According to ATTOM Data Solutions Q2 2018 U.S. Home Affordability Report, U.S. home prices in the first quarter were at the least affordable level since Q3 2008.
The report calculates an affordability index based on percentage of income needed to buy a median-priced home relative to historic averages, with an index above 100 indicating median home prices are more affordable than the historic average, and an index below 100 indicating median home prices are less affordable than the historic average.
Nationwide, the Q2 2018 home affordability index of 95 was down from an index of 102 in the previous quarter and an index of 103 in Q2 2017 to the lowest level since Q3 2008, when the index was 86.
"Slowing home price appreciation in the second quarter was not enough to counteract an 11 percent increase in mortgage rates compared to a year ago, resulting in the worst home affordability we've seen in nearly 10 years," said Daren Blomquist, senior vice president at ATTOM Data Solutions. "Meanwhile home price appreciation continued to outpace wage growth, speeding up the affordability treadmill for prospective homebuyers even without the rise in mortgage rates."
