Just saying, you may have an opinion, but you're likely mistaken as they do go through a medical reviews.Now, if you see a guy who says he has a bad back and you see him at the gym bench pressing 200 lbs, photograph it, document it and report it.....or just report it.

People always need housing and speaking of MTR there will always be insurance claims and traveling medical professionals.  

A ton of STR's opportunities include traveling nurses for hospitals, medical centers, and campus sights for OSU students.

These typically are the largest users of travel medical professionals.

San Francisco has a number of hospitals for travel nurses and other medical workers and probably corporate professionals who travel there.

Due to medical reasons a couple came to me looking to sell their house at a discount.

Everyone in the house is a doctor, medical student, resident. 

I work for The Realty Medics, a property management company here in Orlando. 

I will still make no exceptions for evictions on a record, no matter how other criteria works out, but a divorce, medical bills, student loans, etc., are worth questioning before rejecting.
