Don Jergler Average rent in Long Beach is expected to increase more than 6 percent and occupancy rates are expected to rise in the next year, according to a report by the Casden Real Estate Economics Forecast from the University of Southern California Lusk Center for Real Estate. "With very little new supply and the general tightness of the market, the occupancy rates are moving up and the rents are moving up with it," said Delores Conway, director of the Casden forecast.
