Mortgage to House Value Ratio

Do states keep a record or benchmark for house to home value ratios to monitor already defaults or prospective defaulters etc. Is there a place I can get this information for both National and state levels. Much appreciated.

Yes. You can find this by searching on google.

This is commonly called LTV (Loan to value) to aid in your Googling.

I did jcole. Cant seem to get exact negative equity vs house prices statistics though. I would like it going back to early 1990 up to now. Possible percentage of them in defaulters, the folks who walked away from mortgages.

thanks serviced. Mate are there any structured debt products to address these currently in the market?
