It seems a bit out of the mainstream which probably has its pros and cons.

My vacation home I bought last year, I don't really like the loan bc its 4.375% and basically the tenant is the son of a family friend in medical school so he will be there for a few more years which is great for me.

I have medical degree and post grad degree public health !!

I think most of these large shell spaces like the 100,000+ SF buildings will be converted into call centers, climate controlled storage and possibly medical centers or schools.

Most mainstream property management software has built in ACH (or CC payment even).  

Desire.Totally agree but always like to make the following point:I know this is contrary to popular belief, but the ROI for surgeons and medical professionals (17% ROI) is actually significantly lower than for MBAs (27% ROI).This is because of foregone wages, foregone 401K contributions/matching, foregone investing and because of very large student loan balances. 

The mainstream media is focused so much on what is going on in CA or New York but there is a lot happening in the country that never makes news ....until it's too late. 

The bad credit scares me but this may be to medical bills.  

And let's not forget medical bills that go straight to collections without even giving a person a chance to pay it first. 

It's a really niche market, but the good news is that if you can't rent to students, you still have the  mainstream market to work with.
