With a backup plan, and proper (extensive) legal docs, much of the risk can be mitigated.

You have to properly vet and perform thorough due diligence (which I didn't do a couple years ago when I first jumped in).

I own 12-doors in Detroit proper.

Do you have the professionals you need to start an LLC, do the proper real estate/tax accounting, solid contractors to rehab or prepare the property, and a property manager to handle the day-to-day operations? 

This was also confirmed when I went there to submit the required documents, but they couldn't give me a proper timeline on when it would happen claiming that they were backed up. 

STR's, if done right, are viable long term investments meant to cash flow at a reasonable enough level to properly maintain and improve them. 

You can try your luck to see how long it’ll take for the roots to re-grow, but be prepared to eventually make the proper repairs.

Now if it was definitely a single unit and only she could do it and it was properly labled it would be on her.

If I have been given proper notice of move out, then generally I prorate the days past the move out date based on the actual monthly rent that month. 

@Sanjeev Advani I’m not saying they’re all like this but since Circle K bought 3 local convenience stores they have never been able to staff them properly or maintain employees.
