After testing the waters with a few individual apartments, Prudential Douglas Elliman’s Lenny Sporn and Mickey Roth have listed all of the remaining sponsor units in 370 East 76th Street as a $26 million bulk purchase. The package includes 55 units totaling 48,355 square feet, Roth said. He said both the individual units and the package, which became available last week, have seen interest. Several current tenants of the 366-unit co-op are considering putting their units on the market as part of the package, Roth said, and others are interested in buying additional units in the building, owned by East 76th LLC.
