Beach House 8

What is actually inside the building

The Miami-Dade County Property Appraiser holds seven folios at 3651 Collins Avenue, and every one is a residence. The declaration’s common-element shares close, so this is the entire condominium.

Seven homes. Almost all of them are the same home: five four-bedrooms of 3,403, 3,405, 3,410, 3,413 and 3,414 square feet — eleven square feet separates the smallest from the largest. The other two are a 4,642 square foot five-bedroom and a 6,678 square foot seven-bedroom.

That uniformity is what makes this page unusual. In most buildings I have to warn that comparing sales across different-sized homes is unreliable. Here, five of the seven are effectively the same apartment, so the county record can be read almost as a controlled experiment.

The 2026 assessed values run $5,462,500 to $13,029,500, with a median of $5,954,100.

Five near-identical homes, five different prices

The building sold in 2016, and the original closings are the first thing worth seeing. All five of the ~3,410 square foot four-bedrooms traded between 23 May and 6 July 2016 — a six-week window:

Homes within eleven square feet of one another, sold within six weeks of one another, at prices ranging from $5,625,000 to $7,500,000 — a spread of 33.3%.

The county record shows what was paid, not why, so I cannot tell you whether that reflects floor, exposure, finish level, or simply what each buyer agreed to. What it does establish is that two buyers paid $1,875,000 more than two others for essentially the same apartment in the same summer — and, as the next section shows, that starting price determined almost everything about how they did afterwards.

What happened to the people who bought in 2016

Four of the seven homes have since recorded a second qualified sale. Both legs of each of these is a qualified, arm’s-length transaction above a nominal amount — nominal transfers and one sale the county declines to qualify are excluded rather than filtered by price.

The pattern is almost perfectly ordered by what each buyer paid at the start. The two who bought at $5,625,000 and $5,760,800 are up 28.0% and 32.8%. The two who paid $7,500,000 are down 1.3% and 20.0%.

The $7,500,000 buyer of June 2016 had an intermediate step worth noting: the home resold at $6,581,400 in August 2017 — down 12.2% in fourteen months — before the 2021 sale at $6,000,000.

Every one of these homes is within eleven square feet of every other. There is no size explanation, no floorplan explanation and no market-timing explanation that separates them, because they were all bought in the same six weeks. What separated the outcomes was the entry price.

I want to state the limit honestly: this is four transactions in a seven-home building, and the county record does not tell you the condition of any home at either sale or what each deed included. But four of seven is a majority of the building, the homes really are alike, and the ordering is hard to dismiss.

The highest price ever recorded here is $14,000,000, on 27 May 2016, for the 4,642 square foot five-bedroom — $3,016 per square foot. A later transaction on that home is recorded at a higher figure but the county does not flag it as a qualified sale, so it is excluded from every comparison on this page. Nothing qualified since 2016 has approached $3,016 per square foot; the most recent sale in the building, in May 2026, cleared at $2,241.

Note also what is absent: no qualified sales at all in 2023 or 2024. The building produced one in 2025 and one in 2026.

Who this building suits

It suits a buyer who wants a 3,400 square foot oceanfront four-bedroom in a building with six neighbours. That is a genuinely rare product, and the near-identical layouts mean you can price a purchase against four recorded round trips of the same apartment — which is more direct evidence than most buyers of a $7,000,000 home ever get.

The lesson the record teaches is about entry price, and it is unusually clear. In this building, what you pay going in has determined the outcome more than how long you held: a buyer at $5.7 million made 32.8% over ten years while a buyer at $7.5 million lost 20.0% over five. Negotiate hard, and treat the 2016 launch prices as evidence rather than as a benchmark.

It suits anyone needing liquidity badly. Two qualified sales in four years, none at all in 2023 or 2024, in a seven-home building. If you need to sell on a timetable, this is close to no market — and if a second owner lists at the same time, you are competing directly with them.

Weigh the association carefully. Seven owners share every cost here. A special assessment, an insurance renewal or a structural reserve requirement divides seven ways, and one owner falling behind is over fourteen per cent of the budget. Ask for the reserve study and the last three years of accounts before anything else.

If you are selling here, your comparables are the November 2025 sale at $7,400,000 and the May 2026 sale at $7,650,000 — both near-identical to most of the building, and both usable. Price against those rather than against 2016. Ask me before you set a number.
