Great questions - I began on a similar journey, and
documented a bit here, and in
my blog post. (There you can find a link to the original PDF/map of the Withers Preserve master plan).
Having moved from Boston to Myrtle Beach, I now rent in DR Horton's Highlands community and I've since purchased
witherspreserve.com - former site for Withers Preserve, which was the name given to a much larger area after the air force base property was handed over. I intend to do a more thorough writeup of the history, current offerings, and links to various opinions, as well as sharing my own. I'll see about working on that further over the holidays.
The short answer is that thus far, all the developers I've seen leave something to be desired.
My quick observations are that:
Lennar & Beazer skimp on structural strength
DR Horton has poor finishing at the moment, due to poor oversight of sub-contractors
Dock Street Realty is building extremely dense homes, and I've yet to meet an owner or tenant who has said good things, but I don't have any details.
I'm waiting to see
Cresswind come in the spring, and I'm eager to see if the banks are successful in selling any of the remaining property to prospective developers in the near future.
As far as businesses: Too many tried to start during the downturn, when there were high hopes for the prospects of a budding community. When the housing downturn struck, developers went out of business, and businesses in market common were left with high rents, and fewer customers, and customers with less money, and fewer tourists. Some went out of business. Doesn't mean the area is doomed: This happened all over the country.
To put things in perspective, Lennar sells on average 10-15 homes a month in Emmens Preserve. Customers are primarily retirees from the north buying single-story homes.
