How we calculate the Trust Score
Zero ambiguity. The full formula, the indicators we publish, and how they translate into a risk band. Published and auditable.
Three weighted pillars
The Trust Score is a weighted average of three components. Each component is independent and has its own indicator set on a 0–100 scale.
Compliance and Legal Certainty
Measures legal and consumer compliance verifiable from public data: PROFECO complaints and conciliations, RPCA-registered adhesion contract, and per-project municipal permits. This carries the highest weight because it is the foundation of any valid purchase.
Track Record and Performance
Measures how well the developer has delivered on past projects: time, quality, scope, and units delivered. Past delivery capacity is the best predictor of the next one.
Public Reputation
What real buyers and specialized press say. Reputation blends three sources with fixed weights: verified reviews (Bayesian-smoothed), media sentiment, and external aggregator ratings.
Compliance and Legal Certainty · 40%
These 18 indicators are our disclosure framework: each is marked verified, pending verification, or not applicable for every developer, against public sources. The Compliance score moves only on verifiable signals (PROFECO complaints and conciliations, RPCA adhesion-contract registration, per-project municipal permits, and official irregularity flags). A missing data point is shown as “pending verification” — never counted as a pass.
- PROFECO Buró Comercial — complaint, conciliation, and arbitration counts
- PROFECO — share of complaints resolved in favor of the consumer
- Municipal construction licenses per project
- Land-use certificate and utility feasibility
- Environmental Impact Statement (MIA) where applicable
- Federal SEMARNAT permits in coastal or protected zones
- Adhesion contract registered with PROFECO
- Compliance with NOM-247-SE-2021 (mandatory clauses)
What moves the Compliance number
Full transparency: the Compliance score starts from an unverified baseline (55/100) and moves only on verifiable public evidence. We never reward missing data.
- Per-project permits (c8–c11) → Each confirmed municipal permit adds; a permit reported as rejected subtracts.
- PROFECO complaints — Buró Comercial (c1) → A verified record with no complaints adds; a high complaint volume subtracts.
- Conciliation rate (c2) → If most complaints in conciliation resolve in the consumer’s favor, it adds; otherwise it subtracts.
- RPCA-registered adhesion contract (c14) → PROFECO reviewed and struck abusive clauses before inscription → adds.
- Irregularity flags → A shut-down project caps Compliance at 25; suspended subtracts 20 (see Red flags).
We only measure what open public data lets us verify (PROFECO + SEDETUS). Indicators that require private documents or gated lookups (SAT, INSEJUPY, notarial records) are not here — we prefer a short, honest framework over a long checklist with boxes that never fill.
Track Record and Performance · 35%
14 operational indicators. We combine what the developer reports with physical verification of delivered projects and warranty data.
- Continuous years operating under the same legal name
- Number of verifiable delivered projects (site visit or registry)
- Total units delivered vs promised
- On-time delivery rate (no delay > 60 days)
- Average delay across delayed projects
- Geographic diversification of the portfolio
- Project mix: residential, commercial, mixed-use
- Share of abandoned or cancelled projects
- Compliance with 5/3/1 warranties (structure/waterproofing/installations)
- Formal claims for structural defects
- Claims for non-conformance with specifications
- Documented unilateral changes to the project mid-construction
- Historical liquidity to cover payroll and subcontractors
- Active institutional financing capacity
Public Reputation · 25%
15 indicators weighted with Bayesian smoothing to resist low-volume manipulation, plus external sources that always carry weight even before Shield My Field has reviews.
- Verified reviews (with proof of purchase) on Shield My Field
- Bayesian-smoothed average rating
- Verified review volume (more volume = more weight)
- On-time delivery sub-rating in reviews
- Build quality sub-rating in reviews
- Customer service sub-rating in reviews
- Value-for-money sub-rating in reviews
- Recent catastrophic reviews (knockout if 3+ with under 2 stars)
- Google Business rating and volume
- Facebook page rating and volume
- Media sentiment in specialized press
- Mentions in buyer forums and Yucatán communities
- Recent reputational crisis (scandal, negative exposure)
- Developer responsiveness to reviews (transparency)
- Pattern vs isolated incident in similar complaints
Bayesian smoothing: why a single review does not determine your reputation
We apply Bayesian smoothing with prior mean 3.5 and smoothing constant C=5. The math behaves as if every developer started with C virtual neutral reviews. You need 10 or more verified reviews before reviews dominate the reputation calculation. A single 5-star review will not score 100, and a single 1-star review will not destroy it.
