Dr. Phillips, Hunters Creek (some areas), Celebration, Clermont, Reunion, Champions Gate and Windemere are all nice and pretty close. Plan on $800/month+ for rent now, $250,000+ for a condo or $350,000+ for a house in the nicer areas. The bubble is starting to burst here though-tons of homes on the market. You may want to check out the threads on the Budget Board about homeowners insurance. Not a big deal if you are renting but if you are planning to buy good luck. Some people in the homeowners thread have seen their homeownes insurance go up 100% or more. My parents moved from NY last year and their property insurance just went up 40%. They are paying a lot more than they were in Queens, NY!
I would have good jobs lined up before you come!
