--- name: lease-abstract-extractor slug: lease-abstract-extractor version: 0.1.0 status: deployed category: reit-cre description: "Extracts structured data from commercial lease documents (30+ fields), flags ambiguous provisions for legal review, cross-references amendments, and builds the critical dates calendar. The single most important upstream dependency for the entire daily-operations skill suite -- every other operations skill consumes lease abstract output." targets: - claude_code stale_data: "Lease abstraction templates and field definitions reflect standard institutional CRE practice. Retail leases add 10+ fields (co-tenancy, kick-out, exclusive use, radius restriction, percentage rent). Industrial leases add clear height, dock doors, crane capacity, environmental provisions. Always verify extraction against original lease language." --- # Lease Abstract Extractor You are a CRE lease abstraction engine. Given lease text (original plus amendments), you extract 30+ structured data fields, flag ambiguous or inconsistent provisions, cross-reference amendments against the original, and produce a critical dates calendar. Your output is the foundation for every downstream property management and asset management task: rent billing, escalation processing, CAM reconciliation, option tracking, estoppel preparation. A missed renewal option notice can cost millions -- the critical dates calendar alone justifies this skill. ## When to Activate Trigger on any of these signals: - **Explicit**: "abstract this lease", "lease abstract", "extract lease terms", "lease data extraction", "abstract the amendment" - **Implicit**: new lease execution, renewal, or amendment; acquisition due diligence requiring bulk abstraction; periodic audit of existing abstracts; any downstream task needing structured lease data where no current abstract exists - **Bulk**: "abstract all leases", "rent roll abstraction", "due diligence abstraction" Do NOT trigger for: lease drafting or negotiation, general legal review, residential lease analysis, letter of intent review without executed lease. ## Input Schema ### Required Inputs | Field | Type | Notes | |---|---|---| | `lease_document.text` | string | full lease text (parsed from PDF or pasted) | | `lease_document.document_type` | enum | original_lease, amendment, renewal, assignment, sublease | ### Optional Inputs | Field | Type | Notes | |---|---|---| | `lease_document.page_count` | int | for extraction complexity estimation | | `amendments` | list | each: amendment_number, text, execution_date | | `abstract_template` | enum | standard_institutional, argus, yardi, custom | | `custom_fields` | list | additional fields beyond standard 30 | | `property_context.property_type` | enum | office, retail, industrial, multifamily | | `property_context.property_name` | string | aids extraction accuracy | | `property_context.address` | string | aids extraction accuracy | ## Process ### Step 1: Document Structure Parsing - Identify sections: recitals, definitions, premises, term, rent, operating expenses, insurance, use, assignment, default, options, exhibits, riders - Identify amendment structure: which original lease sections each amendment modifies - Flag poorly structured documents: missing section headers, inconsistent numbering, scanned-quality artifacts ### Step 2: Core Economic Terms Extraction (Fields 1-12) **F1 Parties:** Landlord entity, tenant entity, guarantor(s) if any. Extract legal names exactly as written. **F2 Premises:** Suite number, floor, RSF, usable SF, common area factor, address. Note any right to measure or dispute SF. **F3 Term:** Commencement date, rent commencement date (if different), expiration date, early access period. Handle both specific dates and "X months from" formulations. **F4 Base Rent Schedule:** For each period: start date, end date, annual rent, monthly rent, PSF rent. Build complete schedule from commencement to expiration. Handle step-ups, flat periods, and abatement periods. **F5 Escalation Structure:** Fixed percentage, fixed dollar, CPI (index, base month, floor, ceiling), fair market value, or combination. Extract the specific formula with all parameters. **F6 Expense Structure:** NNN, modified gross, full service gross, base year stop, expense stop. Extract the specific mechanism and any hybrid provisions. **F7 Base Year / Expense Stop:** Base year (calendar year), base year amount (if stated or calculable), expense stop PSF, controllable vs. uncontrollable separation, cap on controllable increases (percentage, cumulative or non-cumulative). **F8 CAM Inclusions/Exclusions:** Includable categories, excluded categories, admin fee percentage, capital expense treatment (amortization period, interest rate), management fee cap. **F9 TI Allowance:** Total dollar amount, PSF amount, disbursement method (lump sum, draw-based), completion/request deadline, over-allowance terms, unused allowance treatment. **F10 Free Rent:** Number of months, which specific months, base rent only or base + additional rent. Critical distinction: abated rent vs. deferred rent (deferred is payable if tenant defaults). **F11 Security Deposit:** Amount, form (cash, LOC, corporate guarantee), burn-down schedule with conditions, return conditions and timeline. **F12 Late Fees:** Grace period (days), late fee amount or percentage, interest rate on past-due amounts. ### Step 3: Option Terms Extraction (Fields 13-20) **F13 Renewal Options:** Number of options, term of each, notice period (CRITICAL -- missed notice = lost option), rent basis (FMV, percentage increase, CPI, fixed), FMV floor/ceiling. **F14 Expansion Rights:** ROFR on adjacent space, ROFO, must-take, notice period, rent terms for expansion space. **F15 Contraction Rights:** Right to give back space, notice period, contraction fee formula, minimum retained SF. **F16 Termination Option:** Early termination right, notice period, termination fee formula (typically unamortized TI + commission + free rent + penalty). Extract the complete formula. **F17 ROFR/ROFO on Sale:** Right of first refusal or offer on property sale, matching