Welcome to 843 Warner Rd, a lovingly maintained 4-bedroom, 1-bath home offered by its original owner for the very first time since it was built in 1955. Set on a spacious lot in the sought-after Niskayuna School District, this 2,111-square-foot home blends timeless character with meaningful, recent upgrades. Inside, hardwood floors run throughout, gas insert fireplace, efficiency replacement vinyl windows installed throughout the home. A generous sunroom addition -- built roughly 10 years ago with its own mini-split heating and cooling system -- offers a bright, flexible space perfect for a home office, playroom, or year-round retreat, independent of the main house's HVAC. Major systems have been thoughtfully updated for peace of mind: a gas furnace and central air conditioning system installed just 1 year ago. Roof approximately 10 years old. With 4 bedrooms, this home offers plenty of room to grow, entertain, or work from home. This is a rare opportunity to own a true one-owner home in one of the Capital Region's most desirable school districts.
