A Tulum pre-construction investment asks you to pay for a home that does not yet exist, on land you have not yet examined, under permits you may never see unless you ask. In 2026 that request comes in a market with more unfinished stock than buyers, which gives you negotiating room and raises the cost of a mistake. This checklist sets out the documents to obtain and the questions to put, in order, before any money moves. For the wider legal framework, read our guide to buying property in Mexico as a foreigner first.

Why buyers consider a Tulum pre-construction investment

Pre-sale (preventa) appeals for familiar reasons: a lower entry price than a finished unit, payments spread over the construction period, and the chance to choose a unit early. Those advantages are real only if the project is completed on time, as specified, with title that can be transferred.

The market context in 2026 favours caution. An InfoHabitat analysis built on Softec and federal tourism data, reported in July 2026, found that housing units under construction in Tulum rose from 1,466 in 2017 to 13,266 in 2023, while annual sales fell from 3,487 in 2023 to 1,711 in 2025. Passenger traffic at Tulum's airport fell in early 2026, and several international routes were cut. Developers with slow sales have less cash coming in to finish buildings, which is exactly the risk a pre-sale buyer carries.

None of this rules out a good purchase. It means the paperwork has to carry more of the weight.

Title and land checks

Start with the land, because a building cannot be better than the title beneath it.

Registered ownership. Ask for the deed (escritura) and the folio real number in the Registro Público de la Propiedad of Quintana Roo. Confirm who owns the land today: the developer, a landowner partner, or a bank trust created for the project.
Liens. Obtain a current certificate of no liens (certificado de libertad de gravámenes). Construction loans and guarantees are common and not necessarily a problem, but you need to know how your unit will be released from them at delivery.
Origin of the land. If the land was once ejido, confirm that it was converted to full private ownership (dominio pleno) and registered as such. Our guide to ejido versus titled land explains how to check.
Development trust. Where the project sits in a bank trust, ask for the trust agreement, the trustee bank's name and the instruction rules for releasing units and funds.

Have a notario público or an independent lawyer review these documents. A developer's sales office is not a substitute.

Building and environmental permits

Urban planning in Tulum

Tulum's planning framework has been unsettled. The council approved a new Programa de Desarrollo Urbano in September 2024, published on 20 September 2024, then voted in 2025 to set it aside until a local ecological zoning programme (POEL) is completed. Under that decision, the 2006–2030 urban development programme and the partial programme for the southern polygon remain in force. Ask the developer which instrument its land-use approval relies on, and have your lawyer confirm it is valid.

The documents to request are the land-use licence (licencia de uso de suelo), the construction licence for the building you are buying, and any condominium or subdivision authorisation. Check that the number of units and floors in the sales brochure matches the licence.

State registry of irregular projects

The Quintana Roo urban development ministry, SEDETUS, publishes a registry of developments it considers irregular, typically for advertising without the state's urban congruence certificate (Constancia de Congruencia Urbanística Estatal) or municipal permits. In October 2026 the registry listed 137 entries, including several in Tulum added in August and September 2026. Search it by project name before you sign, and search for the developer's other projects too.

Environmental authorisation

Under Article 28 of the federal environmental law (LGEEPA), real-estate developments that affect coastal ecosystems, and land-use changes in forest or jungle areas, require prior environmental impact authorisation from SEMARNAT. Other projects fall under Quintana Roo's own environmental law and state authority. Tulum's municipal permits for clearing vegetation have required a copy of the federal or state environmental authorisation, or a documented exemption. Ask for the resolution itself, check its conditions and expiry, and confirm that the project as built matches what was authorised.

NOM-247-SE-2021 and PROFECO-registered contracts

The federal standard NOM-247-SE-2021 was published in the Diario Oficial on 22 March 2022 and became enforceable on 18 September 2022. It applies to developers, builders, promoters and others who advise on or sell homes to the public, and PROFECO, the federal consumer agency, verifies compliance. Key points for a pre-sale buyer:

Registered contract. A pre-sale must be made under an adhesion contract that meets the standard's minimum content and is registered with PROFECO. Ask for the registration number and check it in PROFECO's public registry of adhesion contracts. Then compare the document you are given with the registered model, clause by clause.
Deposits. The developer must give a receipt for any deposit (anticipo) and explain, before you pay, how it will be credited, and how and when it can be refunded, including any penalties.
Disclosure. During a pre-sale the developer must display the price and features of the homes clearly, and must have enough financial capacity to meet claims on units already pre-sold.
Delivery and penalties. PROFECO-registered pre-sale contracts typically set a delivery date and a conventional penalty (pena convencional) for late delivery. Make sure both are filled in with real figures, not left blank.

