Can't advise on salary, but I like Greensboro. The Triad does not get the national press that the Triangle (Raleigh, Durham, Chapel Hill) and the Charlotte areas do, but it's a nice place with some good stuff going on. There are some good schools according to test scores compared to the rest of the state. I don't know first hand. You can look up test scores at
NC Report Card.
Your price point for a house is definitely low for Wake County, but you could look around Knightdale and Garner. Don't think you'd be able to score that in Cary. Cary is super desirable with many transplants moving in every day. Apex is similar. It's worth having a look around online, but pickings will be slim for a house in that price range. Greensboro will give you more housing options.
