Buying a dental practice with student loans

Most dentists who buy a practice still owe on dental school. Practice lenders see it every day and expect it.

Ownership is coming later, though. Early in their careers, 21% of 2016–20 graduates owned a practice, per ADA Health Policy Institute data. For those who graduated in 2010 or earlier, it was 63% to 70%. HPI lists rising educational debt as one possible reason, and notes most dentists still become owners eventually.

How practice lenders look at your student debt

The ADA’s guide to practice loans says it directly: “Student loan debt doesn’t prevent you from getting a business loan.” What lenders ask about instead, per the ADA:

• Do you have a solid credit history, and are your finances in good shape for an acquisition?
• The practice’s history, patient base, staffing and financial information.
• Your timeline, and what debt you need: acquisition loan, line of credit, real estate.
• Whether the seller will stay on to help with the transition.

The ADA adds that a bank confident in a smooth cash-flow transition is more likely to lend against the practice’s full value. In other words, the practice’s cash flow does most of the work.

Your student loans show up in two places. They’re part of your credit history, so a clean payment record matters. And your monthly payment is part of what you need to live on. That comes out of the practice’s cash flow too.

Lenders don’t publish a single debt-to-income cutoff for dentists. Ask each lender how it counts your student loan payment: the actual RAP payment, a percentage of the balance, or something else. The answer changes how much room you have.

SBA 7(a) basics (as of September 2026)

Many acquisitions use the SBA’s 7(a) program or a conventional loan from a dental specialist bank. Per sba.gov:

• The maximum 7(a) loan is $5 million. Uses include changes of ownership, equipment, working capital, real estate and refinancing business debt.
• Maturity is generally 10 years or less, and up to 25 years for real estate.
• You must show you can’t get the credit on reasonable terms from non-federal sources.

The SBA’s rulebook is changing. SOP 50 10 8.1 applies to loans given an SBA loan number on or after Oct. 1, 2026, and moves change-of-ownership rules into a new appendix (SBA Information Notice, Aug. 14, 2026).

Appendix 15 of the SOP sets the rules for an “initial acquisition.” That’s the default category: you become the new majority owner and haven’t worked at the practice for 24 months. For those deals:

• You need an equity injection of at least 10% of total project costs, which “cannot be reduced or eliminated.” Seller debt on full standby can cover up to half of it.
• Cash flow must cover the debt payments at least 1.25 times, based on the practice’s last year or last two years.
• At a purchase price of $3 million or more, the lender must get an independent quality-of-earnings report.
• The seller can’t stay on as an employee or owner. They can consult for up to 24 months.

Confirm the details with your own lender.

That 10% is cash you need at closing. It competes directly with paying down student loans, so plan for it a year or two out.

How RAP, PSLF and refinancing interact with buying

RAP. Your RAP payment is 1% to 10% of AGI, divided by 12 (10% above $100,000). Owners usually earn more than associates, so the payment rises. The upside is that it also falls if a bad year shows up on your tax return. That flexibility is worth the most in your first year of ownership.

PSLF. A dentist at a private practice doesn’t work for a qualifying employer, per Federal Student Aid. When you leave an FQHC, the VA or another qualifying job to buy, your count of qualifying payments stops growing. If you’re within a few years of 120, run the numbers before you sign. PSLF forgiveness is tax-free, and on a large balance it can exceed a year of ownership profit. See PSLF for dentists.

Refinancing. Refinancing turns federal loans into private ones. For those loans you lose access to RAP, PSLF, federal forgiveness, and federal forbearance and deferment. A refinanced payment is fixed no matter what the practice collects. For most buyers, refinancing is a decision for after the practice’s cash flow is proven, not before. See when refinancing is a mistake.

The math: an $800,000 practice, first year

Every number below is an assumption for illustration, not a benchmark. Swap in the figures from the practice you’re looking at.

• Practice: $1,000,000 in collections. Overhead before owner pay and loan payments: 65%, or $650,000.
• Purchase: $800,000. You put down 10% ($80,000) and borrow $720,000. (SBA’s 10% is of total project costs, so closing costs or working capital in the loan raise it.)
• Loan example: $720,000 at 8.0% fixed APR over 10 years is about $8,740 a month, $104,800 a year and $1.05 million in total. Example, not an offer; your rate depends on the lender, the deal and your credit.
• You: single, $300,000 in federal loans at 8.07%, on RAP. Your AGI last year as an associate was $180,000.

	Normal year	Collections down 15%
Collections	$1,000,000	$850,000
Overhead (assumed mostly fixed)	$650,000	$650,000
Cash flow before loan payments	$350,000	$200,000
Practice loan payments (example)	$104,800	$104,800
Left for you, before income tax	$245,200	$95,200

Lender’s view. Suppose the lender assumes you need $150,000 a year to live, student loan payment included. Cash flow left for the loan is $200,000, or about 1.9 times the $104,800 of payments. That clears a 1.25 minimum. In the down year, the same test gives about 0.5, which is why lenders ask about seller transitions and working capital.

Your student loan. On RAP, year one’s payment is based on your $180,000 associate income: $1,500 a month, or $18,000 a year. Compare the refinance example from our refinancing guide: $300,000 at 6.0% fixed APR over 10 years. That’s about $3,330 a month, or $40,000 a year (example, not an offer).

In the down year, that’s the difference between about $77,000 and $55,000 left before income tax. Once a good ownership year hits your return, RAP stays at 10% of a higher AGI. At an AGI of $245,000 that’s roughly $2,040 a month, close to the $2,020 of monthly interest on your student loans.

AGI for a new owner won’t match cash in hand. Depreciation and amortization from the purchase lower it; practice-loan principal isn’t deductible. A dental CPA can project yours.

Who this is right for, and who should wait

Buying with student debt usually works if the practice’s cash flow covers the loan comfortably. You also want clean credit, the 10% down payment and a cash cushion.

Waiting often makes more sense if:

• You’re a few years from PSLF forgiveness at a qualifying employer.
• The practice only clears 1.25 coverage under optimistic collections.
• The down payment would empty your emergency fund.
• You just refinanced and have no payment flexibility left.

What to do next

1. Get your student loan picture straight. Know your plan, payment and, if relevant, your PSLF count. See the RAP guide.
2. Talk to two or three practice lenders early. Ask how they count your student loan payment and what coverage they need. See dental practice loans explained.
3. Stress-test the deal. Rerun the table above with the practice’s real numbers and a 15% dip.
4. Hold off on refinancing until you’ve seen a year of ownership cash flow. Then run the numbers.
5. Set up the business side before day one. Read entity setup, then payroll and bookkeeping. Accounting software such as QuickBooks should be running before the first deposit.
