Old Naples Ran Out of Houses. The Average Price Fell Anyway.

How does a neighborhood run out of inventory and get cheaper at the same time?

That is what happened in Old Naples' luxury single-family market in the first quarter of 2026. Active listings priced at $1 million and above fell 34.6 percent year over year, down to just 70 homes, according to a 12-month rolling analysis of InfoSparks data through the Southwest Florida MLS. Months of supply collapsed 59.2 percent to 13.8 months. Pending sales jumped 59 percent to 62 contracts, and closed sales rose 60.5 percent to 61 transactions. By any normal reading, that combination, less to buy and more people buying it, should push prices up.

Instead, the average single-family sale price softened 9.7 percent to $6,494,221, and price per square foot fell 28.4 percent to $1,743.

If you're comparing Old Naples against Port Royal or Aqualane Shores using whatever number a search result handed you, this is worth slowing down for. The neighborhood didn't get cheaper. The math got more complicated, and the complication is the useful part.

Three Numbers, One Neighborhood

Part of the confusion is that "Old Naples home prices" can mean at least three different things depending on which data set you're reading and which month it was pulled.

Each of these is accurate. None of them is describing the same slice of the market. The first blends a one-bedroom condo near Third Street South with a Gulf-front estate, which is why its per-square-foot number sits at $930, less than half the $1,743 luxury single-family figure directly above it. The third is scoped to a wider beach corridor that includes Old Naples but isn't limited to it.

There's also a statistical distinction hiding in plain sight: the March figure is an average, the arithmetic mean, which a single outlier sale can drag hard in either direction. The July figure is a median, the middle value in the stack, which moves less because of any one closing. When a headline says Old Naples prices jumped or fell, the first question worth asking is which of the two it used.

What Actually Happened Between March and July

The mechanism behind the swing is a supply hangover clearing out.

A year before the March 2026 numbers, in February 2025, active $1 million-plus listings in Old Naples had spiked to 111 homes, a level the market itself has described as an oversupply. That glut sat on the market through most of 2025. As buyers worked through it in late 2025 and early 2026, the closings pulling down the average weren't distressed sales or falling values. They were simply a backlog of previously-listed homes finally transacting, and the mix of what closed in any given month skewed toward whatever had been sitting longest, not necessarily the top of the price ladder.

By the time that backlog thinned out, the sales mix shifted back toward the top. That's the story the July 2026 NABOR Market Report tells for the broader Naples Beach corridor, released August 21, 2026: single-family closed sales up 37.5 percent year over year, with the median closed price climbing 31.6 percent to $2.5 million, up from $1.9 million in July 2025. Every one of the ten highest-priced residential sales in Naples that month landed in Port Royal, Old Naples, or Aqualane Shores. The single highest was a $41.18 million waterfront estate in Port Royal.

Read the two data points side by side and the picture stops looking like a contradiction. It looks like a market working through an inventory backlog first, then reasserting itself at the top once that backlog cleared.

A shrinking supply and a falling average aren't opposites. In a market this thin, they can be the same event described from two different months.

The Sale That Explains the Sample Size Problem

There's a second reason Old Naples numbers swing hard: the sample size is small enough that one closing can move the headline by itself.

A Gulf-front home at 26 2nd Avenue South closed in 2026 for $27 million, the highest price paid for an existing residence in Old Naples this year. The home, designed by Humphrey-Rosal Architects and built by D. Garrett Construction, was completed in 2025 on a 0.52-acre homesite with 120 feet of direct Gulf frontage, delivered as a decorator-ready residence with full concrete construction on every level. A Gulf-front triple lot traded for more earlier in the year, but that transaction was raw land, not a finished home, so the $27 million figure stands as the top residential comp.

When a neighborhood is only producing 60 or 70 closings a year in its luxury single-family tier, one $27 million sale, or one $41.18 million sale in neighboring Port Royal, carries enough weight to shift the average by itself. That's a different situation than a suburban subdivision closing 60 homes a month, where any single sale barely registers. It's also why the average and the median tell such different stories here: the average absorbs the outlier directly, while the median mostly shrugs it off.

What This Means If You're Pricing a Listing or Sizing Up an Offer

The practical takeaway isn't that Old Naples numbers are unreliable. It's that the headline figure answers a different question than the one most buyers and sellers are actually asking. A few things worth checking before you anchor to any single number:

• Months of supply within your specific price tier, not the neighborhood-wide figure. Thirteen months of supply in the $1M+ single-family segment tells you something very different than a blended figure across condos and cottages.
• The pending-to-active ratio for comparable homes, since a high ratio in a thin market can mean real absorption even while the average price is still catching up.
• Price per square foot within your lot type, since a Gulf-frontage estate and an interior-lot cottage a few blocks apart can carry per-square-foot values that differ by a factor of two or more.
• Whether the recent comps you're being shown include an outlier closing, like a $27 million or $41 million sale, that's doing more work in the average than it should for your actual home.

There's also a demand-side detail worth watching if you're shopping the corridor rather than selling into it. As of an April 2026 report, Naples Beach Club, the new construction development along the beachfront, had roughly three of its 58 residences left unsold, with first closings slated to begin that May. A development that close to sellout pushes part of the buyer pool that would otherwise be shopping new construction back into resale, which is one more reason the corridor's absorption accelerated through the summer.

A Few Questions Worth Asking Before You Act

Does the early-2026 price softening mean Old Naples home values actually fell? Not in the way that phrase usually implies. The average dropped because the mix of what closed shifted toward the middle of a glutted luxury tier as that glut cleared, not because comparable homes were selling for less. The July reversal at the corridor level is consistent with that reading.

Is the $27 million Gulf-front sale a fair comp for a smaller lot? No. That sale carries 120 feet of direct Gulf frontage on a half-acre homesite with new construction, a combination that's rare enough in Old Naples to set its own price tier. It's useful for understanding what moves the average, less useful as a direct comp for an interior lot or an older cottage.

What should I actually watch heading into fall? Months of supply in your specific price band, the pending-to-active ratio for genuinely comparable homes, and whether recent closings near your price point include an outlier that's skewing the average in either direction.

Old Naples doesn't move like a typical market, and treating its headline number like a typical market's median is how both buyers and sellers end up mispricing a decision.