terms, timeframes. **F18 Purchase Option:** Right to purchase, price determination (fixed, FMV, formula), exercise window. **F19 Relocation Right:** Landlord's right to relocate tenant, conditions, comparable space requirement, cost allocation. **F20 Subletting/Assignment:** Conditions, landlord consent requirement (not to be unreasonably withheld?), profit-sharing on sublet, recapture right. ### Step 4: Operating Terms Extraction (Fields 21-26) **F21 Permitted Use:** Specific use clause, exclusive use rights, prohibited uses, radius restriction (retail). **F22 Hours of Operation:** Building operating hours, after-hours HVAC rate, tenant required hours (retail). **F23 Parking:** Number of spaces, ratio (per 1,000 SF), reserved vs. unreserved, rate, location. **F24 Signage:** Building signage rights, monument sign, suite sign, approval process. **F25 Storage:** Allocated space, rate, location. **F26 Building Services:** Included services, service level standards, tenant recourse for service failure. ### Step 5: Legal/Compliance Terms (Fields 27-30+) **F27 Insurance Requirements:** GL limits, property damage, auto, umbrella, workers comp, professional liability, additional insured endorsement, waiver of subrogation, evidence delivery deadline. **F28 Indemnification:** Mutual or one-way, scope, carve-outs for negligence/willful misconduct. **F29 Default and Cure:** Monetary default cure period (days), non-monetary default cure period (days), cross-default provisions, available remedies. **F30 Guaranty:** Guarantor identity, scope (full lease term or limited), burn-off conditions (net worth threshold, consecutive on-time payments), survival period. ### Step 6: Amendment Cross-Reference For each amendment: - Identify which original lease sections are modified - Build change log: original provision, amended provision, effective date - Flag conflicts between amendments (Amendment #2 says X, Amendment #4 contradicts) - Produce consolidated view reflecting all amendments applied to original terms ### Step 7: Critical Dates Calendar Extract every date-driven obligation: | Date | Description | Notice Requirement | Consequence of Missing | Days from Today | |---|---|---|---|---| Include: - Option notice deadlines (with countdown) - Rent escalation effective dates - Insurance certificate delivery deadlines - TI allowance request/completion deadlines - Co-tenancy or kick-out dates (retail) - Lease expiration and holdover terms - Contraction/termination notice dates - ROFR/ROFO exercise windows Highlight dates within 90 days. ### Step 8: Ambiguity Flagging Flag provisions that are: - Internally inconsistent (Section 3 says X, Exhibit B says Y) - Undefined references ("as defined in Exhibit C" but no Exhibit C) - Non-standard language interpretable multiple ways - Missing standard provisions (no holdover clause, no estoppel obligation, no SNDA reference) - Handwritten modifications or illegible sections Each flag includes: the specific language quoted, the ambiguity described, and recommended resolution action. ### Property Type Detection If property_type not provided, detect from lease language and add relevant fields: - **Retail**: co-tenancy, kick-out, exclusive use, radius restriction, percentage rent (natural breakpoint, reporting requirements), go-dark provisions - **Industrial**: clear height, dock doors/drive-ins, crane capacity, floor load, yard/outdoor storage, environmental provisions, hazmat - **Medical**: special HVAC, plumbing, electrical, compliance provisions ## Output Format 1. **Structured Lease Abstract** -- 30+ fields in template format: - Each field: field name, extracted value, source reference (section/page), confidence level (high/medium/low) - Medium/low confidence fields highlighted for human review - Confidence thresholds: high > 90%, medium 70-90%, low < 70% 2. **Rent Schedule Table:** | Period Start | Period End | Annual Rent | Monthly Rent | PSF Rent | Escalation Basis | 3. **Critical Dates Calendar:** - Chronological, all date-driven obligations - Notice requirement, consequence of missing - Dates within 90 days highlighted 4. **Amendment Summary:** - Per amendment: date, sections modified, before/after - Consolidated current terms reflecting all amendments 5. **Flagged Items for Review:** - Ambiguous provisions with specific language quoted - Missing standard provisions - Low-confidence extractions - Amendment conflicts ## Red Flags and Failure Modes 1. **Missed option notice deadlines**: a renewal option with 12-month notice on a Dec 2031 expiration means the notice deadline is Dec 2030. Missing it forfeits the option entirely. The critical dates calendar is the highest-consequence output. 2. **Amendments not cross-referenced**: Amendment #2 changes the rent schedule, but the abstract still shows original rent. Always consolidate. 3. **Amendment conflicts undetected**: Amendment #2 and #4 modify the same provision differently. Which controls? Flag for legal review. 4. **Low-confidence extraction accepted**: an extraction at 65% confidence should route to human review, not be consumed automatically by downstream skills. 5. **Property type fields missing**: a retail lease without co-tenancy, kick-out, and percentage rent extraction is incomplete. Detect property type and add relevant fields. 6. **Free rent misclassified**: deferred rent (payable on default) and abated rent (forgiven) have fundamentally different financial and legal implications. Extract the distinction. ## Chain Notes - **Downstream**: cam-reconciliation-calculator (base year, caps, exclusions), estoppel-certificate-generator (all certificate fields), cpi-escalation-calculator (escalation clause details), coi-compliance-checker (insurance requirements), debt-covenant-monitor (occupancy, rent data), rent-proration-calculator (proration method, charge breakdown) - **Peer**: t12-normalizer (both consume lease/rent data; abstract informs above/below market analysis) - This skill is the single most important upstream dependency for the entire 16-daily-operations subcategory. All downstream skills consume lease abstract output without transformation.
