The English guides that rank for "real estate scams in Mexico" get the big themes right. Forged deeds, developers commingling deposits, anyone who suggests skipping the fideicomiso. What almost none of them do is hand you the free public databases the Mexican authorities actually publish, the ones that answer most of those questions before you wire anything. You can check whether a development has been flagged for operating without permits, whether the person selling to you holds a current state license, and whether the pre-construction contract you are about to sign is registered with Profeco.
The scale of the problem is documented, not rumored. In March 2026, José Alberto Alonso Ovando, head of Quintana Roo's Secretariat of Sustainable Urban Territorial Development (Sedetus), reported that the agency had identified 118 irregularly subdivided sites during 2025 and early 2026, concentrated in Tulum, Isla Mujeres, Playa del Carmen and the municipality of Benito Juárez (Por Esto, 7 March 2026). Five months earlier the agency had 116 developments formally flagged, three advisors detained that year, and fines from 1,000 to 5,000 UMA (24 Horas Quintana Roo, 8 October 2025).
And in 2024, Estrella Ríos Pérez, president of the Quintana Roo chapter of the National Association of Corporate Lawyers (ANADE), said seven out of ten people who come to them after buying in Tulum, Playa del Carmen or Cancún had been victims of fraud, and that the most frequent case is the foreigner who buys ejido land believing they will be able to build on it (24 Horas Quintana Roo, 10 October 2024).
We work out of Playacar Phase II and operate as a wholesale broker in Playa del Carmen, Tulum, Cozumel and Cancún. These are the ten signals that make us stop a transaction, roughly in the order they show up.
1. The development is on the flagged list
Sedetus runs a public lookup at desarrollo.sedetus.gob.mx/consultaDesarrollos. It lists projects operating without the opinions, permits and authorizations required by the state's Human Settlements Law, Urban Works Law and Condominium Property Law. Read the result carefully. If the development appears, that is a no. If it does not appear, that is not a clean bill of health: it means the project has not been inspected yet. The list grows through inspection cycles, it is not a closed registry. Absence is not certification.
2. You are offered a possession certificate instead of a deed
This is the most expensive local trap and the best disguised, because the word "notary" appears in it. On 11 May 2026, Por Esto documented land sales in Playa del Carmen where the buyer receives only a notarized possession certificate while the lot legally stays in the developer's name. Biologist Gabriel Robles Medina, quoted in that report, warned that those lots offer no legal certainty, and the registry framework says the same thing in other words.
A possession certificate records that someone occupies a property. It does not transfer ownership. Ownership transfers through a public deed recorded at the Public Property Registry. If the seller cannot get you to that deed, they are not selling you a home. They are selling you an expectation.
3. The lot sits outside the Urban Development Program
The same investigation found lots with no potable water, no sewer and no electrical infrastructure, located outside the PDU. The consequence is rarely spelled out: the municipality cannot extend infrastructure into a zone its own program does not contemplate. It is not slow, it does not apply.
Ask directly and in writing: which zone of the current PDU does this lot fall in, and what land use is authorized for it? If the answer is a detour about future regularization, press for the zone number. They will not give it.
4. It is ejido land without full title, and they say it will be sorted out later
A foreigner cannot be an ejidatario or an avecindado: both require Mexican nationality under the Agrarian Law. And parcel rights can only be transferred to other ejido members or residents of the same nucleus, so no outside third party acquires them validly, Mexican or not. The assignment-of-rights contract sold to outside buyers transfers nothing enforceable.
For a parcel to leave the regime it takes the assembly and dominio pleno (full title); the National Agrarian Registry then issues the title, it is recorded at the Public Property Registry, and only afterward comes the deed. Watch the second filter too: full title solves the agrarian problem, not the constitutional one. In the restricted zone a foreign buyer still needs a fideicomiso.
The phrase that should trigger the alarm is "the paperwork is already in process": the risk of it never finishing would be yours.
5. Someone suggests skipping the fideicomiso
The restricted zone is not just the coast: it is 100 kilometers along the borders and 50 along the beaches, under Article 27 of the Constitution. In Quintana Roo both apply, because of the border with Belize. A foreigner cannot hold direct title there, and the normal route is a bank trust with a permit from the Ministry of Foreign Affairs.
When somebody proposes a private contract to save you the fideicomiso, it is usually because the property would not survive the trustee bank's review. The fideicomiso is not an obstacle, it is a free audit.
