The Complete Guide to Buying Pre-Construction in Miami: Deposits, Timelines & Risks

Buying a pre-construction condominium in Miami is fundamentally different from buying a resale property — and different in important ways from pre-construction purchases in other markets. The legal framework, deposit structures, developer obligations, and risk profile all require specific knowledge. This guide covers what every buyer needs to understand before signing a Miami pre-construction purchase agreement.

The Purchase Agreement: What You’re Actually Signing

A Miami pre-construction purchase agreement is a contract to purchase a unit that does not yet exist in its final form. You are buying based on a floor plan, a rendering, and a set of specifications — all of which are subject to material changes by the developer under Florida law within defined limits. Key provisions to understand and negotiate include:

• The Florida Rescission Period: Florida law provides a 15-day right of rescission for pre-construction condo purchases. Within 15 days of receiving the offering documents (disclosure statement), you can cancel and receive a full refund. This is your most important legal protection — use it to conduct thorough due diligence.
• Material Specification Changes: Developers typically reserve the right to make changes to unit specifications, floor plans, and building amenities. The key question is: what constitutes a “material” change that triggers your right to cancel? Your attorney should review this language carefully.
• Delivery Date and Termination Rights: What happens if the project is significantly delayed? What are your remedies? Florida law provides some baseline protections, but the purchase agreement specifics matter enormously.

The Deposit Structure

Miami pre-construction projects typically require deposits ranging from 20% to 50% of the purchase price, paid in staged installments during the construction period. A typical structure for a $900,000 unit might look like:

• 10% at contract execution ($90,000)
• 10% at groundbreaking ($90,000)
• 10% at 50% construction completion ($90,000)
• 10% at top-off ($90,000)
• Balance at closing

Your deposits must be held in escrow — typically in a Florida-licensed escrow account — and cannot be used by the developer for construction without specific conditions being met. Verify the escrow arrangement and the name of the escrow agent before signing.

Developer Due Diligence: The Most Critical Step

The single most important factor in any pre-construction purchase is developer credibility. Questions to research and verify:

• Has this developer completed previous projects on time and at spec?
• Is construction financing secured, or is the project dependent on presales to fund construction?
• What is the developer’s financial strength and track record through previous real estate cycles?
• Are there any pending litigation or regulatory issues?

We conduct this due diligence on every project we recommend to our clients. We have declined to present projects to our buyers that were receiving significant industry marketing precisely because the developer did not meet our credibility standards.

The Assignment Clause: Your Liquidity Option

Before signing any pre-construction purchase agreement, understand your assignment rights. An assignment allows you to sell your purchase contract to another buyer before closing — realizing appreciation without taking title. Some Miami developers restrict assignments entirely; others permit them with consent and a fee. For investment-motivated buyers, a project with flexible assignment rights is significantly more valuable than one without.

Timeline Expectations

Miami pre-construction projects typically take 3–5 years from sales launch to occupancy. Plan for this timeline in your financial modeling. Your deposits are effectively illiquid during construction — you are receiving no income and paying no mortgage, but your capital is deployed. The benefit is that you are locking today’s price for a future asset, in a market where prices have consistently trended higher over delivery cycles.
