In fact, we just put a parcel of land into escrow in Fullerton, hoping to do a medical office building on it if all goes well.

They want to sell me the property asap due to the fathers medical bills that are unpaid. 

However, i have a small medical office building (around 1242 sqft).

When people can’t pay bills and are forced into bankruptcy by medical costs, are the doctor’s fees scrutinized?

If, but "commercial" you mean things like office, retail, medical, industrial, etc. space.  

I am 59 years old and I found BP about a year ago and I have not decided which niche to get into when I get over my medical condition.  

Type (medical or other?)

4) What should I be doing to make this happen with regard to our finances, our credit (my score is only 640, less than 6k in debt, all medical, all fairly old but still within SOL and the wife's is about the same, little higher score).

Now that I do the problem I'm having is a lot of traditional lenders won't lend under $50,000. second issue being that my credit isn't great not because of repos or foreclosures but more because of medical bills and old student loans.

Also there are many pros about this deal, there is a new hospital accross the street and another one that has a medical school program 1/4 miles down the street.
