The vacancy rate was flat and at a low level in 2015 in the 148,000-unit Oakland-East Bay apartment market, but rents increased faster than incomes. The vacancy rate began and ended the year at 2.7%, with little variation from quarter-to-quarter. In 2015, both the average asking rent increased 6.5% to $1,721 per month, and the average effective rent increased 6.6% to $1,661 per month. The fourth quarter gain was 0.8% by both measures. Overall rents increased 0.1% by both measures in January 2016.
