Commercial Lease Analyzer
Analyze commercial leases (office, retail, industrial, warehouse) for hidden costs, unfavorable terms, and negotiation leverage. Use when reviewing a new lease, renegotiating a renewal, or comparing multiple lease options.
When to Use
- Signing a new commercial lease
- Lease renewal negotiation
- Comparing multiple lease proposals
- Auditing existing lease for cost reduction
- Subleasing or assignment analysis
What You Need from the User
- Lease type: Office, retail, industrial, warehouse, mixed-use
- Lease terms: Base rent, term length, renewal options
- Cost structure: NNN, modified gross, full-service gross
- Square footage: Usable vs rentable (load factor)
- Location/market: City, submarket (for comp analysis)
Analysis Framework
1. Cost Breakdown (True Occupancy Cost)
Base Rent ($/SF/yr)
+ CAM Charges (Common Area Maintenance)
+ Property Tax Pass-Through
+ Insurance Pass-Through
+ Utility Estimates
+ Parking Costs
+ Janitorial (if not included)
= Total Occupancy Cost ($/SF/yr)
÷ 12 = Monthly Cost
× Term = Total Lease Liability
2. Load Factor Analysis
Rentable SF ÷ Usable SF = Load Factor
Industry benchmarks:
- Class A Office: 1.15-1.20 (15-20% common area)
- Class B Office: 1.12-1.18
- Retail: 1.05-1.10
- Industrial: 1.02-1.05
Flag if load factor > benchmark. Every 1% = real money.
Example: 5,000 USF at 1.20 = paying for 6,000 RSF
At $30/SF = $30,000/yr for hallways and lobbies
3. Escalation Modeling
Project total cost over full term including:
- Fixed increases: 3% annual is standard. Flag >3.5%
- CPI-linked: Model at 2.5%, 4%, 6% scenarios
- Market reset: Compare to projected market rents
- CAM escalation caps: If uncapped, model 5-8% annual increases
Output a year-by-year cost table showing base rent, estimated CAM, total cost.
4. Critical Clause Review
Red Flags (flag immediately):
- Personal guarantee without sunset clause
- Demolition clause (landlord can terminate for redevelopment)
- Radius restriction >3 miles (retail)
- Continuous operation clause without co-tenancy protection
- Uncapped CAM with no audit rights
- Relocation clause (landlord can move you)
- No assignment/sublease rights
- Holdover rate >150% of final rent
Yellow Flags (negotiate):
- No rent abatement for construction delays
- No exclusive use clause (retail)
- HVAC maintenance fully on tenant
- No cap on controllable operating expenses
- Restoration clause requiring original condition
- No early termination option after year 3-5
- Insurance requirements above standard
Green (Standard/Favorable):
- TI allowance ($30-60/SF office, $15-30 retail)
- Free rent period (1 month per year of term)
- Right of first refusal on adjacent space
- Renewal option at fair market value
- CAM audit rights
- Assignment rights with reasonable consent
5. Negotiation Leverage Points
Based on market conditions, identify:
- Tenant's market (vacancy >15%): Push for higher TI, more free rent, lower escalations
- Landlord's market (vacancy <8%): Focus on caps, flexibility clauses, termination rights
- Balanced (8-15%): Standard negotiations, pick 3-4 priorities
Rank negotiation items by dollar impact over lease term.
6. Comparison Matrix (Multiple Options)
If comparing leases, output a side-by-side table:
| Factor | Option A | Option B | Option C |
|---|---|---|---|
| Effective Rent ($/SF) | |||
| Total 5-Year Cost | |||
| TI Allowance | |||
| Free Rent (months) | |||
| Escalation Type/Rate | |||
| Termination Option | |||
| Load Factor | |||
| Parking Ratio |
7. Financial Impact Summary
- Total lease liability (ASC 842 / IFRS 16)
- NPV of all lease payments (discount at 6-8%)
- Break-even occupancy cost per employee
- Cost per revenue dollar (if revenue data provided)
