It was explained to me that most commercial real estate owners do something with it in the first 5-10 years so it doesn't matter.   

Undocumented immigrants often won't have any government issued IDs so it is a defacto fail.

After a month of staying in the unit, the Tenant calls me to tell me that they need to break the lease because he has to relocate unexpectedly.

Hi Christoph,Thanks for the feedback.Yes, I am not considering Germany so much.

Can you screenshot your settings now so I can see what may be the problem? 

Upon phone messaging or emailing them my first big surprise was that quite a few commercial agents wouldn’t even return the call or seemed standoffish.

Florida is a challenging state so I would highly suggest working with a broker familiar financing deals in this area.

Or as my wife likes to call it: "man-sitting"Contractors unwilling to execute on what you hired them for (I.e. current flip, cabinet installers were supposed to put up fill and crown.  

That was a prime investing market, so your experience won't be the same today, but you can definitely improve your station in life within 5-10 years.

In fact, it's still confusing to me so I mainly avoid it at all costs.
