The California home market is getting a bit cooler, with closed escrow sales of existing, single-family detached homes in August coming in at a seasonally adjusted annualized rate of 420,360 units, a 1.1% rise from July but a 2.2% decline from the same month last year, the California Association of Realtors reported Thursday.

Home sales remained above the 400,000 pace for the fifth straight month, but sales have declined year over year for the sixth consecutive month.

"We are seeing the market tempering, which is being driven by reduced affordability and not enough homes for sale on the market, particularly in the San Francisco Bay regions, where runaway home prices have constrained home sales," said C.A.R. President Pat "Ziggy" Zicarelli. "Two of the region's least affordable counties – Marin and Santa Clara – saw sales fall from a year ago, while Contra Costa and Sonoma counties experienced more modest slowdowns. Conversely, in many parts of the Central Valley, where homes are more affordable and demand has been relatively strong, home sales posted healthy increases. Likewise, sales of condominiums statewide were strong, thanks to their relative affordability."

The statewide median price for an exisiting, single family detached house was at its highest level in nearly seven years, up 1.7% in August to $526,580, 5.8% above the price in August, 2015.. There are, however, signs of an expected slowing in price growth.

"As jobs and incomes have continued to improve for workers in the state, we're seeing more demand by primary home buyers at the lower end of the market where inventory is tightest, which is pushing home prices higher," said C.A.R. Vice President and Chief Economist Leslie Appleton-Young. "With active listings in the lowest price tier dropping more than 27% from the previous year, the median home price of the lowest priced segment of the market was pushed up from $185,000 last year to $205,000 this August, while the next price segment of the market has risen from $300,000 to $320,000."

Other metrics from C.A.R.'s August 2016 resale housing report included:

  • C.A.R.'s Unsold Inventory Index, which indicates the number of months needed to sell the supply of homes on the market at the current sales rate deteriorated from both last month and last year, dipping to 3.4 months in August from 3.6 months in July. The index stood at 3.6 months in August 2015.
  • With the exception of Ventura, all of Southern California saw its unsold inventory decline as the market got tighter in August. Inventory either was unchanged or up over the past year in all Bay Area counties except Napa and Sonoma as new listings have started to come on the market.
  • The median number of days it took to sell a single-family home edged up slightly in August to 28.9 days, compared with 28 days in July and 29.7 days in August 2015.
  • C.A.R.'s sales-to-list price ratio* dipped in August, with sales prices slightly decreasing to 98.9 percent of listing prices statewide in August from 99.2 percent in July and essentially flat from 98.8 percent in August 2015.
  • The average price per square foot** for an existing, single-family home statewide was $246 in August 2016, down from $247 in July but up from $235 in August 2015.
  • San Francisco County had the highest price per square foot in August at $818/sq. ft., followed by San Mateo ($782/sq. ft.), and Marin ($632/sq. ft.). Counties with the lowest price per square foot in August include Del Norte ($106/sq. ft.), Siskiyou ($123/sq. ft.), and Tulare ($127/sq. ft.).
  • Mortgage rates are expected to remain low in the foreseeable future as weak global economic growth will likely be the norm in the upcoming months. Mortgage rates declined in August, with the 30-year, fixed-mortgage interest rate averaging 3.44 percent, unchanged from July and down from 3.91 percent in August 2015, according to Freddie Mac. Adjustable-rate mortgage interest rates also were unchanged in August at an average of 2.75 percent, essentially unchanged from 2.74 percent in August 2015.
