Rare opportunity to own a grandfathered, buildable 5,000 sq. ft. non-conforming residential lot in Belmont Hills, within the award-winning Lower Merion School District. 138 Rockland Avenue is recognized by Lower Merion Township as a legal single family building lot (buyer to confirm all zoning and permitting requirements). This lot, held by the same family for generations, is being sold by the owner of the adjacent property at 140 Rockland Avenue, whose existing driveway encroaches approximately 810 feet onto the lot. The seller wishes to retain parking rights, which the buyer will need to address through a mutual easement agreement and by adding a driveway on the opposite side of the lot. The property is being sold as-is, with the buyer responsible for all due diligence regarding township approvals, permits, or easements. This is a unique opportunity to build a new home at an entry-level price point in Lower Merion Township on a quiet, lightly traveled street with easy access to I-76, Manayunk, and Center City, and just a short walk to Belmont Hills Elementary, McMoran Park, the public library, and the community pool.
