I-485 allows you to get to I-85 easily from anywhere to go to Greensboro. So, I wouldn't worry about that. Dh's commute would be the biggest issue, in that price range. A thirty minute commute is about minimum going into town with traffic, I'd guess. Probably more like 40 minutes, from a subdivision.
If that seems unreasonable, there are areas closer in town, but it will be much harder to know about the surrounding neighborhood safety, etc. There is a site- not sure this is it, but it has neighborhood safety data:
http://www.neighborhoodscout.com/nc/charlotte/crime/ There are others like it, if you search. You can find pockets of older (50+ year old houses) neighborhoods, closer in. But, it is a bit trickier.
Newer construction (within past 10 years), Indian Trail (SE) or University area (NE) are affordable, safer and decent commute (40 minutes into town).
We have a local holistic moms group:

You all are welcome to join and ask there also. You could post neighborhoods you find and we could say
yay or nay, perhaps? It is probably easiest, (sorta not, with kids...) to rent and search for what *feels* best to you. Charlotte is huge and each area has a personality. Some could like one area, another could hate the same area.
If you want close access to a lot of homeschoolers, the southeast is the most active. But, there are tons of events all over the city! I'd say one car would be very limiting to a homeschooler, unless near the Light rail line, on the west side of town. Which is not the safest area of the city, generally, unless you are farther out from the light rail, lol.
We love southeast Charlotte. We are in Weddington, Union Co, with much lower taxes.
