Four ways to buy separateness in Miami, and they cost wildly different amounts of daily friction. The desk at Miami Dossier ranks them by what they actually keep out.
Written by the desk at Miami Dossier for readers whose first requirement is privacy rather than a view or a brand. All comparisons.
Buyers who put privacy first usually start by naming Fisher Island, because it is the most extreme answer. It is rarely the correct one. Privacy in Miami is bought in degrees, and the useful question is what you are trying to keep out, because the cheapest solution that achieves it is almost always better than the most complete one.
Fisher Island removes everyone. No bridge, ferry or boat access only, so nobody is there who does not live there, work there or was invited. This is the only position in Miami that achieves a total filter.
Brickell Key removes passing traffic and casual foot traffic. One bridge, one guarded entrance, a loop road, no through route to anywhere. It does not filter out the public entirely and it does not need to.
Bal Harbour removes traffic and noise through governance rather than geography. A village of about a third of a square mile with its own police force and no route through it. The Shops bring people into the village daily, which is the trade.
Key Biscayne removes urban density. A causeway, a village government, a community of families, and a great deal of open space. It filters by distance and by character rather than by a gate.
Fisher Island costs a boat trip, permanently. A forgotten item is a round trip. Contractors cost more and schedule harder. A late dinner on the mainland ends on the water. Teenagers find it constraining and that is the most common regret the desk at Miami Dossier hears about the island.
Brickell Key costs a bridge and a few minutes. That is close to nothing, which is why it is the most under-considered answer on this page.
Bal Harbour costs almost nothing in friction and costs choice instead: one building in tier and a village that is effectively built out.
Key Biscayne costs a causeway and a commute, and there is nothing in this tier there, so the product is houses and established condominiums rather than new construction.
For the large majority of buyers who arrive asking about Fisher Island, Brickell Key is the better answer. It delivers most of the filtering effect at a fraction of the daily cost, and buyers who have spent a year on the ferry frequently arrive at the same conclusion the long way round.
The exception is real. If your requirement is that nobody uninvited can physically reach you, only Fisher Island does that, and no bridge-accessible alternative substitutes. That requirement is rarer than the number of people who state it.
Your situation is specific. Tell the desk in one message and we will say what applies to you, what does not, and who to speak with.

What is in tier at Miami Dossier in each, and what each position genuinely delivers.
If the problem is passing traffic, noise and a city that never stops, Brickell Key solves it for the price of a bridge and it is the most under-considered answer in Miami.
If the problem is that you want the ocean and a community rather than a compound, Bal Harbour solves it through governance and Rivage is the one building in tier there.
If the problem is that nobody uninvited may physically reach you, only Fisher Island solves it, and you should spend a weekend there before you agree to the ferry for the next twenty years.
Most of the people who bring this comparison to the desk at Miami Dossier are not only choosing between buildings. They are moving to Miami from New York, California, London, Bogotá, Mexico City or São Paulo, or adding a Miami position to a portfolio held elsewhere, and the building question sits inside a larger one: how to buy new construction here, how to hold it, and what changes when you do.
The desk keeps short notes on the parts that come up every week: how buying preconstruction in Miami actually works, what a normal deposit schedule looks like, whether you need to be in Miami to buy, whether a foreign buyer can get a mortgage, what taxes a foreign buyer pays on a Miami condo, what happens if a developer delivers late, and the Florida state income tax question. For buyers arriving from a specific market there are notes for Bogotá, Mexico City and London.
Read the ones that apply, then bring the rest to the desk at Miami Dossier. It usually takes one conversation to see which of these fits, or whether neither does.
This page is general information for people considering Miami, written by a real estate desk, not by a law or accounting firm. Nothing here is legal, tax, immigration or investment advice, and it is not a substitute for advice on your own circumstances. Rules change, treaties differ by country, and the right answer for one family is the wrong answer for another.
Figures and building details are compiled from developer documents held by the desk at Miami Dossier and from public filings. They are approximate, subject to change, and anything material should be confirmed against the current developer release before you rely on it. Where the desk at Miami Dossier does not know something, the page says so.
Speak with your own attorney and CPA before you commit to anything. If you do not have one who works with international buyers in Florida, the desk is glad to recommend an attorney, a CPA or an adviser suited to your situation, and to sit in the first conversation so that nothing is lost in translation.
Structure, financing, currency, timing, the right building and the right line: the desk works through these questions with international buyers every week. What this page cannot do is know your position. Tell us the shape of it and we will say plainly which of these fits, which does not, and what we would want to see before anyone commits.
