Selling Your Dental Practice to an Associate? The SBA Loan Rules Just Changed

On October 1, the rules changed for the dentist most likely to buy your practice.

Not the DSO. The associate down the hall.

Most associates buy with an SBA loan, and that loan just got harder to get. If your plan is to sell to the doctor you trained, the bank now has a bigger say in your exit than you do.

Your most natural buyer may not get the loan

TUSK Practice Sales put it plainly in its Q4 2026 Dental Market Report (October 14): the associate in your practice "may be your most natural buyer and still be unable to finance a purchase."

Three things stacked up at once. The Fed raised rates on September 16. New SBA lending rules took effect October 1. And the class of 2025 left school carrying an average of $297,800 in education debt.

Two buyers, two ways to set a price

Sell to an associate and the price is usually set as a percent of collections, TUSK says. Sell to a DSO and it is set on EBITDA. TUSK's Q3 report put practice sales at 60 to 80% cash at close.

Now look at the associate side. TUSK runs an example it labels illustrative:

• A practice with $1.5 million in revenue, priced at 70% of revenue, sells for $1.05 million.
• Lenders increasingly expect the seller to carry 10 to 25% as a note.
• The buyer still has to borrow about $790,000 to $945,000.
• At close to 10% interest, a $900,000 loan over ten years runs about $11,900 a month.
• Add $300,000 of school debt and your buyer owes roughly $1.2 million before paying staff or rent.

Same practice. One buyer can write the check. The other needs the bank, and now needs you to lend part of the price.

What changed on October 1, in plain English

The SBA's new rulebook (SOP 50 10 8.1) applies to loans numbered on or after October 1. A lender's summary of the change-of-ownership rules:

1. Past cash flow has to cover the loan with room to spare. Your practice must show debt payments covered 1.25 times over, using last year or a two-year average. Projections do not count toward that test.
2. Every deal needs an independent valuation. That number caps the total debt. If the price is higher than the appraisal, the buyer brings more cash. (A broker or qualified appraiser does that work, not me.)
3. Deals of $3 million or more need a quality of earnings report. That is an outside accountant checking that your profit is real: books, tax returns, and bank deposits all have to match.
4. Your seller note may sit on standby. That means no payments to you, possibly for years, if it counts toward the buyer's down payment. Reports differ on how long, so ask the lender.
5. In a full sale, you generally have to leave. You can consult for up to 24 months. Sell only part of your practice, and the rules let you stay on as an owner.

Read that as the seller. Your associate buy-in now depends on how clean your books are, how long you can wait to be paid, and whether you are willing to walk out the door.

Many owners are counting on this path

Research I helped underwrite shows how common this plan is. Among business owners with a succession plan, 31.6% chose a self-funded internal succession and 11.4% an externally funded one (2024, n = 754). Among owners worth $5 million or more, the externally funded share was 13.5%.

For a dental buyer, outside money usually means an SBA loan. Those rules just tightened.

You have more than one path

TUSK lays out three: sell to an associate, sell to a DSO, or sell a stake and keep leading. Some owners now fold the associate into the DSO deal, giving them a partnership stake instead of a bank loan.

Each path changes your cash, your taxes, and your chair time. Your CPA sets the tax specifics for each one.

Bring these to your CPA, attorney, and lender:

1. Can my associate actually qualify under the new rules, based on my last two years of numbers?
2. How much would I have to carry as a note, and how long might I go without a payment?
3. If the appraisal comes in under our price, who covers the gap?
4. Are my books ready for a quality of earnings review today?
5. Would a partial sale let me stay, keep control, and still take money off the table?

What this means for you

The associate buy-in was the default exit for a generation of dentists. It still works. But it now runs through a lender who wants verified earnings, an outside valuation, and often a seller willing to wait.

If you are three to five years out with your associate quietly penciled in, or your numbers live half in QuickBooks and half in your head, this is for you. Clean books give you every path. Messy books leave you one.

Test the plan before it becomes a promise

The Dental Exit Stress Test is a complimentary 25-minute call. We look at your three paths side by side: what each one pays at close, what you keep after tax, and how long you stay in the chair. Book your 25-minute Exit Stress Test.

Who buys your practice if the bank says no?
