In reviewing multiple sites, I have found that Jim's Mortgage Matters really does a good job of summarizing trends.
Note the quick analysis on refinances being down with the new rates(up a point-1% in past 30 days) while purchases are up 2%.
Purchase applications have seen a double digit increase over the past year(16%).
As Jim notes, no one can predict where mortgages will go!!!
Yet, Fed action seems to indicate they will continue to rise...but who knows! Home prices continue to strengthen also.
So are you willing to risk the chance of the double whammy of higher rates and higher prices??? Again, no guarantee that you will face this situation but the probability is very real.
