Surprise - interest rates just hit new lows for 2017:
Bottom Line: It seems counter-intuitive that the fed recently raised rates and we'd now find ourselves with the lowest mortgage rates in 2017 but that's exactly what's happening right now. As I indicated with the fed raised rates last month, for the third time in the interest rate increase cycle, the impact is felt by lenders borrowing from the Federal Reserve, but it doesn't necessarily have an immediate or direct impact to various loans - including mortgages. Market conditions and competition also factor into the final outcome on borrowing costs.
As of this entry the average 30 year fixed rate mortgage with good credit is at a 2017 low of 4.08%. 15 year fixed rate mortgages are also available at sub-3.5% levels once again. So if you'd been looking for a window of opportunity to refi or to rate lock a future purchase - today it literally the best day of 2017 to do so.
