About This Home

49 Washington Avenue

Welcome to this beautifully updated ranch offering the ease of one-level living in the heart of Mastic Beach. Situated on a professionally landscaped .23-acre lot, this 3-bedroom, 2 full bath home combines modern updates, functional space, and exceptional outdoor living. Step inside to find a bright and inviting layout featuring updated finishes and a spacious flow perfect for everyday living and entertaining. One of the standout features of the home is the stunning approximately 300 sq. ft. three-season sunroom overlooking the backyard — the perfect space for morning coffee, relaxing evenings, or hosting guests while enjoying views of the private outdoor setting. Major recent upgrades provide peace of mind, including a brand-new roof completed with a full tear-off, new plywood, and new shingles. The above-ground pool has also been refreshed with a brand-new liner installed this year, making it ready for summer enjoyment. The home also features a fully boarded attic offering exceptional storage capacity — a rare and highly practical bonus for organized living and seasonal storage needs. The beautifully maintained yard offers exceptional curb appeal with mature landscaping, outdoor entertaining space, and plenty of room to enjoy Long Island living. Adding even more value are the incredibly low property taxes at under $6,000 per year before STAR exemptions. Whether you're searching for a move-in-ready primary residence, downsizing to convenient single-floor living, or looking for a home with strong value and updates already completed, this property checks all the boxes. Conveniently located near beaches, marinas, parks, shopping, restaurants, and the Mastic-Shirley LIRR station for an easy commute to NYC, this home offers the perfect blend of comfort, lifestyle, and location.
