Cig 1988, Lake Lanier is a great place to live and boat.
The trip into Norcross would take 35 minutes or so with no traffic from the West side of the lake (Cumming). It can also take up to nearly an hour in rush hour traffic.
I would plan on 400k plus for a decent home on the lake. You can find some in the 300s but they are more like cabins or weekend homes. Like everyone has said,
some deals are out there.
