Despite the uneventful start to the week yesterday, Mortgages Rates are sharply higher today, rapidly re-introducing 4.0% as the more prevalent Best-Execution rate. Yesterday, 3.875% was the clear choice for Best-Ex. Movement between the two has been seen more frequently as rates in general have spent more time hovering in a narrow range between 3.875 and 4.0% on average so far in 2012.
