If you read the listings sites, Tulum is a real-estate market. If you sit through the Cabildo, you discover it is a municipal project — under-funded, contested, and constantly re-negotiated in public. The decisions made in those rooms move prices in ways no MLS captures, and the vast majority of buyers find out months later, usually from a broker, usually too late.
We spend our weeks reading every public session. Here are 10 files we are tracking right now that almost nobody outside the building is talking about. Most of them are not crises. A few are. All of them are pricing-relevant — meaning the brochure number you saw last weekend already does not reflect what the seller, the broker, or even the city itself knows.
1. The fiscal hole is wider than the public statements suggest
Year-end 2025 revenue came in 16.5 million pesos below target — a 1.29% shortfall after mid-year projections showed on-pace collection. On top of that, a 72.4 million peso management deficit was registered, and the municipality took a 50 million peso loan in December while the treasury publicly claimed healthy finances. This matters for buyers because every "the city will install" promise on a brochure is implicitly funded against this balance sheet.
2. The síndica has refused to sign the public accounts
This is not a rumor — it is a formal, documented refusal. The síndica refused to sign the 2025 cuenta pública, citing contradictions between internal payroll documents that showed budget insufficiency and public statements claiming a surplus. She asked, on the record:
Por un lado, documentos oficiales señalan que no alcanzaba el dinero para pagar la nómina. Por otro lado, se habla de finanzas sanas y un superávit. Entonces la pregunta es, ¿a cuál versión le creemos?
"On one hand, official documents indicate there wasn't enough money to pay payroll. On the other hand, they talk about healthy finances and a surplus. So the question is, which version do we believe?"

This shapes which permits move and which stall, which neighborhoods get prioritized for public works, and which projects suddenly get re-litigated.
3. Beach-access compliance is failing in writing
Mexico's federal beach-access regime is more aggressive than most foreign buyers realize, and Tulum has been formally cited for compliance gaps. Over 50,000 people have visited the new free-access beach points since they opened, and 1,109 foreign residents have been enrolled in the exemption program. This is not a pilot — it is an operating regime with federal backing.
4. Sargassum barriers are political, not just environmental
The decision to reject offshore barrier proposals is being framed as ecological. Listen to the sessions and a different story emerges — one about ownership, federal jurisdiction, and the fact that sargassum volume hit 1,220 tons in March 2026 vs. 462 tons the prior year, a 164% increase. Akumal residents are now organizing private barrier installation as a market-driven alternative, while the municipality has formally rejected the approach for the hotel zone.
5. Aldea Zama's security file is open again
A premium gated zone is not supposed to make the homicide column. It did — on April 18, 2026, two suitcases with human remains were reported on Calle Itzamná in Aldea Zama. The municipal security response has been documented. The zone had previously been tracking a 61% reduction in intentional homicides and two months of zero incidents. That record is now broken.
6. 10,000 to 30,000 vacation rental units are unsold
This is not our estimate — it comes from the president of AMPI Tulum (the local realtor association), on the record, in a January 2026 press conference. Production of studio and one-bedroom vacation rentals has stopped. Absorption is estimated at two and a half years. The developers that remain competitive are those with better locations and genuine value-add, not those with brochures.
Se hablaba de que por lo menos había entre 10 y 30 mil unidades de vivienda que no se habían vendido y que se encontraba estancado este sector.
"There was talk that there were at least between 10 and 30 thousand housing units that had not been sold and that this sector was stagnant."

7. Water and drainage capacity is a hard ceiling
The honest version of every "it's being installed" conversation is "we are queued for it." The Cristal Colony water network and drainage projects are active — Phase 1 potable water and Phase 2 sanitary drainage — but these are the kind of projects that demonstrate how long even funded infrastructure takes. Buyers reading "city water connection imminent" should ask the date and which session minuted it.
8. Fake construction permits are under formal investigation
The municipality has opened a documented investigation into fraudulent construction permits. This is not code enforcement — it is a permit-fraud case. For any buyer who was told "permits are in order," the honest follow-up is which office issued them and whether they appear in the municipal register. If a developer resists that question, that is signal.
9. The POEL is deciding which land you can build on — right now
Tulum is currently in Stage 4 of its POEL (ecological ordering plan) — the stage where the classifications are actually assigned. Protection, conservation, restoration, or sustainable development. Tulum's existing ecological planning instrument dates from 2001. Cancún and Solidaridad already replaced theirs with their own POELs. Tulum is behind, and catching up means every parcel gets a formal classification that constrains what can be built.
10. The market is shifting from nomads to families
The AMPI president documented it in the same January session: Tulum is converting from a digital-nomad and couples niche into a family-buyer market. Families want houses, villas, residences — not studios and one-bedrooms. The buyer demographic is now roughly 50% Mexican, 50% international (U.S., Canada, Latin America, Europe, and emerging Asian interest). If your investment thesis is still "studio for Airbnb," the demand profile has moved under you.
None of these files is going to scream from a brochure. All of them are public. Insider members get the synthesized view, the source quotes (original Spanish with English translation), and the zone-by-zone implications — every Friday, plus on-demand zone briefings.