Industry standard. IMDB, Rotten Tomatoes, and most serious rating systems use it. Its purpose is to resist manipulation.
Irregular, suspended, or shut-down projects
When a Mexican authority officially publishes that a project is irregular, suspended, or shut down, we apply a published discount to the developer's Compliance score. The rule is transparent and auditable.
- Shut down → Compliance capped at 25/100. Total score drops to High Risk band.
- Suspended → Compliance reduced by 20 points (min 0).
- Irregular without shutdown → No automatic discount; appears as a visible red flag on the profile.
Evidence rules
- Every flag requires official folio, notice date, and public URL (gob.mx or other authority).
- The developer is notified by email and has a 7-day grace window before the flag becomes publicly visible.
- The developer's right of reply is always published alongside the flag.
- If the authority lifts the shutdown/suspension, the flag is marked "cleared" and the score is recalculated.

Four risk bands
The final Trust Score number maps to one of four bands to make it actionable. Bands are color-coded across the platform.
Spotless track record. Compliance in order, historically on-time delivery, positive verified reviews. Low risk.
Solid, with minor observations. One or two areas to watch but meets legal and delivery requirements. Recommended with due diligence.
Multiple yellow flags. Recurring delays, unresolved complaints, missing public evidence of a permit, or mixed reviews. Consider alternatives.
Significant red flags. PROFECO rulings against, encumbered properties, abandoned projects, or catastrophic reputation. We do not recommend purchase until resolved.
Per-project score (independent of the developer score)
Each individual development gets its own 0–100 score. Useful to compare projects from the same developer and identify differences between, say, a flagship tower and a satellite project. Four components:
- Project regulatory compliance (license, MIA, land-use): 30%
- Construction progress against the promised schedule: 25%
- Financial safety and investment vehicle (trust, escrow): 20%
- Developer backdrop (the developer current Trust Score): 25%
Update frequency
Scores are recalculated at least once a month. Material events (new PROFECO complaint, final ruling, project delivery, verified review) trigger an immediate recalculation.
Right of reply
Every developer can respond to individual reviews and dispute the score in writing. Replies are published next to the original review. Score disputes are resolved by PeninsuLawyers after reviewing new documentary evidence.
External audit
PeninsuLawyers acts as the independent legal auditor: approves the methodology, reviews each indicator annually, and signs off on per-developer executive reports.
What the Trust Score is NOT
Not a financial or delivery guarantee. Not a substitute for individualized legal advice. Changes over time as new data arrives. Does not measure design, location, or subjective preference — only verifiable compliance, performance, and reputation.
B2B services for developers
Developers can buy three optional services: portal subscription, lawyer audit by PeninsuLawyers, and sponsored placement. None of the three alters the Trust Score, which is computed solely with the public methodology above.
"Active profile" badge
Shown when the developer keeps an active monthly or yearly subscription (5,000 MXN/mo or 49,990 MXN/yr). Unlocks review + flag replies and profile edits. Cancelable.
"Lawyer-audited" badge
One-off 29,999 MXN. PeninsuLawyers reviews incorporation, permits, and PROFECO compliance. Verifies document authenticity — does NOT guarantee project quality or investment results.
Sponsored slot
14,990 MXN/month per state. Appears as a highlighted card ("Sponsored" label) on home and state search during the paid month. It is advertising — not a recommendation. The Trust Score is unaffected.
Brokers and property listings
Brokers and agencies publish third-party inventory and are excluded from the Trust Score and developer rankings — a listing receives no trust rating. When a listing is linked to an assessed development, the Trust Score shown is the project developer's, not the property's or the broker's. The "Featured" listing is paid advertising, not a recommendation. We do not verify individual listings.
