Nearly 4,000 square feet. Seven bedrooms. Five full bathrooms. 662 18th Avenue brings uncommon scale to Irvington's new-construction two-family market. The four-bedroom duplex features an expansive 23-foot living room, oversized kitchen with generous island, first-floor bedroom, 3.1 baths and a remarkably spacious primary suite with en-suite bath and walk-in closet. Multiple walk-in closets and dedicated laundry add practical storage and convenience. The second residence offers three bedrooms, two full baths, its own laundry and a well-appointed kitchen with quartz surfaces, stainless steel appliances and island seating. Throughout the home, contemporary finishes, central heating and air conditioning, recessed lighting and abundant natural light support everyday living. A one-car garage plus parking for additional vehicles provides valuable off-street parking. Additional benefits include a pre-installed ADT security system, builder-provided 2/10 Home Owner's Warranty and eligibility for Irvington's five-year tax abatement. This property is eligible for CRA loan programs offering below-market interest rates and no borrower-paid mortgage insurance, subject to borrower and program requirements. For an owner-occupant, the second residence offers income potential while preserving the space and privacy of a substantial home.
