When Mark Twain famously said, ''Buy land; they're not making it anymore,'' there was still plenty to choose from. Today's shrinking inventory of buildable lots adds urgency to Twain's advice - especially when the land is surrounded by captivating scenic coastline. Such is the case with 736 Seashore - which happens to be the last known buildable lot on the sought-after back shore of Peaks Island. The 1.2 acre +/- parcel is just steps from the active surf and the beach at Spar Cove. Bring your designs/plans/ideas (along with your swimsuit /sand chair/kayak) and take advantage of this rare opportunity to build your dream home! Existing well, septic design available (may need updating). Peaks Island is located just 15 minutes from Portland's Old Port.
