Rates are up from this summer when they were at/near 5-year lows, but are slightly below rates 12 months ago and well below what they were during the huge 2013-2014 bull run (not to mention well below the rates during the big bubble).
I’ll be worried if they go above the 4.3-4.5% range of July 2013 to May 2014. Not too worried though, I am locked in for 30 years with payments well below rents.
