I don't have a suggestion, but rather a warning.
Friends are FIRING in Jan 2017. They want to spent one month in a specific town in Florida to test the waters there before they buy something. They are finding that their only option is for a minimum 3 month stay, for 12k! that's 4k/month...
So be ready for some wacky, over the top rents.
I am moving in to a fifth wheel and wanted to live in the city I live in now (selling our home as I type this). However, I called all three RV parks. They only do long term rentals in the winter and are on summer rates now (short term only) AND, I would need to get on a wait list... sheesh I had NO idea.
Here's the even crazier part. My current mortgage for a 2200sf home is $862/month. If I DID find a long term spot available, it would be $600+/month for a measly gravel pad! Electric is metered.
So, I hope you are researching well ahead of time so you can budget accordingly.
The best of luck to you!
