I'm 26 years old and am currently working in the medical field for the Navy but my future goal is to own multiple multi family apartment complexes along the East coast. 

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.

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 renters in the former work for a local wholesaler beverage distributor and the latter is a medical college student.

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. 

I also work at a medical clinic doing pre-employment drug screens for the refinery and other industry. 

There have been several here at BP who have stated that when they provide an applicant with a form to take to their medical provider to state the need for an ESA, the entire idea of this falls through the cracks like a marshmallow melting in the heat.While it is easy to purchase one of those fake "ESA certificates" online a landlord does NOT have to accept this as either adequate or accurate evidence that the animal in question is, in fact, an Emotional Support Animal.
