I just saw this question and wanted to respond as I have been helping my mom through the process of narrowing down and deciding on an over-55 community in the Raleigh/Durham area (she currently lives in California) and Carolina Arbors by Del Webb is one of her finalists.
I encouraged her to look at Del Webb (which she is very familiar with as she has friends who live in the Sun City community in the Palm Springs area) and, specifically, at the new community in Durham because it is more affordable than the current Del Webb community in Cary (Amberly) but has all of the same amenities and similar floorplans. I have sold quite a few homes in Amberly, as a broker, but I think that the new Del Webb community in Durham is in a better location as it is so close to all of the shops and restaurants in Brier Creek, as well as in close proximity to downtown Durham with all of its cultural activities (i.e., Durham Performing Arts Center, the Carolina Ballet, continuing education classes at Duke University, etc.), a 15 or 20 minute drive to Lake Jordan in Durham or Falls Lake in Raleigh, and convenient to the airport for travel.
We also like the fact that Del Webb builds a very good quality home with lots of included amenities and features. The floorplans seem to work quite well too.
Please let me know if I can answer any other questions for you!
Good luck with your decision. If I can help in any way, even to answer questions, contact me.
Whatever you do I would definitely recommend getting a buyers agent to act on your behalf, especially if you are relocating from out of the area. You need someone on the ground to check on things as the home is built. Also if any problems or miscommunications arise it is preferable for you to have a professional real estate broker representing just your interests. After all the builder/developer will have a team of agents representing their interests. Best of all it usually will not cost you anything as the builder and developer will pay your buyers agent their commission.
If I can be of any further assistance please do not hesitate to contact me.
PS: There are also some other 55+ neighborhoods near Chapel Hill and down in Apex. Let me know if you would like information on them.
