👍 Yep, these are all excellent points as well. Let me add to this the idea of a non-compete clause in your purchase agreement that states the retiring dentist cannot open a new practice (or take your current patients away) within a 15 mile radius of your newly purchased practice. I'm not sure about the legalities involved with this, but I've heard of many purchasers doing this. This is because a few dentists have purchased a practice from another dentist, and found out later (after the purchase) that this was a SECOND satellite practice that was owned by the dentist...whose primary practice was just 20 miles away. In that case, a boat-load of patients can continue to see the selling doctor, and you're screwed as the buyer.
The main point: make sure you exhibit your due diligence when opening/purchasing a practice...unturn every stone, protect yourself, and always be weary about a selling dentist who doesn't want to divulge ALL of the practice info to the buyer.
Remember: it is a buyer's market, so the selling dentist wants to sell his practice MUCH more than you want to buy it. This gives you (the buyer) more leverage and more power in the negotiation. So protect yourself with the proper agreements!
Hope this helps!
