Aha! There WAS one more sale reported
/Off-MLS, 346 Sound Beach Avenue, $4.285 million. Sellers paid $3.950 for it in September, 2023. Built in 1900, nicely renovated in 2022, it lacks a garage of course — it’s under $5 million — but that’s intentional, to encourage midnight bike traffic from Old Greenwich to Stamford, so the new bicycle path.
