If you are just looking for schools in the Chapel Hill/Carrboro school district here's how. Set up 3 searches with each of the 3 high schools. Chapel Hill, East Chapel Hill and Carrboro. That will give you all of the schools in the district as the elementary, and middle schools will feed into on of the three schools. Set the price, bedrooms and other parameters as you usually would.
If you are interested in a neighborhood put your choice in the subdivision drop down.
Thanks and happy looking!
