From the moment you arrive, you'll appreciate the fresh exterior paint, inviting front porch, and thoughtfully landscaped grounds. Inside, the home has been extensively remodeled with new plank flooring, fresh interior paint, recessed lighting throughout, new sheetrock, dual-pane windows, new interior doors, and new front and rear entry doors. The stunning kitchen serves as the centerpiece of the home, featuring designer-painted wood cabinetry, elegant gold hardware, a gold designer faucet, stainless steel appliances, and beautiful Carrara quartz countertops that create a timeless and sophisticated space for cooking and entertaining. The remodeled bathroom showcases modern luxury with a striking blue vanity accented by gold finishes throughout, including a gold-framed mirror, gold faucet, gold towel holders, gold toilet paper holder, and coordinating gold hardware that beautifully tie the space together. Major infrastructure improvements provide peace of mind, including replacement of the original knob-and-tube wiring with new electrical wiring and a new electrical panel, a new furnace, new HVAC ductwork, and a tankless water heater for energy-efficient living. The spacious primary suite is a true retreat, featuring vaulted ceilings that create an open and airy atmosphere, abundant natural light, and ample space for a sitting area, home office, or reading nook.
