Buying a Dental Practice: How Acquisition Financing Works and What Lenders Require

By MercFinancial · Published 2026-10-22 · Updated 2026-10-21

A dental practice acquisition loan is sized to the seller's collections and cash flow, and practice lenders commonly finance the full price for a strong buyer. What the valuation, the transition and the debt-service math look like.

Financing the purchase of a dental practice works differently from most business acquisitions: practice lenders commonly finance the full purchase price, and often working capital on top of it, because they underwrite the seller's collections and cash flow rather than the resale value of the chairs. SBA 7(a) lenders write the same deals at long terms with an owner equity expectation, and when the building comes with the practice, SBA 504 and commercial real estate lenders join the file.

This guide covers how a dental practice is valued and how the loan is sized, what lenders weigh in an acquisition, the capital that exists for a buyer, the acquisition file step by step, an illustrative debt-service calculation, the mistakes that get dental acquisition files declined, and how a brokerage compares offers across the funding sources whose policy fits the deal, whether you are an associate buying a first practice or an owner adding a second.

In short

A dental practice acquisition loan is commonly sized to the seller's trailing collections and the cash flow left after the buyer's compensation, not to hard collateral.
Many practice lenders finance a strong dental practice purchase at or near the full price, often with working capital included, a convention specific to practice lending.
Lenders read a dental acquisition on collection trends, hygiene mix, payer mix, staff retention and the seller's transition commitment.
SBA 7(a) loans are available for a dental practice purchase subject to the lender's credit policy, and the building can be financed alongside the practice.

A lender buys the seller's collections report on the buyer's credit, and the transition agreement is what holds the two together.

What lenders like about a dental practice acquisition, and what they weigh

An acquisition is the file practice lenders like best, because the thing being financed already produces the cash that repays the loan. The seller's collections and overhead are known, the patients are on recall and the staff are in place, so the underwriter is not guessing at a ramp, and the goodwill is unusually durable because patients tend to stay through a well-managed transition. That is why high-percentage financing is routine in dental practice loans generally and in acquisitions in particular.

What the underwriter weighs on an acquisition:

Collection trends: three years of collections, flat or rising, with a clear explanation for any dip.
Hygiene mix and recall: a healthy share of production from hygiene signals a returning patient base that will survive the handover.
Payer mix: a practice heavy in one PPO or in Medicaid carries reimbursement and write-off risk the lender will price.
Procedure mix against the buyer's skills: if the seller places implants and the buyer does not, that production leaves the forecast.
Staff and the seller's transition: who stays, for how long, and whether the seller works back under a written agreement.
The buyer: production history as an associate, credit, liquidity and student debt service.
The lease or the building: assignability, term against the loan, or the appraisal if the building is in the purchase.

How a dental practice is valued and how the loan is sized

Dental practices are valued by brokers and appraisers on some combination of collections and earnings. A common shorthand expresses price as a share of trailing collections, and a more careful approach capitalizes earnings before owner compensation with the seller's discretionary expenses added back. Lenders look at both but lend on the second: the cash flow left after the buyer takes a reasonable salary, pays the staff, lab, supplies and rent, and services the new debt.

The loan is sized so that this remaining cash flow covers the annual debt service with a cushion. Lenders express the cushion as a debt service coverage ratio and set a minimum in their credit policy, and that minimum decides whether a price is financeable rather than merely agreed. Working capital is commonly added so the buyer is not starting with an empty operating account while the first claims are paid.

Why the valuation matters to the lender

A lender will usually order or review an independent valuation. A price above what the cash flow supports is resized rather than declined, and the buyer renegotiates, brings cash, or asks the seller to carry part of the price on a note.

The acquisition capital that exists for a dental buyer

Practice acquisition loans from specialty lenders. The main route. Long terms, high-percentage financing on a strong file, working capital built in, and underwriting that understands a hygiene report.
SBA 7(a) loans through banks and non-bank SBA lenders. Dental practices are eligible subject to the lender's credit policy. The SBA guaranty lets a non-specialist lender write the deal at a long term, usually with an owner equity expectation on a change of ownership, personal guaranties and more paperwork. A seller note may count toward part of that equity under the lender's rules.
Conventional bank loans for buyers with a banking relationship, liquidity and a practice whose cash flow sits comfortably above the bank's minimum coverage.
Seller financing for part of the price, usually subordinate to the main loan. It aligns the seller with the transition and can bridge a valuation gap.
Real estate loans, including SBA 504, when the building is in the deal. The general mechanics are in business acquisition financing options and the SBA loan requirements checklist.

