How to buy a dental practice: valuation, financing, and what to watch out for

I’ve been in this business long enough to have seen both sides of dental practice acquisitions — the ones that generate immediate cash flow and the ones where the buyer is calling me six months later wondering why the revenue is 30% below what the seller’s broker presented. The difference almost always comes down to the quality of due diligence, not the quality of the financing.

That said, financing matters too. Buying a dental practice is unlike buying most businesses because a significant portion of the value is goodwill — the patient relationships, the reputation, the referral network. Conventional business lenders often don’t know how to underwrite goodwill. Specialized dental lenders do, and choosing the right one can be the difference between a 45-day close and a 120-day ordeal.

Here’s what you need to know before you sign anything.

What is dental practice acquisition financing?

Dental practice acquisition financing is the lending structure used to purchase an existing dental practice from a selling dentist. It covers the purchase price, which includes tangible assets (equipment, supplies, furniture) and intangible assets (patient goodwill, practice name, phone number, trained staff).

In most dental acquisitions, goodwill represents 60–80% of the purchase price. That’s what makes dental practice loans a specialty category — most of the collateral doesn’t exist in a form a conventional lender can physically repossess. Specialized dental lenders are comfortable underwriting that goodwill because they understand that patient relationships generate predictable, recurring revenue. A general commercial lender looking at the same deal often sees a pile of intangibles and gets nervous.

This is distinct from dental equipment financing, which covers specific clinical assets. Practice acquisition loans cover the full transaction, including the goodwill premium that makes up most of the value.

How buying a dental practice works

The acquisition process typically moves through four stages: finding the practice, valuing it, conducting due diligence, and financing and closing. Each stage has its own landmines.

Finding the practice. Most dental practice sales are handled through practice brokers — ADS (American Dental Sales), Henry Schein Professional Practice Transitions, and independent regional brokers. Your state dental association often maintains a listing service as well. Off-market deals exist, particularly if you have a relationship with a dentist approaching retirement, but broker-listed practices are the primary market.

Valuing the practice. There are three valuation methods used in dental transactions. EBITDA multiples (typically 2–4x for GPs, 3–6x for specialty practices like orthodontics or oral surgery) reflect ongoing earning power. Collection-based valuation pegs the price at 50–80% of the trailing 12 months’ gross collections. Asset-based valuation totals the replacement cost of equipment and supplies — this is almost never used as a standalone method because it ignores goodwill entirely. Honest sellers and experienced buyers use EBITDA multiples as the primary method and collection-based as a sanity check.

Due diligence. This is where acquisitions succeed or fail. I’ll cover this in detail below.

Financing and closing. Once due diligence is complete and you have a signed letter of intent, your lender underwrites based on the practice financials, your credentials, and the transition plan. Specialized dental SBA lenders typically close in 45–60 days from complete application. For the mechanics of SBA financing specifically, our SBA dental loan guide covers the full process.

Why buying beats starting from scratch

A startup dental practice is a 24-36 month grind before it reaches sustainable profitability. You’re building a patient base from zero, establishing insurance relationships, managing a team that’s learning together, and covering overhead before the schedule is full.

An acquired practice reverses most of that. You walk in on day one with an active patient base, hygiene recall schedule, trained staff who know the systems, and collections that immediately begin covering overhead. For a dentist who’s been an associate for 5–7 years and is ready to own, skipping the startup phase and buying a $700K practice is often the faster path to financial independence.

There’s also a risk asymmetry worth noting. A startup that underperforms has no floor — you can lose the entire investment plus years of your time. An acquired practice generating $1M in collections has a base value even if it underperforms your projections. You can sell it, bring on an associate, or adjust the mix. The floor is higher.

That said, acquisition has its own risks. Mostly around patient retention and transition.

Key requirements and eligibility

Dental practice acquisition lenders — particularly SBA dental lenders — evaluate several factors beyond basic creditworthiness.

Clinical experience. Most specialized lenders want to see 2+ years of documented clinical experience post-licensure. They want confidence you can actually run the practice at or above the seller’s production levels.

Personal credit. 680+ is generally the floor; 720+ gets you to the best terms. Outstanding collections or recent late payments are significant red flags.

Student loan status. Dental school debt is common and expected — lenders building the SBA model account for it. What kills deals is delinquent student loans, not large balances in good standing.

Liquid assets. Most lenders want to see the 10% down payment plus some additional reserves. A practice acquisition requiring $60,000 down should be accompanied by enough liquidity to cover that plus 3 months of personal living expenses.

Geographic market. Lenders look at the practice location — local demographics, competition density, payer mix sustainability. A practice in a growing suburb with favorable demographics gets underwritten more favorably than an identical practice in a market with five competing offices within two miles.

Rates, terms, and costs

The dominant financing vehicle for dental practice acquisitions is the SBA 7(a) loan. Current rates in 2024–2025 run approximately 7–10.25% depending on loan size and the prime rate at closing. Terms are typically 10 years for a pure acquisition, which keeps monthly debt service manageable relative to practice cash flow.

