Short term rental.

I love Florida. Thinking about investing in a short term rental. 90 percent to rent and maybe 10 percent for personal use with the idea to have a place ready when I retire. However I see a lot of homes that were short term rentals and hosts are now trying to sell. Do o have somehting to be worried about. Is it a bad time to buy? Looking at areas like Deerfield or Boynton beach? Maybe Del Ray? Any advice?
