Contractors special, this home and lot (26,000SF) has tons of potential. Per the City, this lot is allowed to add a guest house and a detached garage and a barn and a shed, all four! Zoned for two horses, the city also allows for a mixture of animals in multiples. The property already has a great add on with the converted garage to a huge step down family room and an over sized car port. The new added bedrooms are huge and the master is enormous. Back door from the master leads out to the pool or you can exit the kitchen pantry area next to the front bath out to the pool. Yes the kitchen and baths need updating and that is reflected in the price. Local listings are asking 1,000,000.00! Gated front yard is safe for kids and pets, plus ample parking outside the gate and wall in front of the house for convenience coming and going.
