The real estate agents to the stars and the power brokers who put the deals together recall their most memorable realty moments. The agents were selected by the sheer number of columns in which they have been mentioned.

Stephen Shapiro, Westside Estate Agency:

“Many years ago I sold a house to Joan Collins (house genealogy: Lawrence Harvey, Totie Fields, Max Mutchnick, Collins, Ellen DeGeneres, Ryan Seacrest). After inspections, Joan’s husband renegotiated heavily over a roof replacement and took a credit. They remodeled the entire house and subsequently had a huge housewarming party. It poured that night, and the roof leaked like a sieve and spewed water over the new house. Her husband never used the reduction to repair the roof.”
