Be careful about where you choose to be. Most if not all of FLA is hot and very humid in Summer. We rented inland then quickly decided it HAD to be coastal FLA for the nice Breezes. The Villages is VERY hot and humid. We lived in SoCAL for almost 20 years before moving to NE FLA and it took a lot of time to a) Get used to the much slower pace of life, b) We were in "Perfect" weather withdrawal for a long time too.
We chose coastal small town FLA for a few more reasons other than those mentioned above:
1) Everyone is really friendly and crime is really low
2) Everybody always seems happy here and generally in no real rush, they are either on vacation (happy), retired (happy) or getting married (happy at least for the time they are here)
3) Traffic is manageable most days
4) Cost of Living is lower that SoCAL. (electric bills are half)
5) RE in our area is a little more than normal but in general it is very manageable
6) No income tax, low Sales Tax (6%), RE taxes are about 1.7% homestead takes $50k off Taxable Value (As opposed to say Houston's ~3%)
The downside is the heat and humidity, no seeums at dusk, old folk driving in the wrong direction and backwards all over the place
.
The first 2 can be fixed by living within a couple of miles from the ocean and a screened in porch. The last unfortunately is an occupational hazard.
Enjoy.
