How to Buy or Sell a Miami Luxury Condo Assignment (2026)

Miami's pre-construction condo market moves fast, and sometimes life moves even faster. I work with buyers and sellers every year who signed a contract on a new condo tower, watched the building rise, and then needed to exit before the closing date arrived. Maybe a job relocated them. Maybe the investment thesis changed. Maybe they simply found a better opportunity. Whatever the reason, an assignment sale is often the cleanest path forward, and it is one of the least understood transactions in Miami real estate.

An assignment sale happens when the original buyer of a pre-construction unit transfers their purchase contract to a new buyer before the developer closes on the unit. The original buyer is called the assignor. The new buyer is called the assignee. The developer stays in place. The assignee steps into the shoes of the assignor, takes on all the rights and obligations in that original contract, and eventually closes directly with the developer. No deed changes hands at assignment. The money flows at the final closing.

In my experience, assignment transactions require more due diligence than a standard resale purchase, more negotiation skill than most buyers expect, and a careful read of the original purchase contract before anyone signs anything. I have guided clients through assignments at Brickell Flatiron, Aston Martin Residences, Una Residences, and several Sunny Isles towers. This guide covers what I tell every client before we start.

What Makes Miami a Hotbed for Assignment Sales

Miami towers typically take three to five years from groundbreaking to closing. A buyer who signed a contract in 2021 for a Brickell or Edgewater tower may not close until 2025 or 2026. That is a long time for circumstances to stay static. International buyers, who make up a significant share of pre-construction purchasers here, face currency fluctuations, visa changes, and shifting investment priorities across that window. Latin American buyers from Venezuela, Colombia, Brazil, and Argentina often buy in pre-construction precisely because the deposit structure lets them stage capital over time, but those same market conditions can reverse.

Beyond personal circumstances, there is also a pure investment play. A buyer who locked in a unit at $900 per square foot in 2022 may be looking at a comparable delivered unit selling for $1,300 per square foot by the time the building tops off. Assigning that contract for a profit, sometimes called flipping a paper, is entirely legal in Florida as long as the original purchase contract permits it. That is the critical starting point: you cannot assign a contract if the developer has prohibited it.

The First Question: Does the Contract Allow Assignment

Every pre-construction contract I have reviewed treats assignment differently. Some developers in Miami flatly prohibit assignments altogether. Others allow them but require written consent, charge an assignment fee ranging from 1% to 2% of the original purchase price, and demand that the new buyer qualify through their own approval process. A few, particularly smaller boutique developers, are relatively flexible and simply want to confirm the assignee has the financial capability to close.

Before a seller thinks about marketing their contract, and before a buyer considers offering a premium for one, we pull the original purchase agreement and read the assignment clause carefully. I have seen contracts where the developer retains the right to pocket any profit above the original purchase price. I have seen clauses that trigger the full forfeiture of deposits if an unapproved assignment is attempted. These are not hypotheticals. They happen.

If the contract is silent on assignment, Florida law generally permits it unless there is a specific prohibition. But silent does not mean easy. Developers can still slow-walk consent or make the approval process difficult enough to derail a deal. In my experience, the cleanest assignments happen when the developer has an established, written assignment policy with a defined fee and a defined timeline for approval.

How the Money Works in a Miami Condo Assignment

Let me walk through a real scenario. A buyer signed a contract in 2022 for a two-bedroom unit in a Brickell tower at $1,100,000. She put down 30% in staged deposits over 24 months, totaling $330,000. By 2025, the building is nearly complete and comparable units in the same building are under contract at $1,400,000. She wants to relocate to New York and needs liquidity.

An assignment deal in this case typically works like this. The assignee pays the assignor the original deposits already paid ($330,000) plus an agreed premium reflecting the appreciation in value. If the parties agree the contract is now worth $1,350,000, the assignee pays the assignor roughly $580,000 at the assignment closing, which includes the $330,000 in deposits plus a $250,000 premium. The assignee then owes the developer $770,000 at the final construction closing to complete the $1,350,000 total, along with the usual closing costs.

The developer may charge an assignment fee, say 1.5% of the original price, or $16,500 in this scenario. That fee is typically paid by the assignor, though it is negotiable. Title is handled by a Florida closing agent, and because no deed transfers at the assignment stage, documentary stamp taxes on deeds do not apply until the final deed transfer at the construction closing. The assignee should still plan for their own closing costs at that final closing, which in Miami typically run between 2% and 4% of the purchase price depending on financing.

What Buyers Gain and Risk When Purchasing an Assignment

For a buyer, an assignment can be genuinely attractive. You are acquiring a unit in a nearly complete or recently completed luxury building without waiting years for the next pre-construction cycle. You may also be buying at a price below what comparable delivered units are selling for on the open resale market, because the assignor wants a quick exit and values liquidity over maximum profit.

The risks, though, are real. You inherit the original contract in full, which means you inherit whatever terms the original buyer accepted. If the original contract had unfavorable cancellation terms, limited recourse on developer delays, or broad developer rights to substitute finishes, you are bound by those terms. You cannot renegotiate with the developer simply because you are a new party.

