That area grew fast and so did the prices ....
But if you take a real long and strong look, most of the prices have (or will) fallen somewhere in and around the 20% area ... when you see the beach area's falling like Indian Harbor in price, you can certainly bet the other area's are coming down - and have.
Be patient and try to find a good experienced and savvy agent, shop around and ask questions .... and don't be afraid to spend some time doing searches on your computer and dissecting the areas and their prices ..
As an example only, some houses there have gone from $500,000 "asking" to $420,000 "asking" ... usually your best deal is going to fall with the seller that has the most amount of equity and has been on the market the longest.
Good luck and happy hunting.!
