The property

Cedar shingle, a heated gunite pool and a pool house, set between farm fields and a quarter mile from the ocean. Rents Memorial Day to Labor Day.

Provenance

On land farmed by the same family from 1890 to 1998. The house was designed by a Bridgehampton architect in the manner of McKim, Mead & White's 1880s cottages.

Risks we weighed

Rates a point higher, a month more vacancy and values two points lower take the ten-year IRR to -3.9%. Flood exposure is minimal.
