1920
Legacy estate set prominently on one of the highest Osterville bluffs delivers classic waterfront expectations with a superior dock and substantial dynamic views from the Vineyard to Hyannisport. The grand yesteryear home constructed in 1920 conveys the qualities of that oceanfront era, with higher ceilings, multiple great rooms, and the character of hidden porches, exclusive balconies, and romantic patios. Curving stone walls, terraced rock feature gardens, and stone patios complement the entire grounds. Across the river from your 200 feet of waterfront is Long Beach, a pristine barrier stretch of powdery white sand and privacy. The dock enjoys some of the deepest water of any house on this stretch, allowing for multiple boats and other recreational craft. The quaint conclusion to this fairytale setting is a larger detached apartment over the garage. The square footage of 9,011, seven bedrooms and seven-and-a-half bathrooms speak for themselves. This treasure is waiting for you.
ADU Potential
Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 7,315 sq ft principal dwelling). Lot size: 60,112 sq ft.
Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
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 MLS and other third-party data may be inaccurate or out of date.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.
