Be aware of not only flood insurance needed in most areas of Chatham County but some areas may have septic tanks that your agent should check out.
Good Luck and call if we can be of assistance.
Wilmington Park is older, but a nice safe area. Betz Creek is also a nice area, but there have been some flooding issues in the yards with homes closer to the creek at peak tides. If schools are important, Wilmington Island is very good for public schools. If you would like a list of homes for sale in that area, please let me know. I would love to help you.
