The great advantage of reviewing annual data is how often the market trend lines clarify into a straightforward dynamic, instead of the constant up and down fluctuations often seen in monthly or quarterly data charts. (Monthly data is constantly being abused by the media, when proper context is not given.) It is similar to standing back to look at a broad view of terrain as opposed to focusing on the one small piece that is right in front of your shoe.
Among other advantages, annual trend lines track greater amounts of data, which usually adds to reliability, and also avoid the fluctuating effects of seasonality on real estate markets. However, we also have dozens of charts that look at monthly and quarterly data, sometimes specifically to illustrate seasonality, but those analyses are in other reports.

S&P Case-Shiller Bay Area Home Price Index Trends
Case-Shiller does not use median prices to determine appreciation, but instead uses its own proprietary algorithm. The numbers on Case-Shiller charts refer to home prices when compared to a January 2000 home price of 100. Thus if at some point after 2000, the chart number is 150, that signifies 50% home price appreciation since January 2000. Case-Shiller uses a 5-county metro area in its San Francisco analyses. Needless to say, this includes a huge variety of different housing markets.
We probably have 10 charts illustrating Case-Shiller data. This one below breaks out appreciation and depreciation trends by price segment, dividing the market into thirds by number of sales. The reason why this is particularly important recently is that during the subprime bubble and the resulting crash, different price segments had bubbles, crashes and recoveries of hugely different magnitudes, mostly depending on how they were affected by subprime financing, foreclosures and distressed property sales.

Annual General Market Dynamics Trends
Looking at annual trends of a variety major real estate market measures, one is struck by how the different analyses reflect virtually the exact same market dynamics over the past 6 or 7 years, heating up as the market came out of the recession, and then cooling or plateauing in 2016 after market heat peaked in 2015. When multiple statistics line up like this, the data is considered much more meaningful and reliable. However, remember that the San Francisco and Bay Area markets are made up of many distinct segments, and it’s not unusual for the trends in specific segments (prices, locations, property types) to, at times, go in different directions at varying speeds.
Depending on the statistic, a trend line moving up might signify either a market heating up or one cooling down, and vice versa.

It is impossible to know how median and average value statistics apply to any particular home without a specific comparative market analysis, which we are happy to provide upon request.
These analyses were made in good faith with data from sources deemed reliable, but may contain errors and are subject to revision. 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 San Francisco and 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.
