First, moving to the finance forum as that is the more appropriate venue for this discussion.
Second, as someone who has helped others purchase practices in a former life, your best bet would be to approach local lenders and inquire about healthcare financing. Some banks lump doctor acquisitions in with regular loans (since usually they are only a few hundred thousand) and then have a different division for larger healthcare acquisitions and supplies. Every bank is different. The reason why I said approach local banks because those are the banks that will be more willing to bend for you than some of the large corporations. Working for a local bank we could offer multiple services to our potential customers including cash management, insurance, retail banking, etc.
Since you are a professional (whether it be physician or dentist) it is understood that your income stream will be there. Unless your credit is really bad you shouldn't have a huge issue getting a loan but you might have to disclose more financial information than you want (this was the #1 major complaint that most gave me) and you might have to use something to secure this purchase (#2 major complaint). You'd be surprised at the number of doctors out there who live WELL BEYOND their means and destroy their credit. I hope this helps a little bit but I'm sure you already knew most of it. 🙂
