The Rreef purchase is being applauded by local real estate brokers. "I think it speaks positively about the market," Ron Urgitus, who handled the sale with fellow CB Richard Ellis brokers Tim Swan and John Marold, tells GlobeSt.com. "You've been hearing a lot of negatives comments on the real estate market recently. I think this shows the willingness of buyers to look at Denver, both in terms of short-term and long-term. This is good news for the market. People have been waiting for somebody to step in and be proactive."

Brad Neiman, who heads investments for Denver-based Mile High Properties, which was not involved in the sale, agrees. "It was an unusually high valuation given the current climate," Neiman tells GlobeSt.com. "Certainly, it must speak to Rreef's faith to their Denver market and their positive expectations in leasing the market. These are challenging times right now."

Neiman says any money that TeleTech lost on the sale, it "certainly made up for it on the buy they made for the AT&T Broadband building in Meridian."