Down payment requirements through SBA dental programs are typically 10% of the purchase price. Conventional practice acquisition loans (non-SBA) from bank practice finance divisions may require 15–25% down, though they can offer faster closing timelines.

Seller financing — where the seller carries 10–20% of the purchase price as a note — is common in dental acquisitions. It serves two functions: it reduces the amount you need to borrow from a third-party lender, and it gives the seller skin in the game during the transition period. A seller who wants to be paid in full has every incentive to help patient retention succeed.

Costs beyond the purchase price include legal fees ($5K–$15K for a straightforward transaction), broker fees (typically paid by the seller, but worth confirming), lender fees, and any equipment upgrades or leasehold improvements you plan immediately post-close. Budget these in before you settle on a purchase price ceiling.

Common challenges

The due diligence phase deserves its own section because this is where most costly mistakes happen.

Ask for three years of production reports, not just collections. Production shows what was scheduled and delivered; collections shows what was actually paid. The gap between them — the write-off rate — tells you a great deal about billing efficiency and payer mix quality.

Patient retention rate should be 85%+ on an annual basis. If you can’t get this number directly, estimate it from active patient counts and new patient monthly averages in the production reports. A practice with high production but declining active patient counts is losing patients faster than it’s gaining them — that’s a trend that will continue after close unless you understand and address it.

Check the payer mix carefully. A practice generating $1M in collections with 70% fee-for-service is a fundamentally different asset than one generating $1M with 70% in-network insurance. Fee-for-service practices command premium valuations because the revenue is stickier. Insurance-heavy practices are more susceptible to payer rate cuts and patient churn when coverage changes.

Associate departures are a yellow flag. If the practice lost an associate in the last two years, find out why. If it’s retirement or relocation, fine. If it’s related to the working environment or owner behavior, that will affect your ability to hire going forward.

Equipment age and condition matters more in acquisition than in an established practice you’ve been running. Get an independent assessment of major equipment before close. A CBCT that needs $40K in repairs a year after acquisition is a cost you didn’t model.

The transition plan itself requires negotiation. Standard terms include the seller staying on 3–6 months post-close — ideally with scheduled patient introduction appointments during the first 60 days. Avoid practices where the seller’s personal charisma is literally the product. I’ve worked with clients in Columbus who acquired practices with technically strong financials but deeply loyal patient bases built entirely around a retiring dentist’s 30-year relationships — the patient retention was 72% in year one instead of the projected 90%. That’s a meaningful revenue miss.

How to qualify

Start the financing conversation before you identify a specific practice. Pre-qualification from a specialized dental lender tells you your likely loan ceiling, rate range, and any credit issues you need to resolve before submitting a real application. It also makes you a more credible buyer when you make an offer — sellers and brokers treat pre-qualified buyers differently.

Assemble your documentation early: two years of personal and (if applicable) business tax returns, personal financial statement, current pay stubs if you’re still employed as an associate, dental school diploma and license verification, and a written description of your clinical experience and specialty.

Once you have a signed letter of intent on a specific practice, your lender will also need the seller’s three years of financials — typically coordinated through the broker. The lender will order their own practice appraisal as part of underwriting.

Buying a dental practice vs alternatives

The main alternative to acquisition is a de novo (startup) build. Startups typically cost $300K–$600K for a fully equipped first operatory, $500K–$1M+ for a multi-operatory build. The SBA financing structures are similar — 7(a) for equipment and working capital, 504 if you’re buying real estate. But the revenue ramp is slow and the risk of underperformance in year one is higher without an existing patient base.

The other alternative is joining a DSO (Dental Service Organization) as an associate or equity partner. DSOs often pay premium acquisition multiples — sometimes 5–8x EBITDA — when they’re buying into a high-performing market. The tradeoff is autonomy: clinical protocols, staffing, vendor relationships, and scheduling systems are centralized. For a dentist whose goal is to build and own an independent practice, the DSO route isn’t really an alternative — it’s a different career path.

Buying a second location is a variation on acquisition that many successful practice owners pursue after 5–7 years. The underwriting is somewhat different — lenders want to see the first location operating well and the owner-doctor able to manage two sites. Our dental practice financing hub covers multi-location expansion financing as part of the broader strategic picture.

Getting dental acquisition financing through eBoost Partners

We specialize in dental practice acquisition financing and work with both first-time buyers and experienced practice owners adding a second location. Our relationships with specialized dental lenders — including Live Oak Bank, Bank of America Practice Solutions, and TD Healthcare Finance — mean we can move fast and advocate for your file with underwriters who know how to read dental financials.

Here’s a deal that’s representative of what we do. A Columbus, Ohio dentist with seven years of associate experience came to us to buy a 2,400-patient general practice listed at $680K. We structured a $612K SBA 7(a) through Live Oak Bank — 10-year term, 7.5% rate, $68K down. The seller stayed on for a structured four-month transition. Patient retention in year one was 91%. That practice is now generating more revenue than it did under the seller, and the dentist is two years away from fully owning it free and clear.

We also help clients think through the broader business financing picture — working capital, credit building, and what the balance sheet should look like three years post-acquisition. And if you’re early in your thinking about business credit more broadly, our business credit guide is a useful starting point.