Which route is available depends on the funding source. A brokerage that reads practice files can show the same deal to several lenders and compare business funding structures on the whole cost, not only the rate.

How long each stage of a financed dental practice purchase commonly takes, in days, from a signed letter of intent

The dental acquisition file, step by step

Letter of intent and the seller's package

The signed letter of intent, three years of practice tax returns and profit and loss statements, year-to-date interims, and production and collections reports by provider, procedure and payer.

The valuation

A broker or appraiser's practice valuation, or the lender's own review. A chart audit or equipment list often accompanies it.

The buyer

License, CV, associate production history with W-2s or 1099s, two or three years of personal tax returns, a personal financial statement, a credit report and a schedule of student loan payments.

The transition and the premises

The seller's transition agreement with its working-back period, staff retention plans, the lease assignment or new lease, or the purchase contract and appraisal if the building is included.

Sources and uses

A schedule of the price, working capital, closing costs, any equipment refresh and the buyer's cash, with the lender's debt-service test shown on the buyer's projected cash flow.

Illustrative example: the debt-service math on a practice purchase

Illustrative example: a hypothetical general practice collects $1,200,000 a year with overhead of $720,000 before the owner's pay, leaving $480,000. The buyer is offered the practice for $840,000 and wants $60,000 of working capital, a hypothetical loan of $900,000. The lender subtracts a reasonable owner salary, say $240,000, which leaves $240,000 to service debt. If the annual payment on a ten-year loan were around $115,000, the cushion would be roughly two to one, comfortably above what many practice lenders require. These figures are round and invented, and the lender's actual rate, term and coverage minimum decide the real answer.

Line	Illustrative figure	What the lender does with it
Collections	$1,200,000	Checked against three years of reports and the payer mix
Overhead before owner pay	$720,000	Compared with the lender's dental benchmarks
Buyer's salary	$240,000	Deducted so the practice is tested on cash left after a living
Cash flow for debt service	$240,000	Divided by annual debt service for the coverage ratio
Annual debt service	about $115,000	Set by the lender's rate and term on $900,000

Mistakes that get dental acquisition files declined

Agreeing a price before the cash flow is tested. A price set on a rule of thumb can exceed what the practice supports after the buyer's salary and debt service.
Ignoring procedure mix. A buyer who will refer out the seller's specialty work must show the forecast without it.
No written transition. A seller who leaves on closing day with no working-back period is a risk every lender prices or declines.
A lease that cannot be assigned, or that ends before the loan. Landlord consent and term are checked early by every practice lender.
Thin liquidity after closing. Lenders want the buyer to keep some personal cash and a working-capital reserve.
Undisclosed debt. Student loans or a prior practice loan that appears on the credit report but not on the personal financial statement.
Letting the seller's numbers drift. A seller who cuts hours before closing hands the buyer a smaller practice than the one underwritten.

Frequently Asked Questions

Can I get 100 percent financing to buy a dental practice?

Commonly, yes, for a strong file. Many practice lenders finance a dental practice purchase at or near the full price, often with working capital added, because they underwrite the seller's collections and cash flow rather than collateral. SBA lenders usually expect some owner equity on a change of ownership, which a seller note may help meet. The funding source sets the percentage.

How is a dental practice valued for a loan?

Brokers and appraisers value a dental practice on collections and earnings, often quoting price as a share of trailing collections and checking it against capitalized earnings after the seller's add-backs. Lenders test the price against the cash flow left after the buyer's salary and overhead, and size the loan so that cash flow covers the debt service with a cushion set by their credit policy.

Can I use an SBA loan to buy a dental practice?

Yes. Dental practices are not excluded by 13 CFR 120.110, so a 7(a) loan is available through any SBA lender whose credit policy accepts practice acquisitions. Expect an owner equity expectation, personal guaranties, a valuation, and a review of the lease or the building. The lender decides approval and terms.

What does a lender want to see from the seller?

Three years of practice tax returns and profit and loss statements, year-to-date interims, production and collections reports by provider and procedure, receivables aging by payer, active patient and hygiene recall counts, a staff list with tenure, the lease, an equipment list and a written transition agreement saying how long the seller will work back.

Does the seller need to stay after closing?

Lenders strongly prefer it, and many require a defined transition period in writing. The seller's working-back period, a letter to patients and an introduction to referring dentists protect the collections the loan is built on. A seller who exits on closing day with no transition makes the file harder to place and can lead to a smaller loan or a decline.
