A modest increase in interest rates and home prices kept housing affordability at a 10-year low in the third quarter of 2018, according to the NAHB/Wells Fargo Housing Opportunity Index (HOI) released last month.

In all, 56.4% of new and existing homes sold between the beginning of July and end of September were affordable to families earning the U.S. median income of $71,900. This is down from the 57.1% of homes sold in the second quarter that were affordable to median-income earners and the lowest reading since mid-2008.

The national median home price edged up from $265,000 in the second quarter of 2018 to $268,000 in the third quarter. This is the highest quarterly median price in the history of the HOI series. At the same time, average mortgage rates rose by a nominal 5 basis points in the third quarter to 4.72 percent from 4.67 percent in the second quarter.

“Continuing home price appreciation and rising interest rates coupled with persistent labor shortages are contributing to housing affordability concerns,” said NAHB Chairman Randy Noel. “Builders are increasingly focusing on managing home construction costs so that they do not outpace wage gains.”

“Ongoing job and economic growth provide a solid backdrop for housing demand amid recent declines in affordability,” said NAHB Chief Economist Robert Dietz. “However, housing affordability will need to stabilize to keep forward momentum from diminishing as we move into the new year.”

Greater Greenville

The index for Greater Greenville rose to 71.7 in the third quarter from 69.3 in the second quarter, but fell from 74.7 in the same quarter last year.  House prices fell slightly while income remained the same.  Greater Greenville ranks as the 96th most affordable housing market in the country.

There, 88.2% of all new and existing homes sold in the third quarter were affordable to families earning the area’s median income of $74,100. Meanwhile, Kokomo, Ind. was rated the nation’s most affordable smaller market, with 93.2% of homes sold in the third quarter being affordable to families earning the median income of $64,100.
