Rumson.

Rumson is what Greenwich was thirty years ago — a quiet shingle-style enclave on a Navesink peninsula, where the prep schools (Rumson Country Day, Ranney) feed Princeton and Brown, and the streets are lined with sycamore trees that arch over private driveways. Median holds at $2.7M because supply is structurally constrained: the township is small, the zoning is restrictive, and inheritance keeps homes off the market for generations.

It's the address that signals 'old money' to buyers who know — Bruce Springsteen kept his property here, Jon Bon Jovi grew up two towns over, and Wall Street has always treated Rumson as a quieter alternative to the Hamptons. Heritage House Sotheby's is the dominant brokerage, but Christie's International Real Estate Group has been quietly building a presence — and Mirtha's bilingual representation is rare here.

Rumson rewards patient buyers. The right shingled estate on Bellevue Avenue surfaces twice a decade. Mirtha represents the family that wants the address but doesn't have generational ties — the bilingual buyer arriving from Bogotá or Madrid or Manhattan who needs a guide fluent in two cultures, not just two languages.
