Scoring Methodology
Every score on this platform is an auditable object. This page explains exactly how zone scores are constructed, what data sources we use, how confidence labels are assigned, and how often scores are updated.
Higher scores indicate lower composite risk and stronger market fundamentals. A score of 90.2 (Cancun) reflects strong infrastructure, low ejido exposure, and positive momentum. A score of 70.4 (Bacalar) reflects elevated ejido risk, pre-sale delivery concerns, and thin liquidity — not that the market is bad, but that the risk profile requires more careful due diligence.
Measures oversupply risk, pre-sale delivery track record, and active pipeline vs absorption rate.
Measures legal title clarity, ejido exposure, coastal permit stability, and AMPI compliance density.
Measures demand signals, price trajectory, STR occupancy trends, and foreign buyer flow.
Measures road connectivity, utility reliability, healthcare access, and planned public investment.
Every data point on this platform carries a confidence label. This tells you how much independent verification sits behind the signal.
Alerts are forward-looking signals. They surface information that may not yet be reflected in official records but is material to a buying decision.
| Source | Type | Use |
|---|---|---|
| RAN (Registro Agrario Nacional) | Primary | Ejido status, PROCEDE regularization records |
| SEMARNAT permit database | Primary | Coastal development permits, environmental impact declarations |
| RPPC (Registro Público de la Propiedad y del Comercio) | Primary | Property ownership records, fideicomiso filings |
| AMPI chapter registries | Primary | Agent and agency certification status |
| ASUR (airport authority) | Primary | CUN passenger volume data (quarterly) |
| SECTUR tourism statistics | Primary | Hotel occupancy, tourist arrivals, seasonality |
| Google Business Profile | Secondary | Participant ratings, review counts, operational signals |
| Municipal permit records | Secondary | Construction permits, land use authorizations |
| PROFECO | Secondary | Developer consumer complaints, breach of contract filings |
| Riviera Audit field research | Proprietary | On-ground verification, local source interviews, site visits |
We build features to a source-verifiability bar, not a "looks plausible" bar. When a metric can't be reliably sourced, we pull it — publicly, with the reason — instead of leaving it live with synthesized numbers.
Built a collector to measure price-cut magnitude, pre-sale vs. resale gap, beachfront premium, and cross-portal price spread across Lamudi, Point2Homes, and Inmuebles24. Tested it live against all 8 zones and confirmed the underlying search method cannot reliably extract portal-attributed, listing-level figures from those sites. Pulled the feature — including its dashboard page and nav entry — rather than publish estimates we could not stand behind.
A verdict or risk flag about a named participant is the highest-stakes thing this platform publishes — it can affect a real business's livelihood, and every source feeding it (public filings, web search, AI extraction) can be wrong. We hold negative flags to a real evidence bar before they publish, and we commit to correcting the record — publicly, not quietly — whenever we get one wrong.

Current: The active scoring methodology. All published zones use this version. Scores are updated weekly.
Legacy: Previous versions still supported. Historical scores used these rules. Safe to reference in archives.
Deprecated: No longer in use. Scores from this era should be compared with caution due to methodology changes.
Note: Score deltas (week-over-week changes) are only calculated within the same methodology version to avoid comparing apples to oranges.
