I agree with the other agent, no one can know for sure. Ever hear the saying you cant catch a falling knife? In reference to buying stocks and wanting to buy a stock at its absolute low. We are at historic lows now and the Fed has been buying down the rate, I thought they would be going back up by now. Personally, I don't think they can get much lower but I sincerely do not know either. As a Realtor, I talk with a lot of mortgage brokers. The rule of thumb for a refi is if you can save 1 pt interest rate and you will be living in the house at least another 2 yrs, it is worth it. Hope that helps. Personally, if i had clients that found a house they loved, I would not recommend waiting for a lower rate before putting in the offer cause you just dont know right now.
