I don't know too much about Winder, GA. Here is a little I know. I only drive that area one time.
It is in barrow county. Kind of still small town there. But maybe soon take over by Atlanta spawling when and if Dacula, GA (Gwinnett county) becomes expensive enough. School system, depend on what your standard, is ok. House is still very affordable there. But it is growing pretty fast as well. You can check school stat.

You can check Gwinnett daily post for some articles on Barrow County as well.
There is 55+ community as well. Three boys accidentally set fire on a couple of houses in adult 55+ community. But eventually, elders and kids' parents settle the case. That was big news a couple of weeks ago.