Be careful with the Mexican-company shortcut as well. Only a company with a foreigner-exclusion clause acquires direct title freely; one that admits foreign shareholders may acquire in the restricted zone for non-residential purposes, but for housing it still needs a fideicomiso. We cover it in the fideicomiso guide for foreign buyers.
6. The pre-construction contract has no Profeco registration number
Article 73 of the Federal Consumer Protection Law requires developers, builders and promoters to register with Profeco the standard-form contract they use to sell housing intended as a residence, and the same covers timeshare. It does not cover land not intended for housing, nor resales between private parties.
Where it applies, the registry is public at rpca.profeco.gob.mx. Ask for the number and verify it. The contract you sign must match the registered model, and here is what matters most to you: a contract that should have been registered and was not does not produce effects against you, and any deviation from the registered text is treated as not written. On the clauses that matter in pre-construction, see our Riviera Maya pre-sale guide.
7. The person selling has no current license
The law in force is the Real Estate Services Law of the State of Quintana Roo published on 6 September 2024, which repealed the 2014 statute. The license runs for two or four years, with a non-extendable thirty calendar day window to renew it. Holding yourself out as a real estate service provider without a license carries a fine of five hundred to one thousand UMA, and the general catalogue reaches suspension of up to ninety calendar days and cancellation with removal from the registry for three years.
There are two public lookups and it is worth running both: the registry of licensed advisors and the lookup for people holding themselves out as licensed without being so. The second one is the one almost nobody uses and the one that settles a doubt fastest.
8. The deposit goes to a personal account, or is requested before you see documents
The correct order is documents first, money second.
When someone asks for a deposit to hold a unit before showing you the ownership chain, or when the receiving account is in an individual's name rather than the company signing, you are financing a stranger with no collateral.
And an imported assumption worth dismantling: title company escrow, as used in the United States, is not the standard in Mexico. Assuming your money sits there is one of the most common ways to lose it. Which payment lands when, and what you sign at each stage, is in our step by step buying guide.
9. The price is far below the area and comes with a deadline
This warning appears in nearly every guide, though rarely with its counterweight: a low price is not suspicious on its own. There are genuine distressed sales and units with defects that are honestly discounted.
What is suspicious is the combination: an anomalous price, time pressure, an informal channel (a social media ad with no address and no registered company name), and resistance to letting a third party review the paperwork. Calibrating what counts as anomalous needs a per-area reference, not a city average, which is the work behind our Playa del Carmen neighborhoods guide.
10. There is no recent lien-free certificate
Double sales and forged deeds are two of the schemes we see most, and it is worth understanding exactly what protects you from each, because it is not the same document.
The lien-free certificate is indispensable, and it should be reissued on the day of signing. But it shows only what is recorded as of that hour: registered owner, mortgages, attachments, annotations. An earlier sale that was never recorded is invisible there, and that is the gap a double sale walks through.
What protects you against a double sale is registry priority, triggered by the preventive notice the notary files before signing. Against a forged deed, comparing the testimonio against the authorizing notary's protocol and walking the registry antecedents backwards. If the seller does not have those documents, they can be requested. If they will not request them, they have answered you.
When we say no
We do not work on land without documented full title, on lots outside the PDU, or with developers who cannot show current permits. Nor when a seller makes document review conditional on a deposit landing first. We have lost transactions this way and we would lose them again: a closing that never happened costs nothing; a deed that cannot be recorded costs the entire purchase price plus years of litigation.
Our own developments, BUZZ on Calle 28 in Playa del Carmen, RAXÁ in Tulum and THE STELLA in Cozumel, are reviewed against this same list, and the inventory is on our properties page.
The short version: three checks
Before any deposit, run these three:
| What you verify | Where | What it tells you |
|---|---|---|
| The development | desarrollo.sedetus.gob.mx/consultaDesarrollos | Whether it is flagged for operating without permits |
| The seller | consultaAsesores and consultaOstentados | Whether they hold a current license or are posing |
| The contract | rpca.profeco.gob.mx | Whether the standard-form contract is registered |
None of the three replaces review by an attorney or the notary, and none guarantees the deal is good. What they do is rule out, in one sitting, a good share of the people who should not be selling. If you want us to look at a file before you sign, get in touch and we will tell you what we find.
This guide is informational and is not legal advice. Every transaction needs review by a real estate attorney and by the notary who formalizes it.
