Octobers S&P/Case-Shiller Home Price Index shows that home prices are continuing to ascend to all-time highs with no signs of slowing down.

October 2017’s national index comes in at 195.05, a 6.1 percent year-over-year increase from August 2016 and a seasonally adjusted 0.1 percent month-over-month increase.

“Home price increases appear to be unstoppable,” said S&P Dow Jones Indices Managing Director and Chairman of the Index Committee David M. Blitzer in a statement. “The ongoing rise in home prices poses questions of why prices are climbing and whether they will continue to outpace most of the economy.”

Coupled with a strong economy, mortgage rates that remain historically low are creating market conditions that support home prices reaching all-time highs. But as the Fed bumps up short-term interest rates, demand is expected to weaken and eventually soften the cost of housing.

Seattle reported a 13.2 percent year-over-year price increase, followed by Las Vegas with an 8.6 percent increase.

San Diego shored up the end of the pack with a 7.8 percent increase.

The 10-City and 20-City composites reported 0.5 percent and 0.4 percent seasonally adjusted month-over-month increases, and only San Francisco reported a negative (-0.1 percent) monthly price change.
