The key to house prices is the share of foreclosure or short sales in the total housing market. When that share rises, house prices will fall, because distressed properties sell for significantly less - currently around 25 percent below non-distressed houses.

There is plenty of blame to go around for the U.S. housing bubble, but not much of it belongs to Fannie Mae and Freddie Mac. The two giant housing-finance institutions made many mistakes over the decades, some of them real whoppers, but causing house prices to soar and then crater during the past decade weren't among them.

There is no better way to quickly buoy hard-pressed homeowners than helping them take advantage of the currently record low fixed mortgage rates and significantly reduce their monthly mortgage payments.
