Year-round lakeside living on Sebago! This charming cottage is located in the highly sought-after Northwest Shores Association and features a new 40' Duralite aluminum dock with ramp and handrails that safely leads from your boat to the waterfront terraces where you can relax at the water's edge. The property's shore has been secured by a recently engineered and professionally installed seawall. And, as part of the Association, you can enjoy the use of the nearby private sandy beach and keep your boat safe during any storms at your boat slip in the protected harbor, easily accessed just a few lots away at the end of South Beach St. Originally built in 1955 by the owner's grandfather, this home has remained in the family and has been lovingly maintained and improved over the decades. Whether you're finding respite in the shade of the mature oak tree on the home's newer side deck (creatively built around the tree's base) or watching the sunrise from the perched view, you'll quickly realize that 18 South Beach is a special place. Upon entering the home, you are greeted by the sunroom with vaulted ceilings and expansive lake views - this will be your new favorite spot! The main living area, with original tongue and groove pine, offers a cozy yet open feel, and the eat-in-kitchen flows to the living area with a niche and wall of built-in bookshelves. Down the hall are the renovated full bath and the bedrooms with pocket doors and large closets to maximize the sense of space. A spiral staircase leads to the full, unfinished basement which has both a front door to the waterside and double doors to the attached carport. With a laundry area and additional egress by numerous front and back windows, this basement offers the potential to expand your finished square footage. The owners have completed many recent updates including newer roof, windows, flooring, plumbing and electrical updates, furnace and oil tank, and new septic system. Enjoy summer of 2024 on Sebago Lake!
