During 2019 in the City of Walnut Creek, California, only counting office buildings over 20,000 square feet, there were over 876,596 square feet of buildings sold for a combined sales value of $389,473,000. San Francisco reports that office sales doubled year-over-year. During the third quarter, $2.6 billion dollars of San Francisco office buildings sold totaling 3.3 million square feet. These are huge transfer tax generators and as I have done in the past, caution the various government agencies not to count this a reoccurring revenue stream as this phenomenon is not sustainable in the long run and should not be used for long-term budgeting. Enjoy it while we have it, but at least for the East Bay we have had the majority of our Class A office properties change hands over the past five years, and there is only so much you can squeeze out of an office building, even with rising rents.
