The headline for the article says 30% of mortgages but the body of the text says 27%.
In any event the rate is going up.
Housing is the biggest issue that effected the recession and the biggest result of the reduction of Americans net worth.
And the worth is shrinking still.
Another stat in the article is that 1/3 of all homes sold in December for a loss. Not just a loss on paper but a realized loss, mostly for the banks who should have had reserves for this on their books at this point.
The economy is getting better but there will still be that nagging loss of confidence as long as such a high percent of people feel stuck in their homes.
Once the huge backlog of foreclosures gets caught up and a good number of short sales get completed, the under water rate can go down and confidence can go up.
I don't expect home values to go up to cover the gap and that would just make home ownership less affordable, anyway.
It's a long road back form the bursting of the housing bubble.
