"The wild card is interest rates. They are not doing much damage right now, but another .50- .75 basis points higher and the marginal buyers will be pushed out and the everyone else is going to drop down a rung on the price scale. If this happens, it will be another cap on prices."
As marginal buyers are pushed out they become excellent renters. The ideal renter is someone who could buy but doesn't want to for some reason. As more people own, the pool of good renters gets smaller. As cost of ownership goes up, the pool of good renters goes up. I'm in Chicago suburbs also, and see roughly the same thing you do. Maybe a 5-10% pullback in the middle tier (300-600k)and a little more time on the market.
