## When to Activate

Trigger on any of the following:
- "Lease amendment" or "draft an amendment"
- "Blend and extend" or "rent restructuring"
- "Expansion option" or "contraction option"
- "Renewal option" or "ROFR" or "ROFO"
- "Build-to-suit" or "BTS proposal"
- "Lease template" or "update the form lease"
- "Assignment" or "subletting consent"
- "Use change" or "permitted use"
- "Rent deferral" or "rent abatement"
- Any mention of lease modifications, option exercise, or tenant expansion

## Process

### Step 1: Amendment Drafting

1. **Scenario Classification**: Identify the amendment type and applicable template from the reference library.
2. **Economic Analysis**: Model the financial impact of the amendment on landlord's position:
   - NPV of current lease vs. amended lease
   - Impact on WALT and rollover schedule
   - Impact on property valuation (cap rate applied to new NOI)
   - Comparison to re-leasing economics (vacancy, downtime, TI, commissions)
3. **Provision Drafting**: Draft amendment provisions using standard language with:
   - Recitals identifying original lease and all prior amendments
   - Clear effective date and amendment numbering
   - Specific modifications to each affected section
   - Confirmation that all other terms remain unchanged
   - Signature blocks for all parties (including guarantors if applicable)
4. **Landlord Protection Review**: Verify the amendment includes:
   - No release of guarantor (unless intentional)
   - Updated estoppel representations
   - Reaffirmation of all other lease obligations
   - Updated insurance requirements if scope changes
   - Preservation of existing default/cure rights
5. **Negotiation Strategy**: Identify likely tenant pushback points and prepare landlord's response with fallback positions.

### Step 2: Standard Lease Template Refresh

1. **Market Scan**: Review recent lease transactions in portfolio and market for emerging terms, non-standard provisions, and tenant counsel pushback patterns.
2. **Legal Update**: Identify changes in landlord-tenant law, building codes, ADA requirements, environmental regulations, and data privacy that affect lease provisions.
3. **Operational Feedback**: Collect input from property management on provisions causing operational issues (CAM definitions, after-hours HVAC, signage rights, storage).
4. **Provision Update**: Revise specific provisions with tracked changes and counsel review notes. Priority areas:
   - Force majeure (post-COVID updates)
   - Assignment/subletting (co-working, desk-sharing)
   - Permitted use (flexibility vs. exclusivity conflicts)
   - Sustainability/ESG provisions (green lease clauses)
   - Technology infrastructure (EV charging, 5G, fiber)
5. **Version Control**: Maintain version history, summary of changes, and approval workflow.

### Step 3: Expansion/Contraction/Renewal Option Analysis

1. **Option Valuation**: Calculate the economic value of the option to the tenant and cost to the landlord:
   - **Expansion**: Value = (Market Rent - Strike Price) x SF x Remaining Term, discounted
   - **Contraction**: Cost = Amortized TI + Leasing Commission + Vacancy Cost during re-lease
   - **Renewal**: Value = Avoided transaction costs (broker commission, TI, downtime) vs. marking to market
2. **Exercise Probability**: Estimate likelihood of exercise based on:
   - In-the-money status (strike vs. market)
   - Tenant growth trajectory
   - Market alternatives for tenant
   - Space utilization trends
3. **Landlord Flexibility Cost**: Quantify the constraint on landlord's ability to:
   - Lease contiguous space to other tenants
   - Reposition or redevelop the space
   - Negotiate with competing prospects
4. **Recommendation**: Accept, reject, or counter-propose option terms with financial justification.

### Step 4: Build-to-Suit Evaluation

1. **Credit Analysis**: Evaluate tenant credit quality. Investment-grade tenants justify lower cap rates and longer amortization. Sub-IG requires credit enhancement (larger security deposit, letter of credit, guaranty).
2. **Cost Validation**: Verify construction cost estimate against market benchmarks:
   - Hard costs per SF by building type and finish level
   - Soft costs (A&E, permits, financing) typically 20-30% of hard costs
   - Developer fee (3-5% of total development cost)
   - Contingency (5-10%)
3. **Return Analysis**:
   - Development yield: Stabilized NOI / Total Development Cost (target: 150-250 bps above market cap rate)
   - Spread to cap rate: Development yield - exit cap rate (target: positive spread)
   - IRR over hold period (target: 8-12% unlevered for BTS)
4. **Lease Term Adequacy**: Verify lease term covers full amortization of TI and development costs. Minimum: 10 years for significant BTS. Preferred: 15+ years.
5. **Residual Value Assessment**: What is the property worth at lease expiration? Consider: location, building flexibility, market trends, obsolescence risk.

## Red Flags & Failure Modes

1. **Blend-and-extend below market**: Never agree to a blended rate that produces an amendment-term rent below market. The blend should produce a rate at or above market for the extension period, even if the near-term rate is reduced. Run the NPV both ways.
2. **Contraction option without adequate fee**: The contraction fee must cover landlord's unamortized TI, leasing commission, and expected vacancy/downtime cost. Typical fee: 6-12 months of rent for the given-back space.
3. **Expansion option on below-market space**: If the expansion option strike price was set years ago and is now well below market, the option may be extremely valuable to the tenant. Negotiate carefully -- the option is a contractual right.
4. **Guarantor release during amendment**: Tenants will try to release guarantors during amendment negotiations. Never agree unless receiving substantial additional consideration (longer term, higher rent, larger deposit).
5. **Vague fair market rent definitions**: Renewal options with "fair market rent" must define: who determines it (landlord, 3 appraisers, baseball arbitration), what is included/excluded (TI, commissions, concessions), and the reference date. Vague FMR definitions lead to disputes.
6. **Assignment/subletting without recapture right**: Always include landlord's recapture right (right to terminate the lease and take back the space) as an alternative to consenting to assignment/subletting. This prevents the tenant from profiting from a below-market lease.
7. **BTS for non-credit tenant without credit enhancement**: Never build to suit for a sub-investment-grade tenant without a substantial security deposit (12+ months), personal guaranty, or letter of credit covering remaining lease obligation.
8. **Exclusive use conflicts**: When drafting amendments that change permitted use, always check for exclusive use clauses in other tenants' leases. A use change that violates another tenant's exclusive can trigger liability.
9. **Co-tenancy triggered by contraction**: If a tenant's contraction reduces their footprint below a co-tenancy threshold for another tenant, it can trigger co-tenancy remedies (reduced rent, termination right) for that other tenant.
10. **Missing subordination, non-disturbance, and attornment (SNDA)**: Any new or materially amended lease should include SNDA provisions or a separate SNDA agreement, especially if the property is encumbered by a mortgage.

## Chain Notes

- **Upstream**: Receives lease data from `lease-abstract-extractor`, market rent data from `comp-snapshot` and `rent-optimization-planner`, tenant credit signals from `tenant-retention-engine`.
- **Downstream**: Feeds `lease-compliance-auditor` (updated lease terms for compliance monitoring), `estoppel-certificate-generator` (amended lease terms for estoppel accuracy), `rent-roll-analyzer` (updated rent roll after amendments).
- **Parallel**: Coordinates with `leasing-strategy-marketing-planner` for marketing and TI cost context, `cam-reconciliation-calculator` for CAM clause updates in amendments.
- **Data sources**: Lease files, rent roll, market comp databases (CoStar, CompStak), AIA lease form library.
- **Frequency**: Amendment drafting is ad-hoc (as negotiations arise). Template refresh is annual. Option analysis is ad-hoc (triggered by notice periods or tenant requests). BTS evaluation is project-specific.
