On the flip side, for many, their financial situation is not the most stable.In the latter category, you have doctors (Cleveland Clinic, University Hospitals), financiers, lawyers, educators.

The note was written at 8% interest with 240 monthly payments of $1,129.19 each.After receiving almost 7 years of payments the sellers desired to sell a portion of payments for medical expenses.

Your last sentence rings so true.When working with a professional, be it a doctor, agent, attorney, or inspector, if you are going to question and direct their work, why bother hiring them in the first place?

Real estate cash flow vs Physician/Doctor cash flow.

That's 5-10 hours a week.My regular job is about 1-2 hours a day at a medical clinic doing pre-employment drug screens. 

So, while their CCs may go months unpaid, and student loans rack up, or medical bills pile high, they usually find a way to pay their rent....and make their car payment.Tenants come with credit issues. 

The seller was only interested in a full purchase and needed to net at least $43,150 due to medical costs and challenges.That only left a fee of $250 ($43,400 less $43,150).

I don't mind medical bills and student loans much if they show up in credit or are late.

So I have an opportunity to purchase a doctors office.

You could also look into medium term rentals to traveling nurses, doctors, professors, business people etc.
