Good morning, Ashley:
There are 15 stations on the Lynx Blue line which runs from Uptown to Pineville. You'll probably find that the most expensive are: East/West Blvd, Bland Street, Carson, Stonewall, 3rd Street/ Convention Center, Charlotte Transportation Center / Arena and 7th Street and the others are more affordable. There are about 100 single family homes within about a mile of the Blue Line: http://goo.gl/aO4rY
If you contact through profile with the preferred station(s), preferred distance from the stations, home features and price range, I can provide a refined list. If you appreciate an answer, please give thumbs up. For the most helpful answer, please say thanks with a best answer click.
