About this home
Unbelievable opportunity for anyone looking for a one of a kind project with terrific upside and development potential. Nearly 1/2 acre of sprawling level land, zoned multi-family, but could allow for multiple lots. Check with county on SB9 guidelines. Main house has good bones and recent roof per inspector, 4 br's/ 3 Ba's of 1853 sq ft but needs complete updating inside. I say, fix it up, move in, then sit on the back patio to gaze out at your beautiful big yard to decide what to do next! Second house is measured at 657 sq ft but is NOT included in the house sq ft. It is accessed by its own driveway on the right, which is on a separate parcel, included in the sale. It's set perfectly at the very back of the property and has two rooms and its own 1 full bath, but is in serious disrepair and being sold without warranty. It was lived in for many years by the original family and also has a recent roof, but is likely a major fixer or tear down. All reports on file. Very short opportunity to see this before its gone.
