Overview

Investors take notice: Rarely available in Higganum, this three-family property (previously a 4-family and easy conversion back to a 4) offers a unique opportunity for an owner-occupant, investor, or those looking for flexible multi-generational living. Set in one of the Connecticut River Valley's most desirable small-town communities, the property combines multiple living spaces with convenient access to Route 9 for commuting to Middletown and beyond. Enjoy everything that makes Higganum and Haddam such a special place to call home-from hiking and exploring the trails of Cockaponset State Forest to kayaking, fishing and relaxing along the Connecticut River and nearby Haddam Meadows State Park. Local farms, seasonal markets, community events and nearby destinations including Goodspeed Opera House add to the area's unmistakable New England character. Located within the highly regarded Haddam-Killingworth school district, Higganum offers that hard-to-find "big enough small town" lifestyle-plenty to see and do, yet still a community where you can feel connected. Three-family properties are rarely available in this area, making this an opportunity worth exploring whether you are looking to live in one unit while generating rental income, expand your investment portfolio, or create a property that works for multiple generations. This property will be sold AS-IS. This is currently a 3-family property that can be converted back into a 4-family home if desired.
