Set on a beautifully landscaped and remarkably private 0.84-acre lot in Greene Countrie, this spacious 4-bedroom, 2.5-bath Colonial offers approximately 3,452 square feet, a traditional floor plan, and an exceptional opportunity to create a home tailored to your own style. The welcoming center-hall foyer is framed by substantial woodwork, beautifully maintained hardwood floors, and plantation shutters found throughout the home. A formal dining room sits to the left, while the generously proportioned living room to the right features a fireplace and windows on multiple sides. The spacious kitchen offers abundant cabinetry, granite surfaces, a large center island, and a professional-style gas range. An adjoining breakfast area provides ample room for everyday dining and opens directly to the deck. Just beyond the kitchen, the inviting family room features exposed beams, a striking stone gas fireplace and views of the surrounding greenery. The family room leads to a three-season room with a vaulted wood-paneled ceiling, tiled floor and walls of glass overlooking the wooded setting. Multiple doors open to the expansive deck, creating an effortless connection between the home and its peaceful outdoor spaces. A separate first-floor office provides a quiet and versatile place to work, read or pursue hobbies. Upstairs, the spacious primary suite includes a private bathroom, while three additional bedrooms—one currently arranged as an office—share a full hall bath. Generous closets, hardwood flooring through the hallway and abundant natural light add to the home’s appeal. The large unfinished basement provides excellent storage and significant potential for future recreation, fitness, workshop or additional living space. Outside, mature trees, established plantings, stone garden paths and layered landscaping create an unusually private setting. The expansive deck offers multiple areas for dining, entertaining or simply enjoying the surrounding landscape. Built in 1975 and carefully maintained by its longtime owners, this home offers generous room sizes, quality hardwood floors, distinctive architectural details and a beautiful setting.

Recomputed from the county assessment ($590,480, 2021 base year) × current millage. School millage is from the latest year certified by the Pennsylvania Department of Education (2025-26); districts adopt the next year's budgets each June, and we update when the state certifies the statewide file in the fall. Portals typically reprint the recorded 2026 bill. Pennsylvania does not reassess on sale. Estimate only. Verify with Delaware County before relying on it.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
