# Analyzing Lease Structures
Evaluates commercial lease terms by computing net effective rent, quantifying concession packages, and assessing tenant credit quality to support underwriting, acquisition, and portfolio management decisions.
## When To Use
- Underwriting a property acquisition and need to stress-test in-place lease economics
- Comparing competing tenant proposals on an apples-to-apples net effective rent basis
- Evaluating a REIT portfolio's weighted-average lease profile and rollover risk
- Assessing whether landlord concessions (TI, free rent, moving allowances) are market-appropriate
- Reviewing tenant creditworthiness before committing to long-term lease exposure
## Inputs To Gather
- **Lease abstracts or full lease documents** — base rent schedule, escalation clauses, expense structure (NNN, modified gross, full-service gross)
- **Concession details** — tenant improvement (TI) allowance, free rent periods, moving allowances, lease buyout payments
- **Tenant financials** — credit rating (Moody's/S&P if investment-grade), most recent annual revenue, net income, and balance sheet highlights; for private tenants, request financial statements or guarantor information
- **Market comps** — comparable lease transactions in the submarket (asking rent, achieved rent, concession packages, lease term)
- **Property-level data** — operating expenses per SF, cap rate assumptions, discount rate for NPV calculations
- **Lease term parameters** — commencement date, expiration, renewal options (fixed-rate vs. fair-market-value), termination rights, co-tenancy clauses
## Workflow
1. **Classify the lease structure**
- Identify expense type: NNN, modified gross, or full-service gross
- Map escalation mechanism: fixed annual bumps, CPI-linked, percentage rent, or fair-market resets
- Note any unusual provisions: co-tenancy kick-outs, go-dark clauses, exclusive-use restrictions, ROFO/ROFR on adjacent space
2. **Calculate net effective rent (NER)**
- Compute total undiscounted rent over the lease term including all escalations
- Subtract landlord concessions: TI allowance, free rent (valued at face rent for those months), moving allowances
- Divide by total lease months for a per-month NER, then annualize per SF
- For a present-value approach, discount cash flows at the landlord's cost of capital or market discount rate [VERIFY discount rate assumption with client/underwriting team]
3. **Analyze the concession package**
- Express TI as $/SF and compare to submarket averages
- Convert free rent to an equivalent rent reduction per SF per year over the term
- Calculate the landlord's total concession cost as a percentage of gross lease value
- Flag concessions that exceed market norms by more than 15–20% for further diligence
4. **Assess tenant credit quality**
- Investment-grade tenants (BBB-/Baa3 or above): note rating, outlook, and sector
- Sub-investment-grade or unrated tenants: review guarantor strength, security deposit or letter of credit terms, and lease guaranty structure
- Assign an internal credit tier (strong / acceptable / watch / substandard) based on financial metrics: debt-to-EBITDA, interest coverage ratio, and liquidity position [VERIFY internal credit-tier definitions per firm policy]
- For percentage-rent leases, evaluate tenant sales performance and trend trajectory
5. **Benchmark against market**
- Compare NER to submarket comps on a per-SF basis, adjusting for floor level, vintage, and amenity package
- Assess whether escalation structure keeps pace with projected market rent growth
- Identify mark-to-market exposure: leases significantly above or below market at expiration
6. **Compile risk factors**
- Rollover concentration: flag years where >15% of portfolio NRA or revenue rolls
- Tenant concentration: single-tenant exposure exceeding 10% of portfolio revenue
- Lease duration: weighted-average lease term (WALT) relative to debt maturity
- Early termination or contraction option exposure
## Output
Produce a structured analysis report containing:
- **Lease summary table** — tenant name, suite, SF, lease type, term, base rent/SF, escalation structure, NER/SF
- **Net effective rent calculation** — step-by-step buildup showing gross rent, concession deductions, and resulting NER (both undiscounted and PV-adjusted)
- **Concession benchmarking** — TI $/SF, free rent months, and total concession cost vs. market comps
- **Tenant credit snapshot** — rating/tier, key financial ratios, guaranty structure, and any watch-list flags
- **Risk summary** — rollover schedule, mark-to-market exposure, tenant concentration, and any non-standard lease provisions requiring attention
- **Recommendation** — clear statement on whether lease terms are at-market, above-market, or below-market, with suggested negotiation points or underwriting adjustments
## Quality Checks
- Verify that NER calculation accounts for all concession types, not just free rent
- Confirm escalation math ties to lease language (compounding vs. simple annual increases)
- Ensure expense stop or base-year assumptions are correctly reflected in NNN-equivalent comparisons
- Cross-check tenant credit data against the most recent available filings [VERIFY filing date]
- Validate that market comps are from the same submarket and asset class (office vs. industrial vs. retail)
- Confirm discount rate used for PV calculations aligns with property type and risk profile
- Flag any lease provisions that could affect NOI stability (kick-out clauses, co-tenancy triggers) even if not yet exercisable
