Vacation Home near Miami, FL

[J Ken]

I am looking into purchasing a vacation home (3- or 4-bdrm single or multifamily) around Miami FL. Considering using it as a short- or medium term rental property and once in awhile throughout the year occupying it myself.  Also, planning to turn it into my retirement spot when I reach that stage in my life. 

Thought's on the best  towns/cities/suburbs/neighborhoods around Miami FL (can be within 30 - 45 minute drive) that:

- Is Not in flood zone

- Can be on its way to gentrification (1-7 years in future)

- Has diversity (I grew up in urban/suburban areas of NJ/NYC so like to be around folks from all walks of life)

- Near entertainment / night life
