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 ranch blends timeless character with meaningful recent upgrades. Inside, newly refinished hardwood floors run throughout, gas insert fireplace, efficiency replacement vinyl windows installed throughout the home. A generous 4-season sunroom addition, built 11 years ago, has its own mini-split heating and cooling system, and offers a bright, flexible multi-use space, perfect for entertaining, family gatherings, and a year round retreat. Major systems have been thoughtfully updated for peace of mind: a gas furnace and central air installed 1 year ago. Plumbing has been installed to provide main level laundry and is easily accessible to convert 1 of the bedrooms into a spacious 2nd full bathroom with laundry. This home offers plenty of room to grow, entertain, or work from home. This is a rare opportunity to own a true one-owner meticulously kept home in one of the Capital Region's most desirable school districts.
