L.T.
Try Carriage Crossing. We're on 130th Terrace and love it! The houses were built in the late 80s-early 90s so the area is well established with no construction. There are a few houses for sale in the 290-330k range. We're in Blue Valley school district and it's in the top three in the state (if not the top). We're close to everything, too. I can refer a couple of realtors if you need one of those as well.
We just moved here in November from VA and absolutely love the area!!!
Good Luck!
