The Former HGTV Dream Home on Plantation Key Is For Sale. About $1.2 Million of the Price Tag Isn't for the House.

A 3.2-acre bayfront compound at 139 Gimpy Gulch, tucked behind mature tropical landscaping next to the Founders Park lagoon on Plantation Key, is back on the market. The property started its public life in 2008 as an HGTV Dream Home. The winning family took the cash prize instead of the keys, and the house sold that same year for $2 million. It sold again in 2021 for $8 million. Now it's listed somewhere between $13.9 million and $14.9 million, depending on which outlet's most recent figure you trust, with two homes, a separate media house, more than 250 feet of sandy bayfront shoreline, a resort-style pool, and a new deep-water dock.

Buried in the listing is a detail that has nothing to do with square footage. The sale includes an adjacent vacant parcel, and the development rights attached to that parcel alone are being priced at roughly $1.2 million. Not the land under it. Not a structure on it. The right to build something there at all.

That single line item is the story worth understanding if you're looking at property on Plantation Key, because it points to a mechanism that changes how you should read every listing in this market, not just this one.

What Actually Changed Between 2021 and 2026

The compound grew a great deal between the original 2008 giveaway and today. What began as a single 3,500-square-foot showcase house has become a three-building compound with extensive outdoor entertaining space, a resort-style pool, and a new deep-water dock. Some of the jump from the $8 million sale in 2021 to the roughly $14 million asking price now likely reflects more of that same kind of physical build-out.

But not all of it. The listing itself makes clear that part of the current price reflects something that can't be photographed or walked through.

The gap between what a buyer gets in wood, concrete, and dock pilings and what they're actually paying for is the number worth sitting with.

Why a Right on Paper Now Has a Price Tag

The adjacent parcel's development rights carry standalone value because of one fact about Islamorada, which is that no building rights are left to issue for vacant land.

That fact describes supply. When a village stops issuing new building rights for vacant land, the rights that already exist attached to specific parcels become the only way to build something new. A vacant lot without a development right isn't really a buildable lot. It's dirt waiting on a legal instrument that the local government isn't creating any more of.

That's exactly why this listing bundles a vacant parcel with the main compound instead of selling it separately as raw acreage. The development right is the asset. The land is almost incidental to the price.

What This Means If You're Comparing Properties on Plantation Key

If you're pricing homes on Plantation Key against a median or against a neighboring canal, you're likely comparing structures, square footage, and shoreline frontage. That's the visible half of the equation. The other half, whether a parcel carries a transferable development right and whether that right is intact, recorded, and usable, doesn't show up in a walkthrough and rarely shows up in a casual comparison of asking prices.

Two homes on Plantation Key can look nearly identical from the water and carry very different real value once you account for what's actually attached to each deed. A compound with a spare, buildable parcel is not the same asset as one without it, even if the livable square footage is close to equal.

This is also why raw price-per-acre comparisons across the Upper Keys can mislead a buyer who hasn't priced in scarcity. A vacant parcel elsewhere might look cheaper per acre than the adjacent lot in this listing, but if it doesn't carry a usable development right, it may not be buildable at all in the current environment. The lower number isn't a better deal. It's a different kind of asset entirely.

What to Verify Before You Assume a Listing's Price Reflects Only What You Can See

• Whether any vacant portion of a parcel carries a recorded, transferable development right, and whether that right is documented separately from the general deed
• Whether the right has already been used elsewhere on the property, which would leave the vacant portion without one despite appearing buildable
• How the current allocation of building rights in Islamorada affects any future plans to add square footage, rebuild after storm damage, or subdivide

None of these questions get answered by a listing photo or a square-footage total. They get answered by pulling the actual permitting and development-rights history tied to the parcel, which is exactly the kind of due diligence that matters more on Plantation Key right now than it did five or ten years ago.

The Backstory Still Matters to the Number

There's a reason this compound can command a premium that a similarly sized property without the HGTV history might not. The original 2008 giveaway generated national attention, and the property has carried that name recognition through three ownership changes and a near sevenfold increase in value since the original sale. Brand recognition on a listing doesn't replace the underlying math of development rights, but it does explain why a buyer with the means to pay $14 million is looking at this particular address instead of a comparable one nearby.

Location plays its own role too. Sitting adjacent to Founders Park, with its tennis courts, sports fields, and waterfront recreation space, gives the compound a kind of everyday livability that a more isolated waterfront parcel wouldn't offer, even one with equivalent frontage.

The Number That Should Change How You Read the Next Listing

Strip away the HGTV history and the resort-style amenities, and the real lesson from this sale is narrow and useful. A development right on Plantation Key, and by extension across much of Islamorada, now has a market price independent of the land it sits on. That price is roughly $1.2 million in this transaction. It won't be identical on every parcel, but the principle holds everywhere the village has stopped issuing new rights.

If you're evaluating a property on Plantation Key and the seller hasn't told you whether the parcel carries an intact development right, that's the first question to ask, not the last one.
