The Iran war is a major factor pushing up mortgage rates. Some would-be buyers are backing off amid high costs and uncertainty stemming from the war. 

The median U.S. monthly mortgage payment is $2,742, up 0.4% year over year. While that’s a small increase, it’s the first in nearly six months. 

Housing payments are climbing because the Iran war and rising oil prices have pushed the weekly average mortgage rate up to a six-month high of 6.38%. Daily average mortgage rates rose as high as 6.64% at the end of last week. Home-sale prices are a factor, too; the median home-sale price rose 2.1% from a year earlier during the four weeks ending March 29–the biggest uptick in a year.
