RentFAX

RentFAX Methodology

Transparent, explainable, behavior-based methodology designed to make renting safer, fairer, and more accountable — without relying on protected characteristics or opaque scoring systems.

Guiding Principles

  • Fairness Before Prediction

    RentFAX methodology avoids protected classes entirely. We only analyze rental behavior, documented incidents, dispute outcomes, and identity integrity.

  • Identity Integrity First

    Fraud signals can dramatically change risk, so identity consistency and verification status influence how other factors are weighted.

  • Timelines Matter

    Behavior is evaluated in the context of time — short bursts of severe incidents differ from events spaced over many years.

  • Explainability

    Every insight served in RentFAX is tied to documented evidence. No “mystery scores,” and renters can view and dispute contributing items.

What Our Methodology Evaluates

1. Identity Integrity

We validate consistency across submitted data points:

  • Name, address, and DOB alignment
  • Phone and email reuse across incidents
  • Mismatched or recycled contact patterns
  • Document verification quality (if provided)

2. Incident History

We categorize incidents into weighted groups:

  • Non-payment or charge-offs
  • Property damage or vehicle damage
  • Behavioral incidents (aggression, policy violations)
  • Administrative issues (fraud attempts, false identity)
  • Positive resolutions (paid balances, successful appeals)

3. Fraud Signals

Proprietary fraud detection highlights patterns such as:

  • Duplicate identity markers across profiles
  • Impossible timelines across addresses
  • Known fraudulent contact data patterns
  • Conflicts between documents and reported identity

4. Behavioral Consistency

We evaluate patterns across verified companies:

  • Repeated late payments or disputes
  • Inconsistent communication or evasion
  • Resolution quality and renter cooperation
  • Positive trends such as dispute wins or successful rentals

Timeline Logic

Events in a renter’s history are not evaluated in isolation. The timeline engine reconstructs a chronological sequence of incidents, disputes, resolutions, and verification events.

  • Recent severe incidents weigh more heavily than older minor ones
  • Resolved disputes reduce risk weighting over time
  • Long periods with no incidents increase reliability signals
  • Fraud signals decay slowly, depending on severity

What We Do NOT Consider

RentFAX methodology avoids:

  • Race, ethnicity, national origin
  • Gender identity or orientation
  • Age (except when required for identity validation)
  • Income level unrelated to rental performance
  • Disability status or medical information
  • Immigration status

RentFAX evaluates **behavior, documentation, and verified outcomes**, not protected characteristics.
