Southport Crossing · Office Property For Sale

We are pleased to present Southport Crossing, a 36,142 SF medical and professional office building prominently located at 3530 Post Road in Southport, Connecticut. Anchored by a strong mix of healthcare and office tenants, the property offers a compelling opportunity to acquire a high-quality asset in one of Fairfield County’s most supply-constrained submarkets, with near-term upside through lease-up and rent growth.
The 3-story building is currently 82% leased to a diverse roster of six tenants, with over 67% of the occupied space dedicated to clinical medical use, including behavioral health, physical therapy, and dental practices. Notable tenants include Discovery Mood & Anxiety Program, part of the national Discovery Behavioral Health network, and Lincoln Healthcare Leadership, a well-established healthcare advisory firm headquartered on-site. The current tenancy provides stable in-place net operating income, supported by a 5.1-year weighted average lease term (WALT) and no lease expirations until 2027. With average rents at $30.67 PSF, significantly below the $39.50 PSF submarket average, the property presents clear potential for mark-to-market rent growth. Additionally, the property features robust in-place telecom infrastructure, supporting three long-standing rooftop antenna tenants that generate additional annual income, with existing capacity to accommodate at least one additional tenant.
