How Pre-Construction Deposit Structures Work in Miami
Buyer's Guide · January 2026 · 5 min read
When you purchase a pre-construction condominium in Miami, you are not buying a finished product — you are buying a contract to receive a finished product, with your capital committed in installments over the construction period. Understanding how those installments are structured is one of the most important pieces of due diligence a buyer can do, and one of the most frequently misunderstood.
What a Deposit Structure Actually Is
A pre-construction deposit schedule is the sequence of payments you make between contract signing and closing. In Florida, pre-construction deposits are held in escrow by a licensed escrow agent and are regulated under the Florida Condominium Act — but the specific structure, timing, and percentages are negotiated between the developer and their sales team, and they vary significantly from project to project.
The deposit does not go toward your mortgage — it is applied to the purchase price at closing, reducing the amount you finance. Between signing and closing, your deposit sits in escrow, and the developer uses the aggregate escrow balance (across all buyers) as evidence of sales velocity and buyer commitment when negotiating construction financing with lenders.
The Standard Structures: What the Numbers Mean
The most common deposit structures in Miami pre-construction fall into a few recognizable patterns. A 10/10/10/10 structure requires four payments of 10% each, spaced across construction milestones — typically: signing, groundbreaking, top-off, and permit. By closing, you have placed 40% of the purchase price in escrow, with the balance financed or paid at closing. This structure is common on projects targeting a broad buyer pool, including international buyers who are financing at lower LTV ratios.
A 20/20/20/20 structure front-loads more capital — 80% of the purchase price in escrow by closing. This structure is typically associated with ultra-luxury or boutique projects where the developer is selecting for a higher-net-worth buyer profile and wants to minimize buyer default risk. It is also common on projects with strong developer brand equity, where the cachet of the address allows the developer to dictate more demanding terms.
Rule of thumb: the more aggressive the deposit schedule, the more confident (or selective) the developer. A developer requiring 50–60% in escrow before closing is either highly capitalized and not dependent on buyer deposits for construction financing, or is pre-selecting buyers who can carry the capital load.
Custom Milestone Schedules
Many of Miami's most prominent current projects use custom deposit schedules that are designed around the specific financing and construction timeline of that project. These schedules might look like: 20% at signing, 10% at groundbreaking, 10% at slab, 10% at top-off, with the balance at closing. Or they might front-load 30% at signing on the strength of a flagship brand.
Custom schedules require careful analysis. The key questions: What are the milestone definitions, and who determines whether a milestone has been reached? Is the deposit escrowed with a regulated Florida escrow agent? What are the buyer's remedies if construction is delayed past the contracted substantial completion date? These are the provisions where an experienced buyer's broker adds genuine value, because the answers are embedded in the purchase contract and are not always clearly disclosed in marketing materials.
What Deposit Structures Signal About Developer Confidence
The deposit structure is one of the best signals available to a sophisticated buyer about where a project sits in its financing and development lifecycle. A developer who is requiring 50%+ in escrow before closing is typically either: fully capitalized and using deposits as buyer-quality filter rather than construction capital, or has secured equity-level financing that doesn't depend on deposit flow. Both are positive signals for the buyer — they indicate a project with a lower probability of delay or cancellation.
Conversely, a developer offering unusually permissive deposit terms — low percentages, late milestone timing — may be doing so because they need the flexibility to attract a broader buyer pool or because their construction financing situation requires the perception of strong presales. This is not necessarily a red flag, but it warrants closer scrutiny of the developer's balance sheet, construction financing status, and track record on prior projects.
Florida Escrow Protections: What the Law Provides
Florida's Condominium Act provides meaningful buyer protections on pre-construction deposits. Deposits must be held in a Florida-licensed escrow account, and the developer cannot access the funds without meeting specific statutory conditions. If the developer fails to deliver the project within the committed timeframe and cannot secure buyer agreement to an extension, buyers are entitled to a full deposit refund including accrued interest.
There is a distinction, however, between statutory minimums and the specific protections negotiated in your individual purchase agreement. Sophisticated buyers push for enhanced escrow protections, specific default remedies, and clearly defined force majeure carve-outs. This is standard practice among the buyers in our network and should be part of any pre-construction contract review.
How to Evaluate a Deposit Structure Before You Sign
The first question is capital exposure: how much of your purchase price will be in escrow at any given point, and what is the opportunity cost of that capital? A buyer committing 40% of a $2 million purchase price — $800,000 in escrow — over a 36-month construction window should factor in the cost of that capital being illiquid, even if it is protected in escrow.
The second question is developer quality. The deposit schedule is only as meaningful as the developer's ability to deliver. Review the developer's prior projects, their current balance sheet, their construction lender relationships, and their track record on delivery timelines. A favorable deposit structure from an undercapitalized developer offers less protection than a demanding one from a developer with an impeccable delivery record.
The third question — often overlooked — is whether the deposit schedule matches your financing plan. If you are planning to finance at closing, your lender will have opinions about how much capital you have deployed in escrow and how that interacts with your loan qualification. This is a conversation to have with your mortgage advisor before contract, not after.
