Pull up Port Royal across several market sources this week and you will find conflicting signals about which direction the market is moving. One shows the median climbing. Another shows it falling by double digits. A third estimates average home value, while listing prices are much higher than the reported closed-sale prices. None of them are wrong. They are measuring different things, in a neighborhood small enough that a handful of sales is all it takes to move the number.
That instability is not a data glitch. It is the defining fact of shopping in Port Royal right now, and it changes how a serious buyer should read every number this neighborhood produces.
Different Sources, One Neighborhood, Different Answers
Here is what shows up if you check the major portals in August 2026.
| Source | What it measures | Figure | Time window | Year-over-year |
|---|---|---|---|---|
| Redfin | Median closed sale price | $17.0 million | 3 months ending June 2026 | up 3.6% |
| Homes.com | Median closed sale price | $15.5 million | Trailing 12 months, as tracked this year | down 14% |
| Zillow | Estimated average home value | $14.75 million | As of June 2026 | up 5.9% |
| Realtor.com (via local market reporting) | Median listing price | $27.9 million | March 2026 | not applicable, asking price |
| Redfin luxury inventory | Median listing price, active homes | $28 million | August 2026 | not applicable, asking price |
Look closely and the disagreement is not just noise. Redfin and Homes.com are both reporting a median closed sale price, both current for mid-2026, and they disagree on direction entirely. One says the market is up. The other says it is down 14%. Zillow is measuring something different again, an automated estimate of average value rather than an actual transaction price. Realtor.com's number and Redfin's own live inventory figure are asking prices on homes that have not sold yet, sitting well above the closed-sale medians.
You could reconcile Zillow against a listing price, or a listing price against a closed sale, and explain away part of the gap through methodology. Redfin and Homes.com are measuring the same thing over different windows, which can help explain why they disagree on direction. The specific sales included matter, too.
Why a Median Breaks Down in a 9- or 10-Home Market
Redfin's own data shows the mechanism. Port Royal closed 10 home sales in June 2026, up from 9 the prior June. That is the entire monthly sample. In a market that size, the median is not describing a trend line. It is describing the specific properties that happened to close in the window a given report is using.
This year's transaction activity shows exactly how much weight a single sale can carry. Reporting earlier in 2026 documented an $85 million waterfront sale, a $225 million transaction covering three contiguous Gordon Drive parcels sold together, and a newly built estate that closed at $24.95 million. In April 2026, the Business Observer reported a separate Port Royal sale at $40 million, noting it was the latest residential property in the city to clear the $30 million mark. Any one of those sales, if it falls inside a three-month or twelve-month window, may influence that window's median, depending on the other sales included.
That is why Redfin's three-month window ending June 2026 can show a median up 3.6% while Homes.com's trailing twelve months, capturing a different set of closings, shows a median down 14%. Both are technically accurate. Neither is describing what Port Royal home values are actually doing, because at this sample size there is no such thing as a stable "what Port Royal is doing." There is only which specific houses sold.
For a buyer, the practical upshot is this: a headline median for Port Royal tells you almost nothing about what a specific listing should cost. It tells you which trophy estates happened to close recently.
What Actually Tells You Something
If the neighborhood median is not a useful yardstick, the alternative is to look at the same handful of variables that separate one Port Royal listing from another, regardless of what the aggregate is doing that quarter.
- Elevation certificate and its relation to Base Flood Elevation. Port Royal sits in an AE flood zone, according to Augurisk, and the relationship between a structure's actual elevation and its Base Flood Elevation drives both insurance pricing and long-term insurability. A newly constructed home elevated well above the minimum is a fundamentally different asset than an older home sitting below that line, even on the same street.
- Construction or renovation date. Homes built or substantially rebuilt to current wind and flood code carry a different cost and risk profile than homes that predate those standards, independent of finish quality.
- A bindable insurance quote, not an estimate, before you write an offer. Two homes in the same flood zone can price very differently once elevation, construction, and claims history are factored in.
- Comps from the same street or cove, not the neighborhood at large. Gordon Drive, Admiralty Bay, and the interior canals each carry their own logic around exposure, dock access, and buildability. A neighborhood-wide median blends all of them into a number that fits none of them.
None of this requires waiting for a cleaner median. It requires treating the median as background noise and pricing the specific house instead.
The Clubhouse
Capital is still moving into Port Royal regardless of what the aggregate numbers say this quarter, and the clearest evidence of that is happening at the club itself. Port Royal Club is completing a clubhouse rebuild reported at roughly $100 million, with completion targeted for summer 2026. That kind of reinvestment tends to track long-term confidence in an address more reliably than a monthly median based on a small number of sales.
What This Means for Your Search
A Port Royal listing priced against "the neighborhood median" is being priced against a number that changes depending on which website you check and which properties happened to close in the reporting window. That is not a reason to distrust the market. It is a reason to stop asking what Port Royal homes are doing in aggregate and start asking what a specific house, on a specific street, with a specific elevation certificate, is actually worth.
If you are comparing a Port Royal property against something in a neighboring waterfront enclave, the same caution applies in reverse. A market this thin does not average out the way a 500-home subdivision does. Every comp has to be read for what it actually was, not what the published median implies.
A Few Questions Worth Asking Before You Look Further
Why do different websites report different prices for the same neighborhood? Because they are often measuring different things over different windows. A median closed sale price over three months, a median closed sale price over twelve months, an automated value estimate, and a median asking price on active listings are four different metrics that will naturally diverge, and in a market with only nine or ten monthly closings, that divergence can be dramatic.
Does a flood zone designation limit a Port Royal home's value? Not by itself. Being in an AE zone does not automatically depress value in a neighborhood where proximity to the Gulf and Naples Bay is the entire premise. What matters more is the specific home's elevation relative to Base Flood Elevation, its construction date, and whether it has documentation ready for an insurance quote.
