deficit in number of new homes built accumulated over the last decade vs what would be needed. Even building an extra 1mm a year it would take years to smooth that supply side of the equation. I don't know that demand will sync that low. It may for 12-18 months because of the recession we are in the beginning stages of, but medium term it won't. Compared to 2006-2008 when we were at a surplus of about the same amount.
In a foreclosure, price doesn't matter. Just ability to make payments. So that cost of home ownership is a function of rate and price.
