If you buy a house, and you get a 4 percent mortgage, you'd think it's a pretty good deal if you were a Republican. The problem is if you buy a house at $200 and a 4 percent mortgage, and the house is only worth $100, you're essentially paying a 46 percent mortgage. The actual math is more complicated but one gets the point I should hope. Seriously dude, only Republicans think that lowering mortgage rate to 4 percent would actually help anybody.
