I just defer to my friend who's an ER trauma surgeon. 

I used legal zoom to form my LLC, it works to get started off but when you're net worth is higher, I'd recommend reconstructing your LLC through a lawyer. 

We have a very small hospital with very few beds and something like 6 surgeons total.

I am reconstructing my home(knocked down and rebuild)  which already has a fha mortgage of 375K.
