JLL Capital Markets led the financing efforts on behalf of National Development and Benchmark Senior Living for the development of Benchmark at East Islip
New York, Jul. 1, 2026 – JLL Capital Markets announced today that it has arranged $41.1 million in construction financing from a regional bank for Benchmark at East Islip, a 90-unit / 104-bed assisted living and memory care community planned for East Islip, New York.
The financing was arranged on behalf of a joint venture between National Development, a prominent real estate investment development and management firm, and an affiliate of Benchmark Senior Living, a leading senior living provider in the Northeast.
Construction is anticipated to commence on Benchmark at East Islip in July 2026 with completion expected in Q1 2028.
The two-story, 88,000-square-foot community will feature 64 assisted living and 26 memory care apartments across 104 licensed beds. The property will be thoughtfully designed to the highest standards, incorporating premium unit finishes and an extensive array of amenities, including multiple dining venues, a theater, fitness center, salon and a variety of outdoor spaces.
Strategically located within Suffolk County, Benchmark at East Islip will serve one of Long Island’s most attractive residential markets. The community benefits from its proximity to waterfront amenities along the Great South Bay, established neighborhoods and major transportation corridors, including Sunrise Highway, the Southern State Parkway and the Long Island Railroad, providing convenient access to New York City. With the local 75+ population projected to grow nearly 20% over the next five years, Benchmark at East Islip is ideally positioned to meet the expanding demand, while delivering best-in-class service and care.
“JLL conducted a highly competitive marketing process, attracting numerous quotes across a variety of lending sources,” said Jim Dooley, Senior Director within JLL’s Seniors Housing Capital Markets team. “There is no lack of demand in the senior housing sector both from a resident standpoint and an investment standpoint, and new product like Benchmark at East Islip will meet the growing demand in the affluent Suffolk County area.”
