I'll kick off by pulling the application and the policy in parallel — then fetch the credit report once I have its reference.
Got the application and policy. Now fetching the bureau report.
All data in hand. Let me work through the numbers before committing.
Underwriting Analysis — Application L3 (Auto)
1. Score Band
| Metric | Value | Policy Threshold |
|---|---|---|
| Bureau score | 686 | Prime ≥ 720 / Near-Prime ≥ 660 / Subprime ≥ 600 |
| Band | Near-Prime | Min for auto = 600 pass |
2. DTI
- Monthly gross income: $64,000 ÷ 12 = $5,333.33
- Existing monthly obligations: $700
- New loan payment (60 months, 9.49% APR near-prime rate):
- r = 9.49% ÷ 12 = 0.79083%
- Payment = $22,000 × [0.007908 × (1.007908)⁶⁰] ÷ [(1.007908)⁶⁰ − 1] ≈ $462/mo
- Total monthly debt: $700 + $462 = $1,162
- DTI = $1,162 ÷ $5,333 = 21.8% vs. policy max 45% ✅
3. LTV
- LTV = $22,000 ÷ $21,000 = 104.8% vs. policy max 125% ✅
4. Credit File Assessment
| Factor | Detail | Flag? |
|---|---|---|
| Score | 686 (near-prime) | Clean pass |
| Utilization | 34% | Moderate, acceptable pass |
| Derogatory marks | None | pass |
| Public records | None | pass |
| Tradelines | 2 (card + student — both current) | pass |
| Oldest account | 72 months | pass |
| Thin file | No | pass |
| Inquiries (6 mo) | 2 | Minor; no concern pass |
| Employment | Salaried, 40 months | Stable pass |
No hard policy failures. All ratios comfortably within policy. → APPROVE at near-prime terms.
Now recording the decision:
The decision brief
Decision: APPROVED — Near-Prime Auto Loan
| Term | Detail |
|---|---|
| Loan amount | $22,000 |
| APR | 9.49% (near-prime rate) |
| Term | 60 months |
| Est. monthly payment | ~$462 |
| Score band | Near-Prime (686) |
| DTI (post-loan) | 21.8% (policy max: 45%) |
| LTV | 104.8% (policy max: 125%) |
Rationale
The application passes all hard policy tests cleanly. The applicant carries a 686 score (near-prime), a pristine credit history (no derogatives, no public records, all tradelines current), and stable salaried income that produces a DTI of only 21.8% after the new payment — less than half the 45% ceiling. The requested amount creates a 104.8% LTV on the 2022 Honda Civic, comfortably under the 125% cap. The near-prime APR of 9.49% is applied per policy. Confidence is high at 0.92.
