Buying a Dental Practice – What are Contingencies?

Mid-America’s most trusted dental practice valuation and sales

If you’re considering buying a dental practice in the St. Louis region, you’ve probably heard the term “contingencies.” But what does that really mean for you as a buyer?

When purchasing a dental practice, the sale contract—often called an Asset Purchase Agreement (APA)—will spell out conditions that must be met before the deal can officially close. These are known as contingencies, and they protect both the buyer and the bank financing the transaction.

Typical Contingencies in a Dental Practice Sale

1. Due Diligence
You’ll usually have a set period of time to conduct additional due diligence—reviewing charts, financial records, and other details. Once that period ends, you won’t be able to request more information unless the seller agrees.

2. Financing Approval
The purchase is also contingent on securing suitable financing. Banks often take weeks to finalize approval, so it helps to start the pre-approval process early. Keep in mind, lenders will need documents like your tax returns, net worth statement, and personal budget—delays in providing them can put your closing date at risk.

3. Lease Agreement
Perhaps the most challenging contingency involves securing an acceptable lease. Lenders typically require a lease that matches the repayment schedule of your loan (e.g., a 7-year amortization means a 7-year lease, or at least a 5-year lease with renewal options).

  • If the seller’s lease is near expiration: The landlord will often be open to negotiating a new lease with you.

  • If the seller’s lease is long-term: The landlord may push for you to assume it, which may not work for your bank or the seller, since they could remain liable if you default.

Leases can take weeks—or even months—to finalize, which can delay closing.

Why Contingencies Matter

Until financing, lease, and due diligence contingencies are resolved, the seller doesn’t have certainty the practice is sold. This often prevents:

  • Early introductions to staff

  • PPO credentialing before closing

  • A smooth transition in collections and reimbursements

Even with a signed APA and a set closing date, the deal isn’t final until those contingencies are satisfied.

The Bottom Line

Contingencies protect you as the buyer—but they also add complexity and uncertainty to the timeline. Understanding them upfront will help you avoid delays and frustration.

Kim with Otten-Rey Dental Sales truly made what I thought would be a stressful process extremely easy and painless. From our first meeting all the way until closing, Kim was always reliably there for me through out the process. I trusted her system and it was simple and seamless. I would definitely choose Kim again for my transition if l had to do it all over again.

When I decided to buy a dental practice, I quickly learned that practice brokers represent the seller. As a buyer, that posed some challenges. Of all the brokers I worked with in St. Louis, Kim was the only one who managed to make me feel that she was actively trying to find a practice for me to buy. Not only did she help me find a practice I loved, but she still represented her seller well and was fair throughout the entire process. Because of her, I am now the owner of a great dental practice that I love and I truly believe she made that happen for me. Thanks Kim.

Thank you both, Kim & Bill. This has been a great adventure. All is going great with the merger of Dr. Berger’s practice. Overall, I would say it is a great success. And I couldn’t have done it without both of you.

I felt my practice purchase went smoothly and efficiently with the help of Otten-Rey Dental Sales. As a buyer, I felt comfortable with the fair appraisal that Otten-Rey put on the practice and both Kim and Bill were very accommodating getting any requested info to help me do my due diligence…Otten-Rey is known in the St. Louis Dental community for being easy to work with and I strongly recommend either buyers or sellers use them in the process of your dental transition. Having their expertise, experience and organization really made things a lot less stressful.

Kim’s understanding of all aspects of a transition was invaluable. She has comprehensive knowledge of both the financial and clinical aspects of a dental office. She also provided the guidance and understanding of the legal aspects necessary to close the transaction. Thanks Kim!

Kim Rey was my broker in representing me when I sold my pediatric dentistry practice. From my standpoint, Kim brought a great amount of stability to the whole process. I appreciate her insight and her levelheaded guidance on what my expectations should be, what the normal accepted practice and standards are when dealing with a buyer. The process was longer than I anticipated, but Kim kept me focused and on the right track until the transaction was completed. Throughout the process, she always made me feel like I could rely on her and that in turn gave me a great deal of comfort. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Several of my friends used Kim and Bill to sell their practices and had highly recommended them. I was pleased with the thorough process of valuation and the explanation of the report. They provided frequent updates and the guide for printing the necessary reports for the valuation. They found a buyer that fit our needs. I would recommend them to the other dental offices needing the same services.
