The idea of acquiring a business without putting any cash upfront is appealing to many buyers. But in practice, securing 100% seller financing is a rare scenario. With over 12 years of experience as an SBA lender, I’ve gained a deep understanding of what it takes to secure financing. During my time as the executive director of Bankable, I had the opportunity to approve more than 1,500 SBA loans across various industries. During those 12 years it was very, very rare to see an acquisition deal with seller financing anywhere close to 100%.
I saw a LinkedIn post by Clint Fiore that I thought was great. He’s an experienced business acquisitions expert who said the two easiest ways to get 100% seller financing is to either be way richer than the seller or be the child of the seller.
The first point is straightforward: if a buyer is much richer than the seller, the seller may feel comfortable offering 100% financing. The idea here is that the buyer's wealth acts as a personal guarantee, providing financial security. For example, if someone like Warren Buffett wanted to buy your business, you might agree to seller financing, trusting in his ability to pay, given his net worth of over $100 billion in 2024. However, you might also think: if the buyer is really rich, why not just pay upfront?
The second way to get 100% seller financing is through family ties. If the buyer is the seller’s child, there's more trust and flexibility in the financing terms. Sellers may want to keep the business in the family and help their child succeed without a big upfront payment, making it a natural part of succession planning.
For buyers who don’t fall into either of these categories, securing 100% seller financing is tough. Lenders and sellers usually want buyers to have "skin in the game,"—it means, they’ve invested their own money and are committed to the business's success. That's why SBA 7(a) loans, the most common way to finance buying a small business, require an equity injection of at least 10% of the total project cost, and lenders often ask for more.
The Closest Thing to 100% Financing with an SBA Loan
Under SBA SOP 50 10 8.1, which took effect October 1, 2026, at least half of the required 10% equity injection must come from your own “unlimited” sources: cash, a gift, or a personal loan repaid from outside the business. A seller note can cover the other half, but only if it is on full standby, meaning the seller receives no principal or interest payments for the entire term of the SBA loan, typically 10 years.
That means the lowest-cash structure for most SBA-financed acquisitions is:
- 90% SBA 7(a) loan
- 5% seller note on full standby
- 5% buyer cash
On a $1,000,000 purchase, that is $50,000 out of your pocket, not zero. And the lender still has to show the business’s historical cash flow covers the new debt at a 1.25x debt service coverage ratio. You can read more about how that works in our guide to SBA cash flow requirements and our guide to seller notes and SBA loans.
Each lender has its own rules, processes, and risk tolerance. If you don’t need a large loan, consider exploring lesser-known non-bank lenders, such as CDFIs (Community Development Financial Institutions) or SBA Microlenders, which might offer more flexible options.
Buying the Family Business?
If you are buying from a parent, seller financing can be more flexible, but SBA rules add a few wrinkles. When the buyer and seller have a close relationship, the SBA requires an independent business valuation prepared for the lender regardless of the purchase price, and in a standard acquisition the selling parent generally cannot stay on as an owner or employee after closing (a transition consulting agreement of up to 24 months is allowed).
The Role of Seller Financing in Business Deals
Seller financing helps close business deals but usually isn't the only source of funding. It often serves to bridge the gap between what a buyer can borrow and what a seller wants. It is common in small business sales, but it is generally combined with other sources like SBA loans or personal savings. Understanding this dynamic is key for both buyers and sellers. While 100% seller financing is appealing, it’s realistically most feasible in situations where the business is struggling to attract buyers, or when the seller is highly motivated to exit quickly due to personal circumstances like retirement or relocation. Outside of these situations, securing such terms can be quite challenging, as most sellers prefer some upfront payment to reduce their risk. It’s important for buyers to explore all financing options and understand what lenders prioritize when evaluating deals.
