REAL ESTATE

Rockefeller Center Bids Evaluated: The real estate trust that holds the $1.3-billion mortgage on New York’s landmark Rockefeller Center has put one bidder on hold as it evaluates two proposals from rival bidders, one of them a group that includes David Rockefeller. Rockefeller Center Properties Inc. said it decided against exercising its right to sell $10 million of common stock to a group led by Chicago investor Samuel Zell, whose group has agreed to invest $250 million for a 50% stake in the trust. The trust also said its advisers will consider other proposals. Goldman Sachs & Co., real estate firm Tishman Speyer & Co., and David Rockefeller late Sunday offered to buy the real estate trust for $296 million.
