Generally speaking, after years of high appreciation rates, annual 2019 Bay Area median home prices went down a little bit, went up a little bit or basically remained unchanged as compared to 2018. SF hit new quarterly price highs in spring of 2019 (amid all the IPO excitement), but ended up the year at about flat for houses and a little up for condos. (Since there has been so much new luxury condo construction in recent years, year-over-year median price comparisons may not be exactly apples to apples.)
For 2020, economist Ken Rosen at UC Berkeley has said he expects the Bay Area median price to remain basically flat, within a general range of up or down 2% - in other words, similar to what happened last year. We can’t predict the future, but that certainly doesn’t sound unreasonable, and happily avoids the sensationalism of many other media-grabbing forecasts.
