A NEW FURNACE anchors the appeal of 14-20 Grove Street, a hard-to-find legal four-family in Plainfield's Wauregan village. Set on 0.54 acres with approximately 3,682 square feet, the property offers two three-bedroom and two two-bedroom apartments, each with a washer and dryer. One unit features new kitchen flooring. Vinyl siding and an unfinished basement complement the property. Three occupied units generate $4,700 monthly in gross rent, or $56,400 annualized. Leasing the vacant fourth unit at a projected $1,750 monthly would bring scheduled gross income to $6,450 per month, or $77,400 annually-$21,000 in potential additional annual revenue without increasing existing rents. Reported 2026 taxes: $4,397. Existing income and a clear lease-up opportunity make this Windham County property worth a closer look. Projected rent is not guaranteed. Gross income excludes expenses, vacancy and collection losses. Buyer to verify details. Home to be sold as-is.
