A DEVELOPER'S DREAM in a desirable mid-Island location! On the market for the first time, 126 SAPPHIRE, at the corner of Park Ave, is a treasured family Duplex on a 2,550 sqft lot with original construction reportedly built in1938. Owned by one family for almost 9 decades, modified and expanded over the years with unknown permit history, it is currently improved with two units. The front house consists of a 4 bedroom, 1 1/2 bathroom, 2-story home with 2 kitchen areas and a den. The upstairs rear unit has 3 bedrooms and 1 bathroom. Convenient to Marine Ave shopping and dining, within a short walk to the Balboa Ferry, all that Balboa Island has to offer is walkable, and with less congestion. LISTED SEPARATELY: the adjacent 2,550 sqft parcel at 124 SAPPHIRE, (SEE mls#NP25019868) is a vacant lot with covered storage/patios and open space. Seller’s preference is to sell both parcels (total 5,100 sqft) to the same buyer, thus creating a once-in-a-lifetime opportunity with endless possibilities for the right buyer.
