Welcome to 21 Cornelison Avenue – A Rare, Expansive Income-Producing Gem in the Heart of Nyack
Step into what feels like your own private estate—this striking colonial-style triplex sits on a beautifully landscaped 0.29-acre lot with wraparound porch charm, timeless stucco exterior, and over 3,000 sq ft of living space. With two large units (2-bedroom + 5-bedroom) across three spacious levels, this home is ideal for live-in landlords, multi-generational setups, or savvy investors looking for strong rental potential in one of Rockland’s most desirable villages.
Inside, you'll find bright, oversized rooms, hardwood floors, and a flexible layout that includes multiple living and dining spaces, a windowed eat-in kitchen, and plentiful storage throughout. The second and third floors function like a private duplex with 5 bedrooms, a walk-in closet, and beautifully proportioned entertaining space. The main floor includes a separate 2-bedroom apartment with its own entrance—perfect for extended family or steady rental income.
This property offers incredible flexibility with room to customize or expand, and is within walking distance to downtown Nyack’s shops, restaurants, parks, and riverfront—making it as attractive to tenants as it is to owners.
