The Dental Student Debt Challenge
The average dental school graduate carries approximately $300,000 in student debt. For dentists looking to buy a practice, this creates a unique financing challenge: you're adding a business loan on top of significant existing obligations. Understanding standard SBA loan requirements is the first step.
The good news: SBA lenders who specialize in dental practices are accustomed to this. Dental practices generate strong, predictable cash flow, and lenders know that practice ownership typically increases a dentist's earning power significantly compared to associate positions.
How Student Debt Affects Your DSCR
Debt Service Coverage Ratio (DSCR) is the primary metric lenders use to evaluate your loan application. It measures whether the practice generates enough cash flow to cover all debt payments.[1]
The formula for global DSCR with student debt:
Business DSC = Practice cash flow / Business debt payments (at least 1.25x on a purchase)
Global DSC = (Practice cash flow + other personal income) / (Business debt + Student loan + Other personal debt) (at least 1:1)
SBA floors under SOP 50 10 8.1. The business test uses the seller's historical results; lenders can set higher minimums.
Example: DSCR Impact of $285K Student Debt
| Scenario | Standard Repayment | Income-Driven |
|---|---|---|
| Student Loan Balance | $285,000 | $285,000 |
| Monthly Student Payment | $3,200 | $1,400 |
| Annual Student Debt Service | $38,400 | $16,800 |
| Annual SBA Payment | $72,000 | $72,000 |
| Total Debt Service | $110,400 | $88,800 |
| Cash Flow Needed, Business Test (1.25x of $72,000) | $90,000 | $90,000 |
| Cash Flow Needed, Global Test (1:1, before living costs) | $110,400 | $88,800 |
| Binding Hurdle | $110,400 (global) | $90,000 (business) |
Student debt doesn't touch the business test: the practice needs $90,000 of historical cash flow either way. It shows up in the global test. On standard repayment the global test is the harder one, at $110,400. Moving to IDR drops it to $88,800, so the business test becomes the binding one and your overall hurdle falls by $20,400, a significant difference that can make or break loan approval. Lenders also count your personal living costs in the global picture, so treat these figures as the floor, not the target.
Strategies for Managing Student Debt Impact
Income-Driven Repayment (IDR) Plans
IDR plans cap monthly payments based on your income, which can dramatically reduce the student loan portion of your global debt service. Most SBA lenders will use your actual IDR payment amount rather than the standard repayment amount. The right loan program (504 vs. 7a) also affects your monthly payment structure.
- SAVE/PAYE/REPAYE: Payment capped at percentage of discretionary income
- IBR: Payment capped at 10-15% of discretionary income
- Key benefit: Lower monthly payment = lower global debt service = better global coverage
Don't Deplete Cash for Student Debt Paydown
It may be tempting to pay down student debt before applying for an SBA loan. But cash used for student debt paydown is cash you can't use for your 10% equity injection. In most cases, keeping cash for your down payment and using IDR plans is the better strategy.
Target Higher-Producing Practices
With significant student debt, your practice needs to clear two bars: 1.25x on the business debt, and 1:1 on a global basis once your student loans are added. This may mean targeting practices with higher collections rather than the smallest available practice. A practice collecting $700,000+ annually is more likely to support your combined debt load.
Seller Standby Notes
Seller financing on full standby reduces your cash needed at closing, preserving capital that might otherwise go toward student debt paydown. Full standby means no principal and no interest payments for the term of the 7(a) loan, which keeps the seller note out of your debt service entirely. Note the limit: full-standby seller debt and minority (under 20%) investor equity together can cover no more than half of the required injection, so the rest still has to come from you.[2]
What Lenders Ask About Student Debt
Be prepared to discuss:
- Total student loan balance and monthly payment amount
- Current repayment plan (standard vs. income-driven)
- Whether you plan to change repayment plans
- Any other personal debt (car loans, credit cards)
- Your projected personal income from the practice after acquisition
