Exceptional development opportunity in the Village of Monticello, Sullivan County. This 4.77-acre parcel with nearly 500 feet of frontage on Rock Ridge Avenue is ideally suited for a residential subdivision. Preliminary concepts suggest the potential for up to 12 lots on a cul-de-sac, each capable of supporting semi-attached two-family homes, creating 24 to 30 units in total. R-2 zoning permits one- and two-family dwellings, and municipal water and sewer are reported to be available nearby (buyer to verify with village). The property currently includes an existing single-family home that can provide rental income during the subdivision and approval process, making this a rare opportunity to offset carrying costs while entitlements are pursued. An additional opportunity is available directly across the street with a 2.45-acre parcel (MLS #906525), which may support 10 to 14 single-family homes, offering even greater development potential if purchased together. The location offers convenient access to Route 17, Resorts World Casino, Kartrite Waterpark, Bethel Woods, shopping, dining, and schools, all within the rapidly growing Catskills region. Buyers, builders, and investors will appreciate the strong demand for new housing in this area. Buyer must perform all due diligence and confirm zoning, subdivision potential, utilities, and approvals with the Village of Monticello, the Planning Board, and local governing authorities.
