Mortgage rates were little changed leading up to Wednesday's Federal Reserve announcement, with the benchmark 30-year fixed mortgage rate inching lower to 4.18%, according to Bankrate.com's weekly national survey. The 30-year fixed mortgage has an average of 0.22 discount and origination points.

The larger jumbo 30-year fixed was unchanged at 4.14% and the average 15-year fixed mortgage rate slipped to 3.39%. Adjustable mortgage rates were slightly lower, with the 5-year ARM dipping to 3.46% and the 7-year ARM retreating to 3.62%.

While mortgage rates were little changed in the days leading up to the Fed meeting, they are actually one quarter%age point lower now than when the Fed hiked interest rates at their last meeting in March. Weakness in first quarter economic growth and geopolitical concerns surrounding North Korea, Syria, and an election in France all contributed to bringing mortgage rates lower. But with the Fed's glass-half-full economic outlook, dismissing the economic sluggishness at the beginning of the year as temporary, it is evident that the Fed remains inclined to continue raising interest rates. Mortgage rates are likely to trend higher through the balance of 2017 as interest rates rise, but as we've seen recently, there are likely to be plenty of ups and downs as economic sentiment swings back and forth.

At the current average 30-year fixed mortgage rate of 4.18%, the monthly payment for a $200,000 loan is $975.70.
