It features updated wood-laminate flooring and a significantly upgraded outdoor living area with a stone-veneer fireplace and TV mount. The kitchen and bathrooms appear functional with ceramic tiling, and the extensive exterior improvements and $50k worth of outbuildings indicate a high level of ongoing maintenance.
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 20370, living area = 1500.
The massive 20,370 sqft lot with rare AR-2 zoning provides a unique opportunity for horse property enthusiasts and significant potential for ADU development.
Includes over $50,000 in value through specialized amenities such as a barn, chicken coop, dog kennel, and a gazebo with a fireplace, ideal for ranch-style living.
With only 1,500 sqft of living area, the home's interior footprint is relatively small compared to the expansive lot size, which may necessitate future additions.
The listing price was recently increased from $839,900 to $869,900, which could potentially limit the buyer pool for a 1960s-era residence in the current market.
