# Skill: Draft Due Diligence Summary Memorandum for Residential Transition Loan ABS Transaction

## 1. Subject-matter triage (only if applicable)

- Use this skill when the input consists of diligence reports, stratifications, loan tapes, servicing materials, legal opinions, and open-item trackers for a residential transition loan securitization.
- Treat the memorandum as an advisory synthesis, not a data dump: the reader needs issue selection, legal consequence, and actionability.
- If the source set contains multiple loans, counterparties, states, or diligence samples, enumerate the relevant items before analysis and avoid collapsing them into one generic discussion.

## 2. Failure modes the skill is correcting

- Summarizing diligence findings without stating the legal consequence of each material issue.
- Describing defects in isolation rather than tying them to enforcement, eligibility, disclosure, or transaction risk.
- Treating concentration analysis as a pure credit exercise and omitting the disclosure dimension for the offering materials.
- Omitting a clear priority structure for unresolved items and leaving the deal team without sequencing guidance.
- Failing to connect diligence findings to the affected loan, document, or portfolio segment.
- Presenting conclusions without a stated legal authority or governing rule.
- Ending with diagnosis only, without an action-oriented recommendation.

## 3. Legal frameworks / domain conventions that apply

- Residential transition loans are short-term bridge loans secured by real property in transition; diligence commonly focuses on borrower authority, collateral coverage, insurance, licensing, construction completion, sanctions, and servicing controls.
- If an entity borrower is suspended, dissolved, or otherwise limited, analyze capacity under the applicable entity statute and the effect on contract performance and enforcement.
- Flood-zone issues should be analyzed under the applicable federal flood insurance requirements and the related securitization or regulatory consequence.
- Broker-origination issues should be analyzed under the applicable state mortgage-broker licensing law, including enforceability and rescission exposure where relevant.
- Hazard insurance and mortgagee naming issues should be tested against the policy terms and the lender-protection function of mortgagee or loss-payee status.
- Sanctions screening issues should be tied to the applicable sanctions regime and the resulting compliance, enforcement, and transaction-risk exposure.
- Geographic concentration is both a portfolio risk and a disclosure issue; identify the concentration and note any disclosure implication for the offering materials.
- Single-obligor concentration should be treated separately from geographic concentration because it is issuer- or asset-specific rather than regional.
- Maturity, extension, and payoff-date discrepancies should be framed in relation to cash-flow modeling, weighted average life, and transaction timing.
- Servicer-related discussion should cover operational capability, controls, and the backup servicing arrangement.

## 4. Analytical scaffolds

1. Open with a transaction overview that identifies the asset class, diligence sources reviewed, and the purpose of the memorandum.
2. State the scope and methodology by listing the sampled loans, the diligence reports reviewed, and the data cut used for the analysis.
3. For each material loan-level issue, identify the loan, state the defect, cite the governing authority or control standard, explain why the issue matters, and recommend a cure, waiver, exclusion, or further review.
4. When there is more than one loan-level issue, assign a consistent issue reference and analyze each issue in a separate row or subsection.
5. For suspended-entity problems, connect borrower capacity to the relevant state entity-law framework and explain whether the issue affects enforceability or performance.
6. For flood-related deficiencies, identify the applicable federal requirement and explain the effect on eligibility, insurability, or investor exposure.
7. For unlicensed broker origination, identify the applicable licensing framework and explain the resulting enforceability, rescission, or regulatory risk.
8. For missing or defective guarantees, explain the credit and enforcement consequence in relation to the loan balance or other transaction size reference in the sources.
9. For insurance naming errors, explain how the defect affects recovery proceeds after a casualty or loss event.
10. For sanctions concerns, state the governing sanctions authority and the regulatory consequence of the issue.
11. For maturity-date discrepancies, tie the issue to cash-flow modeling, amortization assumptions, and weighted average life calculations.
12. For geographic concentration, review the stratification data, identify the leading states, and state the concentration and disclosure implications without hard-coding transaction-specific percentages.
13. For single-obligor concentration, identify the largest exposure and state the event-risk consequence relative to the pool.
14. For servicer assessment, summarize operational capability, exception management, and any backup servicing arrangement.
15. Track unresolved matters in a prioritized open-items list with a clear severity scale defined once and applied uniformly.
16. End with recommended next steps that assign responsibility and timing.

## 5. Vertical / structural / temporal relationships (only if applicable)

- Distinguish loan-level, borrower-level, collateral-level, servicing-level, and portfolio-level issues; do not mix them in one analysis block.
- Keep the chain of analysis vertical: source fact, governing rule, legal consequence, transaction consequence, then action.
- Where timing matters, identify whether the issue is pre-closing, closing-condition, post-closing, or surveillance follow-up.
- If an issue depends on another document or schedule, cross-reference the interacting source in the memorandum rather than restating the same fact twice.
- When discussing concentrations or other multi-item data, present the ranking first and then the implications.

## 6. Output structure conventions

- Write the memorandum in a conventional deal-team format with a short executive framing section followed by scope, collateral findings, issue analysis, servicing, concentration, open items, and recommendations.
- Use clear headings and consistent issue numbering for material findings.
- Define an ordinal severity scale once at the outset and apply it uniformly to each open item and material issue.
- For each issue row or subsection, include: the affected loan or portfolio segment, the issue description, the legal or operational analysis, the consequence, and the recommended disposition.
- Include a table for concentration analysis and a separate table for unresolved items.
- Where the source materials identify legal authorities, cite them by name and section or other controlling citation form in the discussion.
- Keep the memorandum concise but complete; do not merely summarize the diligence reports—translate them into deal-relevant conclusions.
- End with a Recommended Actions block that uses imperative verbs, assigns the responsible role, and includes a timing anchor tied to the transaction milestones or regulatory deadlines.
