Corporate Office Properties Trust (COPT) is seeking to sell majority of the properties. COPT has also begun marketing 16 of its 21 properties including its five buildings in the Patriot Park business park and six buildings in the north side InterQuest business park. COPT executive declined to talk with The Gazette but said in conference that the sale of the properties could fetch $160 million, although it was unclear if that figure also included some assets outside of the Springs.

"We believe we know who, not who the buyer will be, but the type of buyer, and we've got a good package ready to go," executive added.
