Rental Property Market Analysis Cental Florida

[Eric Starks]

I am currently doing my market analysis in the central florida area and narrowing it down to my top cities. I am looking for a little advice on what others have done and how far I shoud I narrow my search.  Should I stop at the county level, city level, or zip code?  Should I look at multiple markets, lets say my top 3 - 5 or should I focus on just one?  Any  help is greatly appreciated.
