A buyer walked through a two-bedroom cottage a block off 96th Street last winter and left thinking the asking price made no sense. The kitchen was original. The bathroom needed everything. Then the agent walked her past the lot two doors down where a new build was going up on what had been an identical footprint a year earlier, and the number started to make sense. She wasn't buying a kitchen. She was buying a piece of one of the most contested lots on Seven Mile Island, and the house sitting on it was almost beside the point.

That's the thing about shopping for a home in Stone Harbor. The median price you saw online before you started looking doesn't describe a market. It describes four of them, mashed into one number, and knowing which one you're actually standing in changes how you should read every listing that follows.

One Median, Three Sales

Start with the number itself. In January 2026, Redfin recorded a median sale price of $3.3 million across Stone Harbor as a whole. In that same month, in the pocket Redfin classifies as Downtown Stone Harbor, the median was $890,000. Same island, same 30 days, a nearly four-fold gap.

Part of the reason that gap can swing so wildly month to month is that the sample size is tiny. Redfin counted just three closed sales in Stone Harbor that January, down from eight the year before. When your entire monthly dataset is three houses, one large bayfront closing or one modest interior sale can move the median by hundreds of thousands of dollars. That's not a market producing a single, stable price. That's three rows in a spreadsheet.

The number keeps shifting depending on who's counting and how. Movoto reported a median sold price of $4.599 million in June 2026, on 57 closings that month, up from 42 the year before. By September 2026, Movoto's tracked median list price had eased to $4.25 million, with homes typically sitting about 101 days before going under contract. Zillow's home value index, a different measure entirely that averages estimated values rather than closed sales, put the average Stone Harbor home value at $2,481,688 as of March 2026, up 7.3 percent year over year.

None of these numbers are wrong. They're measuring different slices of a market that doesn't behave like one thing, which is exactly the point.

The Island Is Actually Four Markets

Every one of those figures reflects properties that trade on almost entirely separate logic:

• Interior and downtown blocks, where older cottages and smaller lots still change hands for what looks, by shore standards, like a normal home price
• Bayfront parcels, priced for water access and protected marsh views rather than square footage
• Oceanfront lots, where flood-zone rules can shape what may be rebuilt
• New construction, which on a fully built island means nearly every new listing started as a teardown

A buyer comparing a listing in one category to a listing in another using the borough-wide median is comparing apples to a very expensive orchard.

The Bay Costs More Than the View

Bayfront lots in Stone Harbor were valued around $100,000 in the early 1990s. Brokers who specialize in the waterfront market now put those same lots at $3 million to $6 million, depending on size and location. There's a saying on the island: "anyone can go to the beach, but you need an invitation to the bay."

The premium isn't only about the water. The Stone Harbor Bird Sanctuary sits inside town limits, the Wetlands Institute is up the road, and the protected preserve at Stone Harbor Point keeps the southern tip of the island wild. For a bayfront owner, that's a structural fact rather than a scenic one. A meaningful share of the marsh and channel view in front of a bayfront home is part of what a buyer is paying for, along with the dock, the boat slip, and whatever bulkhead maintenance comes with it.

What Oceanfront Actually Requires Now

On the ocean side, flood-zone rules can shape what may be rebuilt.

That's not a reason to avoid oceanfront property. It's a reason to ask, before making an offer on anything older, exactly what the town would allow if the lot were rebuilt today, because the current structure and the eventual one may look nothing alike.

You're Buying the Lot, Not Just the House

Stone Harbor has been fully built out for decades. There's no open ground left, no new subdivision, no model home to tour. So when a lot changes hands, the pattern is almost always the same: whatever is standing on it comes down, and something custom goes up in its place. New construction here isn't a niche product. It's how a large share of the market actually moves.

That reshapes how a buyer should read a listing. On ground this expensive, the value sits in the lot far more than in the structure sitting on it. A dated house on the right block can be a better buy than a finished one a street back, because the real asset is the land underneath it and what the borough will let you build there. The gap between what newly built homes are trading for and what older stock on the same block commands is worth tracking closely. That gap is effectively what the market is charging to skip the rebuild yourself.

The Only Way Onto the Island Is Also Being Rebuilt

There's a second kind of construction that matters here too, and it isn't happening on any single lot. The 96th Street Bridge, the sole vehicle gateway between Stone Harbor and the mainland, is a nearly century-old drawbridge built in 1930 that uses a rare mechanical system called a Rall-type bascule, rare enough that the span is listed on the National Register of Historic Places. It's also been the source of real problems, including an emergency closure in 2016 after a crack was found in a main girder, and a 2023 county assessment that called its condition intolerable despite more than $2 million already spent on repairs.

Cape May County is now replacing it, at an estimated cost of $30 million. Mayor Tim Carney released an updated timeline this spring: construction outside the current bridge footprint is expected to begin this fall, with the existing span removed between September 2027 and spring 2028, a temporary span installed for the summer 2028 season to preserve traffic during the busiest months, and the new permanent span going in between fall 2028 and spring 2029. That's a later finish than the county's original 2028 target, and it's worth knowing before locking in a closing date or a renovation timeline tied to seasonal access.

For anyone buying with an eye toward rental income or a summer move-in, that multi-year construction window is a real planning variable, not a footnote.

Questions Worth Asking Before You Compare Prices

1. Which of the four submarkets is this listing actually in, interior, bayfront, oceanfront, or new construction?
2. If the structure came down tomorrow, what would the borough allow you to build in its place?
3. Is the price you're comparing it to a median sale, a median list, or an average estimated value, and from which month?
4. If it's bayfront, is the bulkhead the owner's responsibility or an association's?
5. If it's oceanfront, what flood-zone rules might apply if the lot is rebuilt?

A Couple of Direct Questions

Is now a bad time to buy because of the bridge construction? Not necessarily. The county has structured the work in phases specifically to preserve summer access, with a temporary span planned for the 2028 season. It's a factor to plan around, especially for anyone weighing seasonal rental income, not a reason to rule the island out.

Why do Redfin, Zillow, and other sites show such different prices for the same town? They're measuring different things. Median sale price, median list price, and an averaged value index will never match exactly, and on an island with as few monthly closings as Stone Harbor has, the gap between them can be wide in any given month.

Stone Harbor rewards buyers who ask which market they're actually in before they ask what things cost.
