How lower would you like them. Interest rates are at all time lows. Depending upon your loan limit whether it be jumbo or conventional todays rates are excellent. Combine that with a buyers market, and i cant believe more people arent taking advantage of the current market.
Rates are very sensative subject right, and knowone will be able to predict what is to happen. So your best bet is to think about how much they could actually go down, compare that to what if they go up again. They are pretty good, so take advantage.
