Short Term rental and Use as second home in Florida

[Suhaib Rehman]

Good day everyone, 

I am interested in purchasing either a condo or a townhouse for short-term rental. I am also open to a longer rental as long as I could use this place for 1-2 months as a second home (summer or winter break). Budget at or under 400K. HOA and insurance costs as low as possible.
Can you suggest a few good cities in the FL with lower vacancy rates and close to nature/activities?

I am open to both the Gulf side or Atlantic/east side of south Florida.

I plan to travel to FL early next month and want to have some idea of good cities/regions to start with. Your advice will be beneficial.

Regards

Suhaib
