The decision that protects a preconstruction buyer in Mexico is where the deposit sits. Money wired to the developer’s own account is construction financing with your name on it: unsecured, spent, and recoverable only through Mexican courts if the project stalls. Money held by a third-party escrow provider against construction milestones survives a failed project. Every other check on this page, permits, contract registration, title, developer record, exists to answer one question: has this developer earned the right to touch your money before the deed exists?
What a presale legally is
A Mexican preconstruction purchase usually runs on a promise-to-purchase agreement signed long before any deed. You own nothing until the escritura is executed before a notario and recorded, and in the coastal restricted zone the closing also runs through a bank fideicomiso permitted by the Secretaría de Relaciones Exteriores. [Secretaría de Relaciones Exteriores, Secretaría de Relaciones Exteriores, Permisos para constitución de fideicomiso, Artículo 27 constitucional, 2026-08-12] Until that day, you hold a contractual claim against a company, and the claim is only as good as the company.
Consumer law does reach that contract. Article 73 of the Ley Federal de Protección al Consumidor places developers, builders, and promoters selling housing to the public under PROFECO’s jurisdiction, and it requires their standard-form contracts to be registered with the agency. [Cámara de Diputados del H. Congreso de la Unión, Ley Federal de Protección al Consumidor, Artículo 73, 2026-08-12] Since September 2022, NOM-247-SE-2021 has added teeth: it dictates what marketing for residential property must disclose, sets minimum elements for the purchase contract, and obliges the provider to honor advertised prices, terms, and delivery dates. [Secretaría de Economía, NOM-247-SE-2021, Diario Oficial de la Federación, 2022-03-22]
The gap between the law and the market is where buyers get hurt. Registration and disclosure rules bind developers who intend to be around for the enforcement. The ones worth fearing sell fast and restructure faster.
Two named failures worth studying
Selling before the permits exist. A buyer in an unpermitted project can pay in full and still be left unable to register the deed. In September 2025, Quintana Roo’s urban development ministry, Sedetus, named 26 Tulum developments selling without the state or municipal certificates, permits, or authorizations the law requires, warning that their title transfers were unlikely to succeed and that even connection to light, sewer, and public roads was not assured. Nova Tulum, Selvadentro, and Bosque Tulum sat on that list. [Riviera Maya News, Riviera Maya News, Government uncovers more than two dozen real estate developers illegally selling properties in Tulum, 2025-09-12] Twenty-six projects, one municipality, one announcement. Presales without permits are not an edge case on this coast.
Building through shutdown orders. The Adamar condominium project in Bahía Solimán, Tulum, built without federal environmental authorization and kept building through repeated inspections. On September 23, 2025, a criminal-court judge made the federal environmental agency Profepa custodian of the property, freezing construction while administrative and criminal responsibility gets sorted out. [Riviera Maya News, Riviera Maya News, Profepa wins Tulum real estate legal battle and becomes custodian of Adamar condo project in Bahía Solimán, 2025-09-25] The coverage says nothing about deposit refunds. There is rarely anything to say.
The developer file you build before signing
Run these in order. Each one is cheap relative to the deposit it protects.
| What the sales office says | What you demand instead |
|---|---|
| ”Permits are in process” | The municipal construction license and, for coastal projects, the federal environmental authorization, by document number, verified by your attorney |
| ”The land is secure” | The folio real at the state property registry and the title chain behind it, including any ejido conversion in the parcel’s history |
| ”Our contract is standard” | Proof the adhesion contract is registered with PROFECO, plus your attorney’s read of delivery dates, penalties, and refund triggers |
| ”Hundreds of happy owners” | The developer’s previous two projects by name, delivered when, and a conversation with an owner in each |
| ”Wire the reservation today to lock the price” | An escrow structure in writing before any money moves |
The title row matters more than buyers expect. A presale on land that never completed its agrarian conversion fails no matter how honest the developer is, which is why the land check comes before the developer check.
Escrow in Mexico is not what you assume
Mexican attorneys and real estate agents are not authorized to provide escrow services, so “the agent will hold your deposit” means an ordinary bank account, commingled with other funds and reachable by the holder’s creditors. The structure buyer’s-side firms recommend instead is a dedicated escrow provider holding funds in a segregated, insured account outside the developer’s reach, with releases tied to construction milestones rather than developer requests. [MexLaw, MexLaw, MexLaw Escrow Service Protects Your Real Estate Investment in Mexico, 2026-08-12]
Name the tradeoff: developers price presale discounts on the assumption they can spend your deposit as construction capital. A developer facing milestone escrow loses that float and will sometimes charge more or walk away. Pay the difference or lose the deal. A developer who refuses escrow outright has answered your due diligence question at no charge.
If the deal proceeds, move funds the boring way: documented, bank to bank, in the contract currency. Our guide to wiring money to Mexico covers the mechanics, and the closing-costs breakdown covers what stacks on top at escritura time.
Who should skip preconstruction entirely
Skip presales if you need the unit by a fixed date. Delivery slippage is normal even in honest projects, and your penalty clause will compensate you in pesos, not in time.
Skip them if losing the deposit would change your life. Escrow shrinks the risk; nothing removes it.
Skip them if you cannot see the site and the developer’s prior buildings in person, or if the rental projections in the brochure are doing the underwriting. Projections are marketing. The HOA and building-governance checks that decide whether a finished condo performs apply double to one that exists only as a render.
A completed unit with a clean deed, a functioning HOA, and a verifiable folio costs more per square meter than the presale beside it. That premium is the price of certainty, and for most buyers moving retirement money it is worth paying. Work with an independent attorney, separate from the notario, from the first document onward, and if the property sits in the restricted zone, read the fideicomiso guide before you price anything.

This article is for informational purposes only and does not constitute legal advice. A preconstruction purchase in Mexico turns on the promise-to-purchase contract, PROFECO registration under the Ley Federal de Protección al Consumidor and NOM-247-SE-2021, the escrow arrangement that holds your deposit, and, inside the restricted zone, the bank fideicomiso, and the documents of the specific project govern the result. Engage a Mexican real estate attorney who represents you alone, separate from the notario, before you sign a reservation or release any funds.
