The chart below illustrates year-over-year changes in home values using the 3-month period of December, January and February sales: 6.4% appreciation in median sales prices and 11.5% for dollar per square foot values since last year. The usual reason why median price and price per square foot appreciation rates diverge like this is because the average size of homes sold during the 2 periods changed, and this is what occurred from last year to this year: Average house size dropped a little over 9%. All thing being equal, smaller homes typically sell for lower prices, but higher per square foot values. The actual, overall home-value appreciation rate is probably somewhere between the two.

It is still very early in the year to come to definitive conclusions, but so far in 2018, the entire Bay Area appears to have shrugged off concerns regarding increasing prices, rising interest rates, stock market volatility and federal tax law changes. We will know more once sales data from the spring selling season starts coming in.

Generally speaking, this is playing out around the Bay Area, but more dramatically in the Tri-Valley area. MSI and Days on Market figures in the Tri-Valley cities are among the lowest in the Bay Area (and the nation), and signify very high demand in comparison to the supply of listings available to purchase.

It is not our intent to convince you of a particular position, but to attempt to provide straightforward data and analysis, so you can make your own informed decisions. Median and average statistics are enormous generalities: There are hundreds of different markets in the Bay Area, each with its own unique dynamics. Median prices and average dollar per square foot values can be and often are affected by other factors besides changes in fair market value. Longer term trends are much more meaningful than short-term. Late-reported MLS activity may change certain statistics to some small degree.
