Del Webb/Cane Bay is one of several master planned communities, currently under construction in the Summerville area. As noted there are several new community pockets in Cane Bay, as well as a YMCA.
Closer to Summerville is the Carnes Crossings development, again a master planned community, which is now building homes.
Several other large master planned communities are under construction, as well as new construction infill communities.
Finally, other communities are in the planning stages in the area in early stages of development.
As stated below, resales in areas of new construction can often be a difficult situation, producing some good opportunities, if you are not interested in new construction.
As a licensed Civil Engineer I tend to be engaged early in planned community developments. If I can be of further assistance, to include a potential tour of the areas new developments, or available homes, please let me know.
