For a first-time buyer, the maximum dental practice loan amount comes down to three tests: how the loan compares to the practice’s annual collections, whether cash flow can cover all your debt, and how strong you are as a borrower. Of the three, profitability carries the most weight.
Understanding how lenders apply these tests helps you target the right practices, size your offer realistically, and avoid underwriting surprises.
Loan-to-gross: how practice revenue sets the ceiling
Loan-to-gross (LTG) compares the total acquisition loan to the practice’s annual gross collections. A $900,000 loan on a practice collecting $1 million a year is a 90% LTG.
| LTG ratio | How lenders typically view it |
|---|---|
| 75–85% | Preferred range for most deals |
| 85–100% | Possible with solid cash flow and a qualified buyer |
| 100–110% | Reserved for premier practices with exceptional profitability and financially strong buyers |

For a buyer without prior ownership experience, practice revenue effectively sets the loan’s upper limit. A $1.2 million practice at an 80% LTG points to roughly $960,000 in financing. LTG is a ceiling, not a guarantee: lenders weigh it alongside cash flow, debt service coverage, and your personal finances.
Debt service coverage: can the practice carry all your debt?
Banks generally require a debt service coverage ratio (DSCR) of at least 1.2x. For every $1.00 of annual debt payments, they want at least $1.20 of income available to cover it.
DSCR = Cash flow available for debt service ÷ Total annual debt payments (target: 1.2 or higher)
The debt side of that equation is broader than the practice loan. Lenders add your existing personal obligations, including student loans, car loans, and your mortgage. If your combined annual payments total $100,000, the bank will generally want to see at least $120,000 in annual cash flow to service them.
Cash flow beats personal assets
Approvals often come in higher or lower than buyers expect because conventional banks underwrite based on actual cash flow, not the size of your personal balance sheet. Lenders look at both the top and bottom line, but profitability matters most.
LTG sets a ceiling relative to collections. Cash flow determines how close you get to that ceiling. A highly profitable practice can support a larger loan for a buyer with modest savings, while a high-revenue practice with thin margins may cap the loan below what its collections suggest, especially once you factor in personal debt.
Reading between the lines: the 35% benchmark
A good rule of thumb is to target practices producing at least 35% of net collections in normalized owner cash flow, also called Owner’s True Net Income or EBITDA. On $1 million in collections, that means at least $350,000.
Don’t judge a practice by its tax return alone. Taxable income and actual cash flow are very different numbers. Owners legitimately deduct expenses that shrink reported profit, so a return can show margins well below 35% while the underlying cash flow is much stronger.
To find true earning potential, add back expenses that won’t carry over to a new owner:
- Owner compensation
- Depreciation and amortization (noncash)
- Interest expense and other financing costs
- Discretionary owner expenses such as vehicles, travel, and meals
- One-time or nonrecurring costs
For an owner-operator, these adjustments often reveal significantly more cash flow than the return suggests. Normalized cash flow is the number to focus on, and lenders use it to judge whether the practice can comfortably service the acquisition debt alongside your other obligations.
Should you finance 100% or put cash down?
For dental practice acquisitions, banks typically require borrowers to demonstrate liquidity equal to 10% of the total loan amount during the loan approval process. Qualifying assets generally include cash, savings, and readily marketable stocks, but typically exclude retirement accounts such as 401(k) plans. This is not a down payment requirement. You simply need to show the bank that you have sufficient financial reserves available for unexpected expenses.
For example, if you plan to borrow $1 million, you should be prepared to demonstrate at least $100,000 in liquid assets. For qualified buyers, financing 100% of the purchase price plus working capital is common, and a down payment generally isn’t required. A financially healthy practice should generate enough cash flow to cover its loan payments comfortably while still paying the owner a high income.
Important: If you are also purchasing the practice’s real estate, be prepared for a separate down payment. Requirements vary by financing type:
- Small Business Administration (SBA) Loans: Can require as little as 10% down.
- Conventional Commercial Real Estate Loans: Typically require 20% or more down.
Actual down payment requirements depend on the lender, borrower, and property.
Putting it together
- Start with collections. Expect lenders to cap most loans at 75–85% of annual collections, with up to 100–110% possible for premier practices and strong buyers.
- Count all your debt. Plan for a DSCR of at least 1.2x across the practice loan and your personal obligations.
- Look past the tax return. Normalize cash flow and aim for at least 35% of net collections in true owner earnings.
- Protect your liquidity. If you qualify, 100% financing with working capital can keep savings available for the unexpected.
The practices that earn the best financing terms have strong, sustainable cash flow, so evaluate profitability first and price second.