Payment schedule and escrow

NOM-247 sets disclosure and contract rules. It does not, by itself, require that your money be held in escrow. That protection has to be negotiated.

Pay into the project, not a person. Payments should go to the developer's corporate account or, better, to the project's bank trust. Never pay a salesperson, a personal account or in cash.
Tie payments to progress. A schedule linked to verifiable milestones (structure complete, envelope closed, finishes installed) protects you better than a calendar schedule. Ask who certifies progress.
Escrow or guarantee. Ask whether funds sit in a trust or escrow arrangement with release conditions, or whether a bond or guarantee covers refunds. If the answer is no, price that risk into the deal.
Costs at delivery. Transfer taxes, notary fees and, for foreign buyers in the restricted zone, the cost of setting up a fideicomiso are usually paid at deed signing, which may be years after the contract. Budget for them now; our closing costs guide sets out the items.

As a reference point, Ownext's Casa Selva Alta is a house in Región 15 offered in pre-sale at MX$6,200,000, with construction 40% complete. Whatever you consider, the same checks apply, and buying into a project already well advanced shortens the period in which your money is at risk.

Exit and resale

Plan the exit before you sign. Two questions matter most.

First, can you sell before delivery? Many pre-sale contracts allow an assignment of rights (cesión de derechos) only with the developer's consent and a fee. Read the clause and get the fee in writing. Remember that during construction you will be competing with the developer's own unsold units.

Second, what is the market for the finished unit? With annual sales in Tulum roughly halved between 2023 and 2025, resale times can be long. If you intend to rent, Quintana Roo requires vacation-rental hosts to register with the state tourism registry, and platform-booked stays carry state lodging tax. Check rental data for the specific area on AirDNA rather than relying on a sales projection. Our comparison of land versus condo returns covers holding costs and liquidity in more detail, and our Maya Train guide puts Tulum's infrastructure in context.

Finally, keep every receipt, contract and permit copy. You will need them at deed signing, and again when you sell.

Checklist

Check the market and the developerReview recent sales and supply data for Tulum, then search the project and the developer's other projects in the SEDETUS registry of irregular developments.
Verify title and liensObtain the deed, the folio real in the Quintana Roo public registry and a current certificate of no liens. Confirm who owns the land and how your unit will be released from any construction loan.
Confirm the land's originIf the land was ejido, confirm it was converted to full private ownership (dominio pleno) and registered. If the project is in a bank trust, request the trust agreement.
Review urban and building permitsRequest the land-use licence, construction licence and any condominium authorisation, and confirm which urban development programme they rely on, given that Tulum's 2024 programme was set aside.
Review the environmental authorisationAsk for the SEMARNAT or state environmental impact resolution, check its conditions and expiry, and compare it with the project being sold.
Check the PROFECO-registered contractGet the PROFECO registration number, compare the contract with the registered model, and confirm deposit receipts, refund terms, the delivery date and the late-delivery penalty.
Structure payments and plan the exitPay only into the developer's corporate account or project trust, tie payments to construction milestones, budget for closing and trust costs at delivery, and read the assignment-of-rights clause before signing.

Questions investors ask

Is buying pre-construction in Tulum risky in 2026?

It carries more risk than in a rising market. An InfoHabitat analysis found annual home sales in Tulum fell from 3,487 in 2023 to 1,711 in 2025 while thousands of units remained under construction, so completion and resale risk deserve close attention.

What is NOM-247-SE-2021?

A federal standard, enforceable since 18 September 2022, that sets information, advertising and minimum contract requirements for people who sell homes to the public. Pre-sales must use an adhesion contract registered with PROFECO.

How do I check a developer's PROFECO contract?

Ask for the registration number, look it up in PROFECO's public registry of adhesion contracts, and compare the registered model with the contract you are asked to sign.

Does Mexican law require escrow for pre-sale payments?

NOM-247 requires receipts, refund terms and adequate financial capacity, but it does not by itself require escrow. Ask whether payments go into a project trust or escrow with release conditions, and negotiate for it.

How can I tell if a Tulum project has permits?

Ask for the land-use licence, construction licence and environmental authorisation, and search the project and developer in the SEDETUS registry of irregular developments. Have a notario or independent lawyer confirm the documents.

Can I resell a pre-sale unit before delivery?

Often only through an assignment of rights that needs the developer's consent and a fee. Read that clause before signing and get the fee in writing.
