Again, we cannot tell you "bad" neighborhoods, but I can certainly tell you where peoople who visit or move like to rent, and that is near the water or beaches. In general, the Gables, Grove and inland areas are more family oriented, and where peole gravitate to buy homes and raise families.
If you are looking to buy a "little place" such as a small condo, the beach areas are where the rental market is very active and the rental rates are highest per square foot.
If I can assist you with your purchase feel free to contact me direclty, and for a great source go to my companies web-site below, it is linked directly to the multiple lisitng service so that you can check the prices of condos in various locations.
