Your post, @Steven Westlake, reminds me of others here asking about car washes and self-storage facilities. 

He has other medical issues and we’ve had to call 911 on him for falling at least 7 times. 

We've done buy and builds ourselves or can do BTS's but retail medicine in general has a hard time making the debt on a ground lease work, so if you are looking to do that the medical space is likely not the user for you, but if you were looking to BTS or to sell, its a solid end user to work with.

He went to BYU with the intention of becoming a doctor, but did poorly in chemistry which would be required as a prerequisite for medical school.

(So you don't help to build up the rest of our medical bills through the medical system of course.)

And, even if you could find an appraiser to do an evaluation, it's not clear how that would help you.As you state, the motel has been shut down for nearly three years, so there's no current financial data.But even if you had recent numbers, you're planning to operate it as a sober living facility, which I suspect is a very different business model.You need to find a comparable facility in or near your local market and develop your own customized financial analysis model based upon this particular property.Then, given your business objectives (cash flow and cash-on-cash return, I assume), you'll need to back into what purchase terms you'll need to achieve those objectives.Only then will you be able to determine whether these seller financing terms will work.As far as documentation to get started, a letter of intent (LOI) is commonly used but you might move straight to a purchase and sale agreement, particularly if no agent is involved.Whichever path you choose, just be certain to give yourself plenty of time to thoroughly perform your due-diligence.

My research revealed that there was no broker specializing in automotive repair facilities in the Houston metropolitan area, so I decided to become known as the “go to” source for automotive facilities.

I will be renting out the home to an individual who will be sub-letting the home to an Assisted Living Facility.

If you got of law school, medical school, dental school, or grad school, you could still qualify. 

I'm a wholesaler/investor in GA and the areas I come across deals are in Albany, Macon (college area, Amazon Facility), and Warner Robins (college area, Air Force Base).
