Howard Greenberg, a partner with DeMarzo Realty, recently co-brokered an $11.5 million sale of a property on the final day of the buyer's 1031 exchange period-less than a month after joining the seller's brokerage team, working with the exclusive broker Vanessa DiCarlo. Notably, the contract closing also took place on the day of the signing. The property, a free-standing garage building at 506-10 West 181st St., near Yeshiva University in Inwood, was sold by 506-10 West 181st St. LLC, and bought by MICL LLC.
