We posted this chart in February. We have been accurate to the T this year. We also predict even higher home values next year and even lower rates. If you just refinanced or purchased, do not panic, you are not missing a window. Stay tuned for next years rates.
If you have had your loan for 4 months or more, then I would consider redoing your loan now for the lowest rate with the most credit and prepare to do it again next year. This way just in case it does not drop, you still have the best opportunity.
