Welcome to 137 1st Ave., a beautifully updated 4-bedroom, 2-bath American Foursquare in the heart of Red Lion Borough that strikes the rare balance of full modernization with the original architectural details that make these homes timeless. Step onto the wraparound covered front porch and through the front door into a sun-filled living room with a tiled fireplace, refinished hardwood floors, and original wood trim. A defining oak colonnade with built-in glass-front china cabinets opens into a generous dining room framed by leaded-glass windows and original wainscoting. The renovated eat-in kitchen offers quartz countertops, stainless appliances, a deep single-basin sink, subway tile backsplash, and patterned tile floors, plus a first-floor full bath and laundry tucked just off the kitchen for everyday convenience. Upstairs you will find four true bedrooms, a renovated full bath with marble-look tile and matte-black fixtures, and a primary with its own walk-in closet. Major systems and exterior have been dialed in with a brand-new roof, brand-new high-efficiency HVAC providing heat and central air, and a freshly redone driveway. The full unfinished basement adds excellent storage with walk-out steps for easy outside access, and the expansive unfinished third-floor attic offers tall ceiling height and the footprint to add a bonus suite, office, or studio down the road. Outside, a side carport and a large detached garage handle parking and storage with room to spare. Walking distance to downtown shops, restaurants, parks, and everything else Red Lion has to offer.
