When it comes to seaside quaintness in the Hamptons, Sag Harbor is the ticket, particularly the central historic streets of Sag Harbor Village. Right now, as the season ends and the second-home market suddenly looks dicey, inventory is high—the dots (·) on our map show every one of the 58 homes listed for sale as of press time, in a town of only a few hundred houses. (Brokers say they’re selling briskly, though.) What’s available runs the gamut, from tiny bungalows to private-beach extravaganzas. Here’s a sampling.

71 Jermain Ave.

5 bed, 5.5 bath. $2.595 million. Susan Breitenbach, Corcoran Group.

An expansion and elaborate renovation of a 100-year-old home, with a long heated pool surrounded by fieldstone and terraces right off the bedrooms.
