I have to believe THE upcoming area is Lake Secession, which is about 30 minutes south of Anderson.
If you compare the prices of lakefront property on Lake Secession with similar properties on Lake Hartwell and Lake Keowee, you can get SO MUCH more for your money on Lake Secession. Also, the water level on Lake Secession is managed by the power company and it is let down in the fall and winter so owners can repair their docks and seawalls, but is at full pool during the spring and summer. This is very important when you consider the drought conditions that have impacted this area over the past few years. For example, in the summer of 2008 the water level on Lake Hartwell was significantly low and many homes were on mud and not water.
Note that a 3br 2ba single family home on Lake Secession with 2+ acre lot and 300 ft of open water lakefront (not a cove) with 10 feet of water depth of the dock sold in August of 2009 for $175,000. There is no way you would find a similar home on Lake Hartwell or Lake Keowee.
