According to 'The Wall Street Journal', 43% of those buying houses the past few years have put down 2% or less!
With interest rates heading up, and housing prices going the opposite way, there is a real chance that many newer owners will owe more on their houses than they are worth.
And you know there is a peoblem when even that rag starts voicing concerns......................
I think there is an even better chance that was the situation when they signed the papers to buy the house. Some markets have been over-priced and in those red hot markets people agreed to pay more then it's worth (it was worth it to them at the time).
