After thirteen months of shrinking gains that turned to outright declines this past spring, Seattle residential prices according to the Case Shiller Home Price Index finally improved in July. Published by S&P Dow Jones, the index of residential home sales in King, Snohomish, and Pierce Counties still shows prices lower year over year, but by a lesser percentage in July 2019 than in June. The improvement could point to a return to seasonally higher home prices across the three counties by August, as already indicated by data for that month from the Northwest Multiple Listing Service (NWMLS). Yet prices are likely to remain lower on a month-by-month basis, and prospective sellers are cautioned that the monthly increases on the index have been narrowing since March: from +1.65 percent that month to +1.06 percent in April, +0.98 percent in May, +0.56 percent in June, and +0.23 percent in July.
The shift in trajectory comes six months after a seven-month string of monthly decreases in the index that were often misreported as price declines by sources other than RSIR. During those months, there were fewer home sales in many parts of King County even as selling prices remained buoyant. But since actual price declines began to prevail in late 2018 and early this year, the numbers of sales rose in these areas, with sellers adjusting their expectations to changing market conditions. By mid-autumn, selling volumes may be expected to stabilize along with residential selling prices and market times.
In the S&P Dow Jones press release announcing the July Case Shiller results, Philip Murphy, Managing Director and Global Head of Index Governance at S&P Dow Jones Indices reported:
Charlotte surpassed Tampa to join the top three cities, and Seattle may be turning around from its recent negative streak of YOY price changes, improving from -1.3 percent in June to [-0.6] percent in July.
Overall, leadership remains in the southwest (Phoenix and Las Vegas) and southeast (Charlotte and Tampa) … Home price gains remained positive in low single digits in most cities, and other fundamentals indicate renewed housing demand.
In recent months, other cities with slower-rising prices have joined Seattle in seeing their year-over-year index gains reduced: Atlanta, from +5.8 percent in July 2018 to +4.0 percent in July 2019; Chicago, from +3.0 percent to +1.6 percent; Miami, Florida, from +5.0 percent to +2.7 percent; and New York City, from +3.4 percent to +0.9 percent.
Among other West Coast cities, Case Shiller shows residential price trends in San Francisco and Los Angeles following the path established earlier by Seattle, while prices have risen steadily in Portland and widened their gains in San Diego. August selling price statistics from the NWMLS show Seattle residential prices higher year-over-year by August.
