Short answer

What you should know before deciding

Before signing, confirm that the person is who they say they are, that the documents are consistent, that the financial capacity is supported and that the authorized references provide verifiable facts. The goal is not to find a ‘risk-free’ person, but to identify inconsistencies and resolve them before handing over possession.

01

Work sequence

Identity → consent → documents → capacity → references → relevant sources → clarifications → report.

The sequence avoids opening indiscriminate searches: each step must answer a question, produce evidence and leave a verifiable conclusion.

  1. 01
    Define the rent, property, and term.

    Define in writing the objective, scope and criteria that will be used to decide.

  2. 02
    Invite the applicant to submit their own data and files directly.

    Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.

  3. 03
    Validate identity, address, and supporting financial documents.

    Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.

  4. 04
    Check authorized references and relevant sources.

    Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.

  5. 05
    Document inconsistencies and allow the applicant to clarify them.

    Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.

  6. 06
    Decide using the report and contract, not an automated score.

    Conclude with confirmed facts, open items, limitations, and actions; avoid an opaque score.

Practical application

What to check and what to ask

Useful documents or evidence

  • Current official identification and CURP or RFC when relevant.
  • Proof of recent address and verifiable contact information.
  • Proof of income or activity for the last three months, according to the work profile.
  • Authorized reference details and the guarantor's email address so they can submit their case file directly.

Control questions

  • Are the name, address and signature consistent between documents?
  • Is the documented income reasonably proportionate to the rent?
  • Can the stated occupation and tenure be confirmed?
  • Are there differences that the person should clarify with additional documents?

Frequent errors

  • Accept cropped screenshots that do not show the issuer, period, or account holder.
  • Search only by name and attribute records belonging to namesakes.
  • Request sensitive data that is not related to the rental.
  • Convert a correctable inconsistency into an automatic refusal.

Scope and limits of this information

This content is educational and does not constitute legal advice for a specific case. A match does not confirm identity; a lawsuit is not equivalent to a sentence; a publication must be read in its state and date; The absence of findings only describes the sources reviewed and does not guarantee absence of risk.

Availability, coverage and updating of records vary. Before making a material decision, allow clarification, preserve evidence and request specialized advice when the result depends on a legal, fiscal, registry or contractual interpretation.
