assachusetts reclaims its place in the U.S. luxury housing conversation, with five ZIP codes ranking in PropertyShark’s 2025 100 Most Expensive ZIP Codes list— the only national ranking that relies on actual closed‑sale data rather than asking‑price listings. To qualify, a ZIP must have a median sale price of at least $2 million, a new threshold that underscores the post‑pandemic surge in ultra‑luxury values.
**Massachusetts Highlights**
| ZIP | City | Median Sale Price | Rank Notes |
|-----|------|-------------------|------------|
| 02199 | Boston (Back Bay) | $2.57 M | Returned after a 2024 dip; 7th appearance in 10 years, still about half its 2021 peak |
| 02554 | Nantucket | $2.50 M | Second‑most expensive in the state, despite a 14 % YoY decline |
| 02535 | Chilmark (Martha’s Vineyard) | $2.48 M | New record high |
| 02493 | Weston | $2.39 M | New high, reflecting strong suburban demand |
| 02381 | Wellesley Hills | $2.25 M | Just $50 k below a new record |
These ZIPs illustrate Massachusetts’ blend of urban chic, island exclusivity, and affluent suburbs.
**National Snapshot**
- **Florida’s Rise** – Miami Beach’s Fisher Island (33109) topped the list with a $9.5 M median, up 65 % YoY, marking Florida’s first #1 spot.
- **California’s Dominance** – Eight of the top ten ZIPs and 61 % of the top 100 come from California. Newport Beach’s six ZIPs all made the list; Los Angeles and Greenwich, CT each hold four.
- **Bay Area Contraction** – Though still the largest cluster with 32 luxury ZIPs, the Bay Area’s share has shrunk.
- **Northeast’s Weakest Decade** – New York logged only 15 ZIPs, with just three from NYC. The Hamptons (Sagaponack 11962, Water Mill 11976) remain New York’s luxury hubs. Connecticut surpassed Massachusetts for the first time, contributing a record seven ZIPs.
**Broader Trends**
- Ten ZIPs now exceed $5 M in median sale price, double last year’s count.
- Fifteen states appear in the top 100, mainly coastal and island locales.
- Key ZIPs: 33109 (Miami Beach, FL) – $9.5 M; 94027 (Atherton, CA) – $8.33 M; 11962 (Sagaponack, NY) – $5.93 M; 92661 (Newport Beach, CA) – $5.72 M; 11976 (Water Mill, NY) – $5.5 M; 93108 (Santa Barbara, CA) – $5.24 M; 94970 (Stinson Beach, CA) – $5.23 M; 92657 (Newport Coast, CA) – $5.19 M; 94022 (Los Altos, CA) & 92662 (Newport Beach, CA) – $5.1 M; 92067 (Rancho Santa Fe, CA) – $4.99 M.
These figures reveal California’s continued core dominance, Florida’s rapid ascent, and Connecticut’s resurgence in the ultra‑luxury tier. PropertyShark’s 10th‑year ranking remains the sole authoritative source that uses closed‑sale data to map America’s true real‑estate wealth centers, offering a clearer picture of where luxury buyers are actually closing deals.
