Anyone have the relative disparity between home price in an area and income of the home borrower?

I’ve often thought that data would be the most beneficial in determining the relative strength of an area.

I think that data is virtually impossible to gather with the slightest bit of accuracy due to the huge percentage of “stated” loans done over the last 3 years.

That actually might be telling in itself, percentage of stated loans done per zip code. That could probably give you an idea. Wonder if the lenders would volunteer to give that up?
