Executive Summary

We are pleased to present for sale Grand Street Lofts, a 21-unit luxury multifamily property with fully leased ground-floor retail located in the heart of Mamaroneck, New York.

Completed in 2019, the Property features a mix of modern one- and two-bedroom residences with high-end finishes including stone countertops, stainless steel appliances, in-unit washer/dryers, oversized windows, and keyless entry. Residents benefit from an attractive amenity package including a rooftop terrace with a BBQ grill and fire pit, fitness studio, covered parking, package lockers, bike storage, and common area Wi-Fi.

Grand Street Lofts offers investors the opportunity to acquire a newer vintage multifamily asset with embedded rental upside in one of Westchester County’s most supply-constrained rental markets. Current in-place rents remain below comparable luxury properties in Mamaroneck and neighboring communities, providing a clear path for future revenue growth through continued mark-to-market opportunities and operational optimization.

Ideally located in downtown Mamaroneck, the Property is walkable to restaurants, shopping, and Metro-North rail service to Manhattan, while also offering immediate access to I-95 and the Hutchinson River Parkway. Supported by affluent demographics, strong commuter connectivity, and virtually no new competing supply, Grand Street Lofts is exceptionally well-positioned to benefit from continued strength in the lower Westchester multifamily market.
