Never Question a Decision

Complete transparency into every AI recommendation

Decision Breakdown

Every AI decision comes with plain-English explanation: "Approved because LTV 68% (below 70% threshold), credit score 720 (above 650 minimum), borrower has 5 completed flips."

  • Plain-English reasoning
  • Rule-by-rule breakdown
  • Factor weighting shown
  • Pass/fail for each criterion

Risk Flag Explanations

When AI flags a risk, it tells you why: "DSCR 1.15 is below preferred 1.25 threshold" or "ARV ratio 185% suggests aggressive valuation based on historical comp accuracy."

  • Specific risk identification
  • Threshold comparison
  • Historical context
  • Severity rating

Data Source Attribution

Shows exactly where each data point came from: "Credit score 720 from Experian report page 2, LTV calculated from appraisal dated 10/15/2024 showing $350K value."

  • Document source linking
  • Page number references
  • Extraction confidence scores
  • Date stamps

Model Confidence Scores

AI provides confidence level for each prediction: "Risk score 42 with 94% confidence" or "ARV estimate $385K with 78% confidence (limited comp data)."

  • Prediction confidence %
  • Data quality indicators
  • Model uncertainty flags
  • Manual review triggers

Factor Importance Ranking

Shows which factors mattered most: "LTV (40% weight), Credit Score (25%), Experience (20%), Liquidity (15%). LTV was the primary approval driver."

  • Weighted factor contribution
  • Primary decision drivers
  • Comparative influence
  • Sensitivity analysis

Complete Audit Trail

Every action logged: who uploaded documents, when AI ran analysis, which underwriter reviewed, override reasons, final decision timestamp.

  • Full activity timeline
  • User attribution
  • System vs. human actions
  • Timestamp precision

Regulatory Compliance Reports

One-click export of decision rationale in regulator-friendly format. Meets fair lending requirements, shows non-discriminatory decision criteria.

  • Compliance report generation
  • Fair lending documentation
  • Adverse action notices
  • Export to PDF/Excel

Human Override Tracking

When underwriters override AI, system logs reason: "Overridden by Sarah Johnson on 10/20/24 - Reason: Borrower provided additional liquidity proof post-AI analysis."

  • Override documentation
  • Reason code requirements
  • Manager approval workflow
  • Override pattern analysis

Decision Explanation Example

What underwriters actually see

Loan #2024-10452 - Decision: APPROVED

Auto-Approved

Why Explainability Matters

Trust, compliance, and better decisions

01

Underwriter Confidence

When AI shows its work, underwriters trust the recommendations. They can verify logic, spot errors, and learn from AI's reasoning to improve their own skills.

02

Regulatory Defense

Examiners ask "Why did you approve this loan?" You pull up full decision record showing non-discriminatory criteria, fair lending compliance, complete documentation.

03

Borrower Transparency

Declined borrowers get specific reasons: "Declined due to LTV 78% exceeding 75% maximum." Clear explanation prevents confusion and potential discrimination claims.

04

Model Improvement

When you see AI's reasoning, you can spot where it's wrong and provide feedback. "AI weighted this factor too heavily" helps retrain models for better accuracy.

Explainable AI – FAQ

How lenders, compliance, and investors use it

What is explainable AI in private real estate lending?

Explainable AI means every automated decision can be traced back to clear, numeric factors like LTV, DSCR, collateral quality, borrower experience, and liquidity. Instead of a black box score, you see exactly which rules fired, which thresholds were applied, and why a loan was approved, declined, or routed to manual review.

How does Mentyx make AI underwriting transparent for my team?

Each loan file includes a decision breakdown: plain-English summary, pass/fail view of key metrics, factor importance ranking, confidence scores, and links back to the original documents. Underwriters can override any decision with a required reason code, and the override becomes part of the permanent audit trail.

Does explainable AI help with regulators and investors?

Yes. Compliance teams can export regulator-friendly reports that show which factors were used, how policies were applied, and how adverse action reasons were determined. This supports fair lending, reduces discrimination risk, and gives capital providers confidence that your AI is aligned with your credit policy.
