Find your Tidal Fix in the heart of Harwich Port. Just moments from the warm waters of Nantucket Sound and approximately .3 miles from the shops, restaurants and unmistakable energy of the village, this classic Cape cottage captures the character of summers by the sea while offering the modern comforts today's buyers appreciate. A welcoming full-width porch sets the tone, with water views and a front-row seat to the rhythms of this special coastal neighborhood. Inside, the home retains the 'vibe' that makes vintage Cape cottages so enduring, complemented by a series of thoughtful updates. The main level offers an inviting living room, dining area, kitchen with updated appliances and flooring, laundry, and a beautifully renovated full bath with glass-enclosed shower. Upstairs are three bedrooms along with an additional flexible room, providing options for guests, a home office or additional living space. Recent improvements include updated heating and cooling, an instant hot water system, newer appliances, fresh interior paint, updated lighting, a new front door and screen doors, and refreshed landscaping with irrigation. Outside, a private side yard creates an easy extension of the living space with room for dining, grilling and summer afternoons, while the enclosed outdoor shower is an essential Cape Cod finishing touch. The home has also enjoyed several successful seasons as a vacation rental, offering the next owner the flexibility to use it purely as a personal retreat or continue taking advantage of its established appeal to summer guests. And then there is the location. The beach is approximately 150 feet away, making morning swims, afternoons by the Sound and evening trips back to the water part of everyday life. With Harwich Port Village so close, days here unfold with remarkably little need for a car. Charming without feeling precious and updated without losing its original character, Tidal Fix offers a rare opportunity to own a true Harwich Port cottage in one of the village's most desirable seaside settings.

Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
