Preconstruction — buying a unit before the building is finished, or even before construction starts — is one of the most popular ways international investors enter the Miami market. Properly understood, it offers a combination that is hard to find in a finished unit: launch pricing, payments spread over time, and appreciation potential while the project is being built. Poorly understood, it exposes buyers to risks worth looking at squarely before signing.
This guide explains how it works, what makes it attractive, and above all, what to check in a project before making the first deposit.
How the payment structure works
Unlike a traditional purchase, in preconstruction the price is paid in stages over the course of construction. A typical Miami structure spreads the outlay across successive deposits — for example, a portion at reservation, another at contract signing, and others at construction milestones — accumulating 40% to 50% before delivery, with the balance due at closing. Those deposits are generally held in an escrow account.
The practical consequence is that the investor does not need 100% of the entry capital upfront: they commit to the asset today, at today's price, and keep paying as the project advances, sometimes over two or three years.
Why it attracts investors
- Launch pricing: the first units usually go out at the project's lowest price; as sales progress, the developer raises the list price.
- Appreciation during construction: if the market and the project deliver, the unit can be worth more at handover than what was paid at the start.
- Staged payments: capital deploys over time, not all at once.
- New product: current amenities, construction warranties, and no renovation costs.
The risks, without varnish
Preconstruction is not risk-free. The main ones:
- Delays: delivery timelines slip; it pays to build in margin.
- Market cycle: if the market cools between signing and delivery, the expected appreciation may not materialize.
- The developer: the track record and financial strength of who is building carries the most weight; not every project delivers on time and as promised.
- Liquidity: exiting a contract before delivery is not always simple.
How to read a project before signing
Before the first deposit, it is worth reviewing:
- The developer's track record: what they have built before, how they delivered, and their reputation.
- Deposit protection: where the funds sit and under what conditions.
- The contract: timelines, penalties, assignment conditions, and what happens if there are delays.
- The specific unit: line, view, floor and projected common charges; not every unit in the same building performs the same.
- The neighborhood: the project delivers into a context, and location matters as much as the tower. It helps to compare options, as in Brickell versus Edgewater.
Miami today has a broad pipeline of preconstruction and new developments, from bayfront towers to luxury brands with hotel-style service. The difference between a good and a bad purchase is rarely in the brochure — it is in the contract's details and the judgment used to choose the project.
Frequently asked questions
What does it mean to buy preconstruction?
It means buying a unit before the building is finished, sometimes before construction even starts, paying the price in stages over the course of construction.
How much do you have to pay upfront?
It varies by project, but a typical Miami structure accumulates 40% to 50% of the price in staged deposits before delivery, with the balance due at closing. Deposits are usually held in an escrow account.
Is it riskier than buying a finished unit?
It carries different risks: delivery delays, the market cycle, and the developer's track record. In exchange, it offers launch pricing and staged payments. The key is analyzing the project and the contract before you sign.
Can I sell before delivery?
Sometimes, through an assignment of contract, but it is not always simple and not every project allows it. It is worth reviewing that condition in the contract from the start.
