Linder, 56, founded The Linder Co. in 1982, developing it from a one-man real estate brokerage into a 40-person operation with offices in three states. He sold the company, now known as Sitehawk Retail Real Estate, three years ago.
"He was a real student of the business, one of the original veterans in this industry," said Mark Perlstein, who became Linder's partner in 1988. "He was very detailed, extremely intelligent and very kind and giving to people in need."
Linder had a keen vision and he executed it well, Perlstein said. One of his most prominent projects was the redevelopment of Merchant's Square in Carmel, which turned a mostly vacant shopping mall generating sales of $17 per square foot into a thriving center with more than $300 per square foot in sales.
"He taught me everything I know in this business," Perlstein said. "I won't forget that."
Linder died of a brain aneurysm, Perlstein said.
He is survived by a son, Ben, a daughter, Alyssa, and a sister, Sharon Linder.
A service is planned for 10 a.m. Sunday at Aaron-Ruben-Nelson Meridian Hills Mortuary, 1328 W. 86th St.
