Sibag, Siemens' real estate division, is banking on CB Richard Ellis Inc. to come up with a sales price of at least $184 per sf ($75 million), the price Siemens paid for the asset in 1994.

But area brokers familiar with the Cumberland Mall office submarket tell GlobeSt.com on condition of anonymity Siemens will be lucky to get $170 per sf ($69 million) in a currently low appreciation phase of Downtown office assets.

Brokers base that assessment on the April sale of another Downtown icon, the three-tower, 900,000-sf Atlanta Financial Center purchased by Hines Interests Inc. of Houston and General Motors Asset Management for $154 million or $171 per sf.

Still, brokers tell GlobeSt.com Cumberland Center II has a strong cash stream going for it with its 100% leasing mark and a strong anchor in Sprint Corp. Sprint occupies 240,000 sf or more than half of the class A asset on a lease that expires in 2006. Another tenant, Sita, an airlines data network company, extended its lease for 150,000 sf to 2004.

"Getting your money out of a high-profile asset such as this one where the owners may have overpaid seven years ago could be a real challenge in this economic climate," a Downtown broker tells GlobeSt.com on condition of anonymity.

CarrAmerica Realty of Washington, D.C. leases and manages the building.
