipment reality: that 'included' lift list at book value - inspect it like you're buying it, because you are.

The seller note is your alignment tool

A seller carrying 15% on standby has 15% worth of reasons to make the transition succeed - introductions made, quirks explained, phone answered in month three. All-cash exits walk away clean. Negotiate the note even when you don't need the money.

FAQ

How much down payment do I need to buy a business?+

SBA-financed deals: typically 10-15% from you, sometimes partially covered by a seller note on standby. A $500K acquisition realistically wants $50-75K of your capital plus closing costs and a working capital cushion.

Can I buy a business with bad personal credit?+

SBA routes get hard below ~650. Alternatives: bigger seller financing (sellers underwrite trust, not FICO), asset-based structures against the target's equipment, or a creditworthy partner. Fix what's fixable first - acquisition debt is cheap only when your file is clean.
