We took this of Centergy One (the 488K SF office tower at Fifth and Spring streets) because we found out last week that its owners, Kim King Associates  and Gateway Development, are putting it on the market (or at least the 253K SF portion not owned by Georgia Tech's  University Financing Foundation). It's being repped by CBRE's Will Yowell  and Justin Parsonnet. While the offering just hit the investment community, Justin tells us interest in the property is already significant. Tenants in the 99% leased building include RBC Centura, Accenture, and the Georgia Department of Economic Development. ?The demand drivers related to the school make it a very different play,? Justin tells us. That's not the only high-profile office project hitting the market. Fresh from renewing CryoLife  for more than 11 years in its Kennesaw  campus, Pope & Land is bringing the company's HQ to market with CBRE as well. Pope & Land originally developed the 200K SF building at 1655 Roberts Blvd. for the biotech company, the firm's Mason Zimmerman tells us.
