Commercial real estate investors may still feel some pain in 2011, according to a new report released today by Trepp. Nationwide, the rate of commercial mortgage-backed securities loans that are 30 or more days delinquent climbed to 9.2 percent in December, the highest ever recorded, according to Trepp. Manus Clancy, managing director of Trepp, said that the rocky nationwide delinquency rate was an indication of a rough road ahead in the commercial market.

“Many have speculated that… the commercial real estate crisis was nearing its final stages,” Clancy said. “The December delinquency rate underscored that there still may be some nasty surprises in store even as the market shows some signs of healing.”

Riverton Apartments is at the top of the list of New York City’s commercial properties that are at least 60 days delinquent, by size of loan balance, according to data from commercial loan tracking firm Trepp updated through today. (See full list of delinquent properties — and zoom in on it — here, plus see a slide show of some of the properties above.) Laurence Gluck bought Riverton, the 12, 13-story buildings that lie between 135th and 138th streets and Fifth Avenue and Harlem River Drive, for $135 million in 2005, then refinanced the property with a $225 million mortgage. The foreclosure auction is set for March 11. Other large delinquent properties include Hampshire Hotels & Resorts’ Dream Hotel at 210 West 55th Street, with a loan balance of $100 million, and Time Hotel at 224 West 49th Street, also owned by an affiliate of Hampshire Hotels & Resorts, with a balance of $55 million. Also included on the list are the Meyberry House at 220 East 63rd Street with a $90 million loan balance and and the Core Club retail condominium at 60 East 55th Street, with an $18 million balance.
