The lease allocates expenses
A net lease assigns specified property expenses to the tenant in addition to base rent. A triple-net arrangement generally covers property taxes, insurance and maintenance, but the contract determines roof, structure, casualty, environmental and capital obligations. Net lease is a contract structure used across property types, not simply a synonym for retail. A landlord still carries corporate overhead, financing obligations and the consequences of a tenant failing to perform. Read contractual exceptions before assuming an expense has disappeared.
Separate the tenant from the building
Two questions belong on different lines of an underwriting worksheet: can the tenant pay, and what could the property earn with another tenant? A strong parent name does not establish that the parent guarantees the lease. Review the legal obligor, guarantees, rent concentration and unit-level disclosure where available. A specialized building can require substantial conversion spending after a default. Portfolio occupancy may remain high while a small cluster of troubled tenants consumes disproportionate management time and capital.
Competing views on long leases
Long contracts can provide visibility and reduce near-term leasing work. The opposing view is that fixed annual escalators may lag inflation while financing costs reset more quickly. Inflation-linked provisions also may have caps, floors or delayed adjustments. Acquisition growth can create value when returns exceed the full cost of funding; it can dilute owners when equity issuance, debt costs and transaction expenses overwhelm the apparent property yield. Growth in total rent is therefore less informative than sustainable cash flow per share.
Read the reconciliation and maturity tables
Review rent collection, lease expirations, tenant industries, geographic concentration and debt maturities together. Distinguish contractual rent from straight-line accounting rent and compare cash rent growth with reported revenue growth. AFFO is not standardized; examine the issuer's reconciliation and recurring expenditure assumptions instead of comparing labels alone. A long weighted-average lease term is only an average: concentrated expirations or a large tenant failure can matter more than that headline. Issuer presentations should be cross-checked against annual-report risk factors and contractual disclosures.
Hypothetical worked example
Assume a property costs $10 million and produces $650,000 of annual rent, with the tenant paying the specified property expenses. The initial rent yield is $650,000 / $10 million = 6.5%. A 1.5% escalator adds $9,750 next year. If $5 million of debt refinances two percentage points higher, annual interest rises $100,000. This simplified comparison excludes other income, overhead, hedges and capital spending; the escalation alone does not offset the financing change.
A common mistake
Do not treat triple-net as a guarantee of zero landlord spending or equate a contractual property yield with the shareholder's return.
What to check in the disclosures
- Identify the actual tenant and guarantee.
- Read expense and capital-work exceptions.
- Compare escalators with refinancing exposure.
- Check AFFO adjustments and per-share growth.
