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.

I have worked with Otten-Rey Sales as a “buyer” for two separate practice purchases in recent years. From the buyer’s perspective- I have found Kim very easy to communicate with and very accommodating to any requests I may have had while doing my due diligence. Kim has been a great resource and when the time comes to consider selling, I would absolutely feel comfortable asking her to represent me as a seller as well.

My transition experience was truly smooth and easy from start to finish. Kim made what could have been a stressful process feel very manageable. She was always quick to respond, proactive in communication, and genuinely cared about making sure everything went right. I felt supported and informed every step of the way, which gave me a lot of peace of mind during such a big change. It was a wonderful experience overall, and I’m very happy with how everything turned out. I would absolutely recommend Kim to any dentist going through a practice sale or transition — she really goes above and beyond.

Dr. Hetal Patel Clayton, MO Practice

We consider ourselves lucky to have known and worked with Kim Rey for so many years. She was involved in our purchase 19 years ago and has been a supportive, positive presence in our office management since that time, up until the successful sale of our practice. We feel like our timeline was truly understood when meeting with Kim about our needs and our goals for our practice and our family. She helped to guide us each step of the way with those goals in mind. We feel like the communication was clear and consistent with her management and care of our sale. We always felt like a priority to her and it truly made the sale of our practice an exciting and enjoyable process. I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.

Dr. Patrick Murphy Arnold, MO Practice

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.

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!
