About this home

A fix and save classic. Original house in fabulous Porter Ranch neighborhood has been left to the heirs and will be sold in its current condition. Needs nearly everything you can think of except pool refurbish, which has been maintained. Sweeping corner lot w/ circular drive, 3 car plus RV access, 4BRs up plus study down, family room, formal dine, large BK area, central vacuum. Large covered patio, sparkling pool and oversized spa, damaged sports court could be huge lawn area for new buyer. Balconies off three bedrooms w/ pleasant view. Master has walkin. Amazing potential for buyer that wants location and good future value for today's low price. No pet smell or clutter, just old, dated and original home of a wonderful couple that have since passed.