Financing is another challenge. Most traditional lenders will not issue a mortgage commitment on a unit that has not yet received its certificate of occupancy and has not been conveyed by deed. If you are an assignee planning to use a mortgage, confirm with your lender early that they will fund the final closing even though you were not the original contract buyer. Some lenders require additional documentation. Others will not do the deal at all, which makes all-cash buyers the dominant players in true assignment transactions.

I always recommend that buyers getting into an assignment transaction also verify the developer's construction progress, the projected closing date, and any outstanding litigation involving the building or the developer. A pre-construction contract is only as good as the developer standing behind it.

What Sellers Need to Know Before Listing a Contract

If you are the original buyer and you want to assign your contract, the first call you make should not be to a random agent listing it on Zillow. The first call should be to your real estate attorney to confirm what your contract allows and what the developer approval process looks like. The second call should be to a Miami agent who has actually closed assignment transactions, not just heard about them.

Tax treatment is an important consideration that your accountant needs to weigh in on. The gain on an assignment is generally treated as ordinary income or capital gain depending on your holding period and your relationship to the underlying asset. For foreign sellers, FIRPTA withholding rules may apply even on an assignment transaction, though the specific application depends on the structure. I am not a tax advisor, but I flag this every time because I have seen clients get surprised by a tax bill they did not budget for.

Pricing an assignment correctly requires knowing current market conditions in that specific building, in that specific floor range, with that specific view. Overpricing an assignment in a market where there are five other units for sale in the same tower is a quick way to sit unsold until the developer's closing deadline forces your hand. I pull sold comps, pending contracts, and current inventory in the building before recommending a price to any assignor.

Key Steps in the Assignment Process

I walk every client through a clear sequence of steps so the process does not feel overwhelming. Here is a general outline of what to expect from start to finish.

Assignment transaction checklist for Miami pre-construction condos:

• Review the original purchase contract for the assignment clause and any developer consent requirements.
• Contact the developer's sales office or legal department to confirm the assignment approval process, required documentation, and applicable fees.
• Engage a Florida real estate attorney to review the assignment agreement before signing.
• Work with an experienced Miami agent to price the contract based on current comparable sales and active inventory in the building.
• Market the assignment to qualified buyers, often through agent networks since major listing portals do not always accommodate pre-construction assignments cleanly.
• Secure developer approval in writing before any funds change hands.
• Execute the assignment agreement with a Florida title company handling escrow.
• Assignee prepares financing (if applicable) for the final developer closing.
• Final deed transfer occurs at the construction closing, where all remaining balances, closing costs, and any documentary stamp taxes are settled.

Miami Neighborhoods Where Assignment Deals Are Most Active

Not every Miami neighborhood sees the same volume of assignment activity. The neighborhoods where I see the most pre-construction assignment deals are Brickell, Edgewater, Sunny Isles Beach, and the Miami Beach corridor from South Beach up to Mid-Beach.

Brickell and Edgewater attract a high share of international buyers who purchase multiple units speculatively. When market conditions shift or personal priorities change, those buyers look to exit through assignments before closing. Towers like One Brickell City Centre, St. Regis Brickell, and the Mercedes-Benz Places project have generated significant assignment interest.

Sunny Isles has historically been a market where Venezuelan and Argentine buyers concentrate, and currency and political changes in those countries directly affect the assignment market. When the Argentine peso falls sharply or capital controls tighten, I see more assignment listings appear from buyers who need to right-size their Miami exposure.

In Miami Beach, assignments tend to involve higher dollar amounts and more scrutiny from developers, but they do happen. Buildings in the $2 million to $6 million range for single units see assignment premiums that can reach $300,000 to $700,000 depending on the floor and view. These are genuine wealth-building opportunities for buyers who move quickly when they appear.

Common Mistakes I See in Assignment Transactions

The most expensive mistake I see is a seller marketing an assignment without first confirming developer consent is even possible. I have seen buyers pay a premium for a contract only to have the developer deny the assignment because the original contract prohibited it. The result is a dispute, legal fees, and a deal that falls apart. Always get the developer's position in writing before listing.

On the buyer side, the most common mistake is failing to read the original purchase contract in full before agreeing to an assignment price. I worked with a buyer who was thrilled with the per-square-foot price on an assignment in a Brickell tower, only to discover after reviewing the contract that the original buyer had agreed to an upgrade package valued at $180,000 that was non-refundable and non-transferable. The assignee was inheriting a contract for finishes that were gone. The deal still made sense, but only at a renegotiated price.

Finally, I see buyers underestimate the timeline. Developer approval can take two to six weeks. Final construction closings can be delayed by permitting issues, certificate of occupancy delays, or punch-list items. If you are an assignee counting on a specific move-in date, build flexibility into your plans. Miami construction timelines are rarely as precise as the developer's marketing suggests, and that is just the reality of building in a city with significant permitting complexity.
