Next Moves For Federal Housing Stimulus

Home-buyers have been enjoying rock-bottom mortgage interest rates. But several key factors threaten to disrupt the low rates, as well as the budding housing recovery.

It has the makings of a perfect storm: The Federal Reserve may stop propping up the marketplace at the end of March. The home buyer tax credit ends April 30 (you have until June 30 to complete any April deals). And, in the coming months, Fannie Mae and Freddie Mac could top out their mortgage portfolios and not be able to buy any more.
