45 Seth Lane, South Yarmouth, MA

Every day at 45 Seth Lane feels like a vacation, where mornings rise with the tide and dawn paints soft light across Bass River. Set on 1.37 acres of vibrant gardens and green space with 288 feet of private river frontage, this 5-bedroom, 5.5-bath estate blends classic Cape Cod charm with modern comfort, where nearly every room is intentionally designed to capture panoramic river views. The sunlit river room and first-floor primary suite with new radiant-floor spa bath offer restful retreats, while updates—including a new Jack & Jill bath upstairs, a new full bath on the main level, and central air brings comfort to every season. From the licensed dock with water and electricity, you can slip into tranquil mornings of kayaking or paddle-boarding, or head out by boat to Nantucket Sound. Afternoons invite barefoot walks on the lawn, reading on the deck as boats drift by, or moments of stillness at the water's edge. Evenings end with sunsets awash in rose and gold, setting the stage for intimate dinners or quiet reflection. Treasured for its natural beauty and serenity, this rare waterfront estate offers more than a home—it is an enduring retreat into the timeless beauty of Cape Cod.
