I'm wondering if once TV finishes building new homes, if some of the "tourist resort" feeling will subside some. The lifestyle visits will end as there will be no more new homes to sale. I realize everyone will not live here full-time, and some homes were purchased for investment and for rental.
The only downside we found out after several years of visiting, was the residential areas aren't truly gated. We fell in love with TV in April 2005. Our week down in 2006 was to ask, in person, just what you are asking here. We found one gentleman who said, "it's getting too big".
We soon will be "FROGS"! From TOTV and our many visits, we have seen and learned some the annoyances, which some have posted here already. Even knowing that, they are things we are prepared to deal with. No matter where you live, there are things that drive you crazy (loud music from the car next to you, inconsiderate people, people driving too fast, etc.) I don't think you will find any "surprises" that you haven't already experienced.
Make sure you understand what living in a Community Development District means and what additional expenses you'll have. If you find them acceptable, then get rid of your junk (like we are doing) and COME JOIN US in lower paradise!!
We are absolutely
GIDDY ABOUT BECOMING FROGS!
