$10 MILLION +

There is a precise answer to where Miami’s ultra-luxury market begins, and for the first half of 2026 it is this: $10.0 million for a condominium and $15.0 million for a single-family home. Those are the top 1% thresholds for Miami-Dade — and both moved sharply in twelve months. At South Florida level the single-family ultra-luxury line rose from $7.8 million in 2025 to $10.7 million. A 37% move in the definition of the top of the market, in one year.

Why there are no medians on this page

Above $10 million, Miami’s trophy enclaves individually transact in the single digits each year. A median calculated on eight sales is not a statistic; it is an anecdote with a decimal point. Publishing one implies a precision that the underlying data cannot support, and it is the most common way ultra-luxury marketing misleads people who ought to know better.

What is worth publishing is the direction and the shape of the market. Miami-Dade closed $2.4 billion of dollar volume in June 2026, up 36.39% year over year, on transaction growth of 14.3%. Volume is growing at more than twice the rate of activity. That is a mix shift, and this band is where the mix shifted to.

The threshold moved faster than the assets did

Hold the two years side by side. At South Florida level the top 1% single-family threshold went from $7.8 million to $10.7 million, and the condominium equivalent from $5.4 million to $6.0 million. In Miami-Dade specifically the top 1% now begins at $15.0 million for houses and $10.0 million for condominiums.

Two things do that. New supply at extreme price points enters the sample and drags the percentile upward, and genuine repricing at the top. Both are happening in Miami simultaneously, and disentangling them is the single most useful piece of analysis available to a buyer at this level — because one of them is durable and the other is a composition effect that reverses when the delivery pipeline thins.

The practical consequence: comparables at this level are not a search result. They are a hand-assembled set, and the wrong set produces confident nonsense. An address one gate outside a named enclave, a sale that included furniture and a boat slip, an assemblage priced as a single trade — each of these regularly enters comparable sets where it does not belong.

What actually determines value up here

Land, not improvements. On the water, an increasing share of trades at this level are teardowns and assemblages, where the house is a rounding error and the price is a function of frontage, lot size, and what can be built. New construction on the best waterfront clears multiples of what older stock does per square foot — which means an existing house can be simultaneously beautiful and irrelevant to the price.

Dockage, specifically. Channel depth, bridge clearance and the number of turns to open bay separate otherwise similar addresses by a wide margin. Among Miami’s gated waterfront enclaves the per-square-foot spread runs well over 2x across communities that sit within a few miles of each other, and dockage explains more of it than prestige does.

Governance. Several of the enclaves at this level require club membership as a precondition of purchase — written application, financial disclosure, letters of recommendation from existing members, an interview, and a board that may reject an applicant for cause. Approval is often final only on taking title. Where an inner enclave sits inside a larger community, both fee structures apply. These are not formalities and they are not negotiable, and they belong in your timeline from the first conversation, not the week before closing.

The one condominium question that still matters at $10 million

Financing is generally irrelevant to your purchase and entirely relevant to your building. Florida Statute 553.899 applies to every condominium and cooperative building three habitable stories or more: milestone inspection by 31 December of the year it reaches 30 years of age, then every ten years, with local enforcement agencies empowered to require the first at 25 years. And the agency standards your future buyer will face are tightening — Limited Review retired 3 August 2026, a $50,000 per-unit master deductible cap since 1 July 2026, and minimum reserves rising to 15% of annual budgeted assessment income on 4 January 2027.

At $10 million and above the assessment exposure that follows an adverse milestone finding is not a rounding error either. It is worth knowing before, rather than after.

How this market actually works

A meaningful share of trades at this level never appear as listings. They are assembled — between brokers who know which owner is quietly willing, at a price neither party wants published. If you are buying above $10 million in Miami and you are working exclusively from what is publicly for sale, you are seeing a fraction of the market, and usually the part that has already been passed over.

Tell me what you are looking for and I will tell you honestly whether it exists, what it should trade at, and whether the comparable set anyone has shown you is the right one.
