Although I agree that there will be a slowdown in real estate prices, where do you get your info about Naperville. As far as I can see, and I live in Aurora one suburb over, $250,000 in Naperville won't buy much.
I get emails from a real estate agency in Naperville and surrounding areas. My Daughter and her husband may move there because of his business. The homes are huge and beautiful and the R.E. agent said there was a major slowdown and they will be able to pick up quite a nice home for $250K or less that they should make an offer and more than likely they will get it for less. MAJOR slowdown already in the burbs.
