Can You Sell a Mexico Pre-Construction Condo Before Delivery? How Contract Assignments Work for Foreign Buyers

TL;DR / Key takeaways

• In many Mexico pre-construction deals, you can sell your position before delivery through a contract assignment, often called a cesión de derechos (assignment of rights).
• Whether you can do it, and on what terms, depends on your contract. Many developers require written consent, may charge an assignment fee, and sometimes restrict assignments until a set share of the price is paid or the developer's own inventory is sold.
• An assignment is not the same as selling a titled property. The buyer steps into your contract, not into a deed, so the paperwork, timing and taxes work differently.
• Check the assignment clause before you sign, not when you want to exit. A notario, a Mexican real estate attorney and a tax advisor should confirm the details for your situation.

Can you sell a Mexico pre-construction condo before it is delivered?

Often, yes, but only if your contract allows it. When you buy off-plan in Mexico, you usually do not own a deeded unit yet. You hold contractual rights: the right to receive a specific unit at a specific price once construction is finished and title can be transferred. Selling before delivery means transferring those rights to a new buyer. That transfer is generally done through an assignment of rights, known in Spanish as a cesión de derechos.

The key point is simple: the developer's contract sets the rules. Some contracts allow assignments freely, some allow them only with the developer's written approval, and some prohibit them or delay them until a later stage. Read that clause the same way you read the price and the delivery date.

Why foreign buyers ask about assignments

Plans change during a construction timeline that can run for a year or more. Buyers in Canada, the United States and Europe typically ask about an assignment for a few reasons:

• Exit flexibility. A job change, a family situation or a new plan can make holding the unit until delivery less attractive.
• Investment strategy. Some investors buy early in a pre-sale phase with the idea of assigning later. This is a strategy with real risk, not a guaranteed outcome.
• Avoiding a default. If you can no longer make the remaining payments, an approved assignment can be a cleaner path than walking away under the contract's penalty terms.

Assignment vs resale after delivery: what is different

An assignment happens while the project is still being built and before the deed is signed in your name. A resale happens after you have taken title, usually through a deed signed before a notario and, for restricted-zone property near the coast, often held through a fideicomiso (bank trust).

• What is transferred. In an assignment, the new buyer takes over your contract and your payment history. In a resale, the new buyer acquires the titled property.
• Who must agree. An assignment usually involves three parties: you, the new buyer and the developer. A resale is between you and the buyer, with the notario formalizing it.
• Paperwork. An assignment is typically documented with an assignment agreement and the developer's acknowledgement. A resale goes through the full closing process.
• Taxes. The tax treatment of a gain on an assignment can differ from the treatment of a sale of titled property. Ask a Mexican tax advisor, and your home-country advisor, how it applies to you before you agree on a price.

What to check in your pre-sale contract before you sign

The best time to think about an assignment is before you sign the promissory or pre-sale agreement. Ask the developer, or have your attorney check, these points:

• Is assignment allowed at all? Look for a clause on cesión de derechos, transfer or assignment.
• Is developer consent required? If yes, ask whether consent can be refused and on what grounds.
• Is there an assignment fee? Ask how it is calculated and who pays it, you or the new buyer.
• Are there timing limits? Some contracts block assignments until a certain payment level is reached, until a sales milestone, or near delivery.
• Are there marketing limits? Some developers restrict how or where you can advertise an assigned unit, or ask that you not undercut their current price list.
• What happens to your deposit and payment history? Confirm that payments already made are credited to the new buyer's position.
• Who signs the final deed? Confirm that, after an approved assignment, the new buyer will be the one who takes title at delivery.

How an assignment usually works, step by step

1. Review your contract with your attorney to confirm what is allowed and what the developer requires.
2. Request the developer's conditions in writing: forms, fee, documents needed from the new buyer and approval timeline.
3. Find a buyer and agree on the terms, including what the buyer pays you for the payments you have already made and any premium.
4. Sign an assignment agreement drafted or reviewed by a professional, and obtain the developer's written approval.
5. Handle the money safely. Use traceable transfers and, where possible, escrow or a structure your attorney recommends. Never send funds based on instructions from an unverified email.
6. Get confirmation from the developer that its records now show the new buyer as the holder of the contract.

Risks to understand before counting on an assignment

• No guaranteed buyer. Demand for assignments depends on the market, the project and the developer's own pricing at the time.
• Competing with the developer. If the developer still has units for sale, your assignment may compete with its inventory.
• Costs reduce your net result. Assignment fees, professional fees and taxes all come off what you receive.
• Contract delays. If delivery slips, your exit timing can slip too. Our guide on what happens if your pre-construction condo is delivered late explains delay clauses.
