Buying a pre-construction lot in Mexico means paying today's phase price for land that already exists, usually through an interest-free developer payment plan, and receiving infrastructure and amenities later. The discipline is the same everywhere: verify permits yourself, read the delivery and penalty clauses, and ask the ten questions at the end of this guide before signing.
We write from the developer's side of the table — Selvadentro sells pre-construction lots in Tulum — so treat this as a disclosed first-party guide. The checklist below is the one we would want our own family to use, on any project, including ours.
How is a land presale different from a condo presale?
In a condo presale, you pay for something that does not exist yet; your main risk is that the building never gets finished. In a land presale, the lot already exists — what you are buying is phase pricing and time. The developer commits to delivering infrastructure and amenities around your land, and prices the early phases lower to fund that build-out.
That difference changes the risk profile. You still depend on the developer to deliver streets, utilities and common areas, but your underlying asset is a specific, measurable piece of land, not a promise of one. One concrete example of the price-and-time mechanics: at Selvadentro, the launch price in May 2025 was $119 USD per m²; today it is $167 USD per m², a 40% move in twelve months, with a projected $280–360 USD per m² at project close. Early buyers were paid for their patience — that is the entire logic of preventa.
How do developer payment plans work?
Bank mortgages on raw land in Mexico are rare, so developers finance buyers directly. The typical structure is a down payment plus fixed monthly payments over the sales period, at 0% interest — the "discount" for early buyers is the phase price itself, not the financing.
Selvadentro's disclosed example: 48 months, interest-free, directly with the developer, on lots from $68,000 USD. Here is what that entry price looks like under common down-payment structures. This table is illustrative — down payments vary by developer and negotiation; confirm your exact schedule in writing:
| Structure (illustrative) | Down payment | 48 monthly payments | Total |
|---|---|---|---|
| Straight 48-month split | $0 | $1,417 USD | $68,000 USD |
| 10% down | $6,800 USD | $1,275 USD | $68,000 USD |
| 20% down | $13,600 USD | $1,133 USD | $68,000 USD |
| 30% down | $20,400 USD | $992 USD | $68,000 USD |
Two things the table does not show. First, closing costs: in the Riviera Maya they typically run 6–8% of the purchase price (acquisition tax, notary, registry), and foreign buyers in the restricted zone add a fideicomiso — a 50-year renewable bank trust, standard since Mexico's foreign investment framework of 1973 and 1993, with an annual bank fee typically of $500–700 USD. Second, ongoing dues: ask for the HOA rate in writing (at Selvadentro it is about 5 MXN per m² per month, plus a trust reserve for long-term maintenance).
What are the real risks — and what should you ask?
These are questions to raise with the developer and your own notary or lawyer, not legal advice.
Permits. The single biggest risk in Tulum is a project without complete state and municipal authorization. In September 2025, Quintana Roo's urban-development authority SEDETUS publicly listed 26 Tulum developments over permit concerns — and five days later, on September 16, 2025, cleared 14 of them (Selvadentro included) after they proved full compliance. The lesson is not "avoid Tulum"; it is "verify, always." We wrote a step-by-step on exactly how to verify a Tulum development with SEDETUS, and our own documentation stance is on the legal compliance page.
Delivery obligations. The contract should state what is delivered — streets, power, water, security, amenities — and by when. A dated delivery obligation (Selvadentro's Suspiro: 2029) is enforceable; "estimated" language is not. Ask what happens if delivery slips: is there a penalty on the developer's side?
Penalty clauses in both directions. Read what happens if you stop paying. Is there a grace period? A refund of paid capital, and at what discount? A rescission penalty? None of these answers is automatically a red flag — the red flag is a salesperson who cannot answer them precisely.
Resale before delivery. Some contracts let you assign your rights before titling; some prohibit it or charge a fee. If your strategy involves exiting early, know this before signing, not after.
What do green flags look like?
Signals that a preventa developer is likely to deliver:
- Delivered history. Prior phases sold and handed over. At Selvadentro, two enclaves — Mirador and Refugio — are fully sold, and the founding family previously developed Aldea Zamá and Yucatán Country Club. Ask any developer the same question: what have you finished?
- Verified compliance. Named in the September 16, 2025 SEDETUS updated bulletin as compliant, in our case. For any project: ask for the permit file, then verify it independently.
- Rules that bind everyone. Building regulations (density, coverage, levels) written into the community regime protect your resale value from your neighbors' worst ideas.
- A knowable counterparty. A developer with names, a track record and a physical office — see who is behind Selvadentro — is answerable in a way an anonymous SPV is not.
The 10 questions to ask any developer
- Which state and municipal permits does the project hold, and can I see copies?
- Does the land use (uso de suelo) actually allow the residential master plan being sold?
- Who holds title today, and how exactly does it transfer to me — deed or fideicomiso?
- What is delivered, and is the delivery date a contractual obligation or an estimate?
- What penalty does the contract impose on you if delivery is late?
- What happens if I miss payments — grace period, refund terms, rescission penalty?
- What have you delivered before — phases, projects, communities I can visit?
- What building rules bind every owner, and who enforces them after handover?
- What are the HOA dues, what do they fund, and is there a maintenance reserve?
- Can I resell or assign my contract before delivery, and at what cost?
A developer comfortable with all ten is telling you something. So is one who is not.
Is preventa worth it?
When the permits check out and the developer has history, preventa is how you trade patience for price — the investment math only works because you enter before the infrastructure does.
