With the mansion market growing ever hotter, Palm Beach County agents were among some of the most productive in the nation last year, according to the annual RealTRENDS/Wall Street Journal ranking.

Topping the list was Paulette Koch of Corcoran Group in Palm Beach. She handled sales totaling $234 million, 21st in the nation. Her average sale price was $5.5 million.

Koch, who often shares listings with her son, Dana Koch, had a part in the largest sale on the island last year, a $42.9 million sale of three properties in the 500 block of South Ocean Boulevard and 61 Middle Road. Koch’s production soared from $88 million in 2013, according to the ranking.

Second among Palm Beach County brokers was Christian Angle of Christian Angle Real Estate in Palm Beach. He handled deals totaling $219 million last year, up from $202 million in 2013, when he was the county’s top agent.

Other $100 million producers among Palm Beach County agents and their national rankings:

34. David Roberts, Royal Palm Realty, Boca Raton: $201 million

43. Cristina Condon, Sotheby’s International Realty, Palm Beach: $171 million

58. Carol Sollak, Engel & Volkers, Wellington: $148 million

83. Pascal Liguori, Premier Estate Properties, Delray Beach: $120 million

85. Jim McCann, Corcoran Group, Palm Beach, $118 million

93. Rob Thomson, Waterfront Properties, Jupiter: $113 million

122. Candace Friis, Corcoran Group, Delray Beach: $101 million

Carole Ruhlman of Sotheby’s International Realty didn’t crack the $100 million mark, but she did boast the highest average sale price in Palm Beach County, at $9.9 million.

The ranking also rated agents by volume. Corey Edwards of Keller Williams in West Palm Beach followed a hectic schedule to dominate on that measure, handling 164 “transaction sides” — the buyer and seller each count as a side.

“When we go on vacation, unfortunately, I’m working,” he said.

Unlike the Palm Beach mansion brokers, Edwards handles lower-value properties. His website shows three condos priced at less than $30,000.

“We take anything,” Edwards said. “A few times a month, we get a bigger transaction, and that makes up for the smaller ones.”

Edwards said a shift away from foreclosures means he’s looking for new sources of business. So he’s buying Internet leads and expanding into Fort Lauderdale.

“I kind of consider myself a chameleon,” he said. “When the color changes in the room, we change with the environment.”
