@Noureen A S. we moved to Wendell in 2012. Wendell Falls is right in our backyard (we aren't in it though, when we got here it was still defunct and had the roads paved but nothing going on). Wendell has exploded in the past 2 years or so since that neighborhood went in. Our home value has increased by about 50% per Zillow and Redfin estimates.
As far as unemployment...I think you can basically consider it Raleigh, so it's low. Downtown is about 20-25 minutes from here. Most people work in Raleigh, and on out towards RTP.
Wendell and Knightdale are pretty closely linked...Knightdale being more of a bedroom community I think. Wendell proper is a bit further out but has a much more lively downtown area. For me, both ticked all of the boxes for investing but price. Just a little too hot for me right now.
