Seller Financing Explained (for Business Buyers)

Seller financing is the single most useful tool for buying a small business with less cash. Instead of paying everything up front, the seller carries a note — and that changes everything about the deal.

The mechanics

You pay a down payment, then make monthly payments on a promissory note for the remaining balance, at an agreed interest rate over a set term. The payment is a standard amortizing loan, identical to a mortgage:

M = P · r · (1 + r)^n / ((1 + r)^n − 1)

where P is the financed amount, r is the monthly rate (APR ÷ 12), and n is the number of monthly payments.

A worked example

That $400,000 note at 7% over 7 years costs roughly $6,037/month and about $107,000 in total interest. Run your own numbers — and see the full amortization schedule — in the seller-financing calculator.

Why buyers love it

It lowers your cash-to-close, speeds up the deal (no bank underwriting on the seller's portion), and — most importantly — keeps the seller financially invested in a smooth transition. A seller willing to carry paper is signaling confidence in the business.

Why sellers agree

Seller financing widens the buyer pool, can command a higher sale price, and spreads the seller's tax hit over years. Many motivated, retiring owners prefer steady note income to a lump sum.
