Start with what the record actually says. Per Miller Samuel’s second-quarter numbers for Douglas Elliman, the East End logged 425 sales against 1,166 listings, inventory down 9.5% in a year and nearly 16% below its ten-year average. The market’s center of gravity, the $1M–$5M band, posted a $2.2 million median, up 16.1% year over year. Sales under $1 million have thinned to 14.6% of the market, a near-record low. In 2005, the overall median was $735,000. The Hamptons did not get more crowded; it got more expensive and more exclusive at the entry.

None of that is a reason to leave. It is a reason to know precisely what staying costs, and what the same capital does in markets built on the opposite tax logic.

The verdict

The Hamptons is the better place to summer. The Southeast is the better place to be taxed. The household that wins is the one that decides which of those two sentences is doing the heavy lifting in its life, and stops paying full price for the other one.

Leaving is wrong for you if

Your income is made in New York rooms that require your presence; your family’s gravity is within two hours of the Long Island Expressway; or the specific Atlantic light of an August evening in Amagansett is, on reflection, what the money was always for. Then stay, and stop reading letters like this one.

Staying is wrong for you if

Your work went remote and never came back; your carry, taxes, insurance, and upkeep now buys a second life somewhere else every single year; or your estate is drifting toward a $7.35 million cliff that four Southeastern states simply do not have. Then the East End is a place to visit, beautifully.
