It really depends on what you are looking for. While the newest schools are in the Northern School district many of the other schools have had a good deal of money poured into them to renovate and/or expand them. As far as housing prices they vary by neighborhood. Also when you say North side are you referring to North, northwest, and/or northeast. They are very different. Also are you speaking of North Greensboro or North Guilford County which would include Summerfield, Oak Ridge, and Brown Summit. In North Greensboro you have Lake Jeanette neighborhoods, or New Irving Park depending on how far north you want to speak of.
If you could give just a few more details of what you are looking for such as schools, shopping, and amenities we can narrow down what you are looking for.
Hope this helps,
