About this home

Prime first-floor professional office condo in the historic Old Stone Building in Mahopac. This well-maintained suite features two private entrances, two bathrooms, and a versatile layout suited for a wide range of professional uses. At present, the unit functions as a single professional office suite. However, the floor plan offers the flexibility to be reconfigured into two independent office spaces should future requirements call for it. This property is part of a small five-unit office condominium, where the owners have established a monthly fee to maintain the building, covering routine upkeep and shared operating expenses. In addition, the owners collectively split the cost of any major repairs, ensuring the building remains well cared for and professionally managed. The condo is currently leased to a long-term, reliable tenant who wishes to remain, providing immediate stability and income for an investor or owner-occupant. A rare opportunity to own a flexible, income-producing professional space in one of Mahopac’s most recognizable buildings.
