You need to talk with a Realtor. It sounds like you are thinking about selling a home in Arlington Heights. My office is right down the street from there. I know the area pretty well. Keep in mind, we have been in a very unusual market over the last five years and that data may not give you a true reflection of today's fair market value.
If you would like to give me a call, I would be happy to discuss it with you.
