California home sales fell year over year in August for the third time in four months as affordability constraints sidelined some would-be buyers. The Golden State’s median sale price rose nearly 7 percent year over year but held steady month to month, below June’s $500,000 all-time high.
An estimated 43,393 new and existing houses and condos sold statewide in August 2018 (Figure 1), up 4.7 percent from July 2018 and down 7.1 percent from August 2017, CoreLogic public records data show. The average change in sales between July and August since 2000 is a gain of 3.7 percent. Between this May and August, only July posted an annual sales gain (up 1.2 percent).
For summer overall – June through August – California home sales fell 5.5 percent year over year. When viewed by the state’s major regions, summer sales tended to decrease the most in higher-cost coastal areas, except on the Central Coast, which posted a relatively small annual decline of 1.9 percent (Figure 2). Among the state’s major regions, Southern California logged the largest year-over-year decline in summer 2018 sales, down 6.8 percent, followed by a 6.6 percent decrease in the San Francisco Bay, a 4.7 percent drop in the Sacramento region, and a 2.6 percent decline in the Central Valley.
The median price paid for all new and existing houses and condos sold statewide in August 2018 was $495,000 (Figure 3), unchanged from July and up 6.5 percent from August 2017. The annual growth in the median sale price has held steady the past few months at about 6.5 percent, while the highest annual gain so far in 2018 was 9.5 percent in February. In nominal terms the median hit an all-time high of $500,000 this June. Adjusted for inflation, however, the median has not returned to its pre-housing-bust peak in March 2007, and this August’s median was 14.5 percent below that peak.
The decline in affordability that hampered sales this summer reflects the increase in both home prices and mortgage interest rates. While the state’s median sale price rose 6.5 percent year over year in August, the monthly principal-and-interest mortgage payment on that median-priced home jumped 15.3 percent because of a roughly 0.7 percentage-point gain in mortgage rates over that period.
