Say you're watching a three-bedroom cottage a few blocks off Reid Avenue, listed at $329,000. You've done your homework. Redfin tells you Port St. Joe homes are taking 118 days to sell right now, up from 90 days a year ago, and that the market scores a 14 out of 100 on competitiveness, about as far from a bidding war as a number gets. So you write an offer with a long inspection period and a number well under asking, figuring you have room. Then the seller takes a full-price offer from someone else within the week.
Nothing about the Redfin number was wrong. It just wasn't describing the house you were bidding on.
What the portals are actually measuring
Pull up Port St. Joe on any major site right now and you'll see a market that looks tired. Redfin's most recent read puts the average sale price at $475,000, up 27.5 percent year over year, while the median sale price over the three months ending June 2026 sits at $440,000, up a more modest 2.3 percent. Homes are taking 118 days to sell on average, against 90 days the year before, and Redfin's compete score of 14 signals almost no bidding pressure. Zillow's home value index, updated through the end of July 2026, shows the average home value at $469,759, down 3.4 percent over the past year, with homes going to pending in around 64 days.
Notice the gap between those two portals before you even get to the local data. Redfin is tracking time to close a sale. Zillow is tracking time to go pending. Different clocks, different answers, both accurate for what they measure. That gap is the first hint that a single number can't carry the weight of describing an entire town's market.
The bigger gap shows up when you compare either portal to what's actually clearing on the ground week to week.
The tighter number underneath
A local weekly closing report that tracks Forgotten Coast sales property by property told a different story for the week of June 15 through 21, 2026. Coast-wide, inventory stood at 620 active residential listings with 8.9 months of supply, a buyer's market by any standard measure. But Port St. Joe itself was running well below that average. With 100 active listings and 3 under contract, the projected sales pace worked out to roughly 13 closings a month, which puts months of supply at 7.7, the tightest reading anywhere on the coast that week.
The three homes that closed in Port St. Joe that week ranged from $289,900 to $349,900, averaging $319,900. That's not a market sitting on its hands for 118 days. That's a segment of Port St. Joe clearing on a pace closer to two months of supply than eight.
So which is it? Both, at the same time, because they're describing different slices of the same zip code.
Two products wearing one town name
Port St. Joe's housing stock splits cleanly into two categories that don't behave the same way, and blending them into a single town average is what produces the confusing portal numbers.
On one side sits the older housing stock: bayfront cottages, historic downtown homes, and waterfront lots that trade in the low $300,000s. This is the tier delivering those fast, attainable closings the weekly reports keep flagging.
On the other side sits WindMark Beach, the master-planned community between Port St. Joe and Mexico Beach built out by D.R. Horton on land developed by The St. Joe Company. WindMark's newer construction runs in two distinct product lines. The Tradition Series is the community's lower-priced entry, built with Hardie siding and vinyl plank flooring aimed at buyers who want new construction without the top-end finish package. The Emerald Series is the upgraded tier, and as of a June 2026 update to WindMark's new-home listings, those floor plans, named Lily, Jubilee, Islamorada, and Brayden among others, run from $624,900 to $749,900 for homes starting around 2,063 square feet. WindMark's Village Center adds its own texture to the community, anchored by a restaurant called The View and a handful of smaller spots including a pizza place and a casual breakfast counter, all connected to the beach by a boardwalk network rather than a street grid.
New construction at that price point tends to sit longer. It's a bigger financial commitment, it competes with a smaller pool of buyers who can absorb a $700,000 mortgage on a second home, and builders are often willing to hold a price rather than discount into a slow month. Fold enough of that inventory into a town-wide average alongside $320,000 cottages that turn over in weeks, and you get exactly what the portals are showing: a rising average price, a stretched-out days-on-market figure, and a competitiveness score that reads as sleepy.
The entry tier isn't sleepy. It's the reason the town-wide days-on-market number keeps climbing even while the price band doing most of Port St. Joe's actual weekly closings moves at a pace that would qualify as a seller's market almost anywhere else on the coast.
Why this matters more than the median
If you're comparing Forgotten Coast towns from a spreadsheet built off portal exports, Port St. Joe reads as the softest option: rising days on market, a weak compete score, values technically down year over year on the Zillow measure. That comparison isn't dishonest. It's just built on a number that averages together two buyer pools who never actually compete against each other for the same house.
A buyer shopping WindMark's Emerald Series should expect something closer to the portal picture: more negotiating room, more time to think, builder incentives worth asking about. A buyer shopping the $300,000 to $350,000 tier downtown or along the bay should expect something closer to the weekly closing data: multiple comparable sales clearing inside a couple of months, less patience from sellers, and less room for a lowball opening number.
Writing an offer as though the whole town operates on the same clock is where the friction shows up. The buyer in the opening scenario wasn't wrong to research the market. He was wrong to apply a town-wide average to a specific price band that's moving at roughly a third of that pace.
Before you write that offer
A few questions worth answering before you put a number on paper in either tier:
- What price band is the house actually in, and what have comparable closings in that specific band done in the last 30 to 60 days, not the last 12 months?
- Is the seller motivated by a builder's incentive structure and inventory targets, or by a personal timeline that makes speed the priority?
- What does the seller actually net after commission, title costs, and Florida's documentary stamp tax on the deed, which runs $0.70 per $100 of sale price? Knowing that number tells you how much room a seller genuinely has before a lower offer stops making sense to them.
None of this requires abandoning the portals. It requires treating them as one data point instead of the whole picture, and pairing them with a look at what's actually closing in your specific price band that week, not that year.
The takeaway
Port St. Joe's 118-day average and its 7.7-month entry-tier supply are both true at the same time, because they're measuring two different housing products that happen to share a zip code. A buyer working the sub-$350,000 tier who assumes they have the leverage the town-wide numbers imply is working from the wrong data set. A buyer eyeing WindMark's newer construction who panics at a tight-sounding coast-wide report is doing the same thing in reverse.
If you're trying to figure out which version of Port St. Joe your target house actually belongs to, that's the exact kind of question a local read answers faster than a portal export ever will.
