At that point like some others have alluded to I think it’s more of a commodity.

I initially paid $88k, and the last one $117k, at this price increase it will tough to get to my goal of 10 houses.As much as I don’t want to I am considering another market.My perfect property is $60-$90k, with 20% down, rent covers mortgage, tax, insurance, and 10% prop mgt, with a minimum rent of $1,000.

What price points do you stick to?

I'm feeling pretty strongly about hiring a lawyer, but I'd rather not if we don't have to.  

For example Sec 8 tenants, many people put on their listing no sec 8, but they are not supposed to.  

Sub-to is a sale, title is transferred to the buyer.

I've found that if I never see the money and in my mind never really had it to begin with, you figure out ways to spend less because you're essentially forced to.

Alternatively, another way investors use to is to keep the ownership of the building separate from the ownership in the physician group i.e. a doctor can retire from the physician group (be bought out, sell their stake, etc) yet have a separate ownership claim on the actual building. 

That's probably what I would do, not sure about your particular goals / investing style / risk tolerance, but I think having the option to pay down IF you wanted to is why the 30 yr. is better.

Here are the terms we have agreed to I am just trying to figure out how to structure this in writing if I can do this right and protect myself as well as the interests of the seller.
