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.
