My in laws live in Mt. Prospect. There are a nice mix of homes but they are not inexpensive. A house on her street is currently listed for over $650K and it's nothing special. Some newer tear downs are quite large and very $$$.
At the opposite end of my in laws street are low income apartments and several more around the corner. She lives close to the UAL HQ.
She has never had any crime issues and have lived there for 10 plus years. Convenient to 90 and downtown A.H. and Schaumburg so they have shopping, dining, etc.
