PHILADELPHIA-The Baltimore-based owner puts the 18-story, 435,000-sf office building at 3535 Market St. on the block for an asking price of $195.40 per sf. Located in the University Science Center, it is 93% leased at about $25.50 per sf.

CHICAGO-"Nobody will be happy until it's 95%, 96% or 97% leased," Prentiss Properties Trust president and chief executive officer Thomas F. August says of the company's $87-million investment, but he considers 400,000 sf of space leased since September 2001 to be quite an accomplishment.

GRESHAM, OR-Developer Opus Northwest has four buildings under development at the 54-acre business park, including two build-to-suit industrial buildings and two speculative flex buildings. The two build-to-suit facilities will total just over 100,000 sf and the two speculative buildings will total about 70,000 sf.
