Office demand started to cool at the end of 2017, but it may be just the beginning for the office market. A recent quarterly report from Savills Studley showed a drop in office leasing activity at the end of last year. The slowdown also led to a decline in investment sales, and has encouraged some investors to look outside of the California market for opportunities. This year, expect to continue to see office activity slow as a result of slow employment growth, corporate restructurings and an increase in sublease space.
