LONG BEACH, CA-An affiliate of Investcorp International Inc. has paid more than $20 million for Park Tower, a 119-287-square-foot building in the suburbs of this port city on the southern edge of Los Angeles County. Although the buyer would not disclose the exact sale price, participating brokers describe the deal as one of the largest of the year in Long Beach.

George Thomson of Lee & Associates Orange represented the buyer. The seller was not disclosed.

Prior to brokering the sale, Thomson was a leasing agent for the building with fellow Lee salesman Marshal Vogt. Together, the pair take credit for raising the occupancy rate of the glass-covered building from 38% to 96% in the 18 months prior to the sale.
