What the lease analyzer checks
The review works through the clauses that decide what a lease really costs a tenant — quantified in real dollars wherever the lease gives the numbers.
Personal guarantee terms
Whether you are personally on the hook, how long the guaranty lasts, and whether there is any good-guy clause or burn-off that limits your exposure.
CAM & operating-expense pass-throughs
How operating expenses, CAM, taxes, and insurance are passed through — admin fees, base-year gaming, uncapped increases, and gross-up clauses that inflate your share.
Repairs & maintenance
Who pays for the roof, structure, and HVAC, and whether costly capital repairs are quietly shifted onto the tenant.
Assignment, sublease & change of control
Whether you can assign or sublet, the landlord’s consent standard, recapture rights, and whether a change in your ownership counts as a prohibited transfer.
Default & landlord remedies
Cure periods, acceleration of rent, landlord self-help, and how fast a missed payment can escalate.
Insurance & indemnity
Required coverage, waiver of subrogation, and one-sided indemnities that make you cover the landlord’s own negligence.
Relocation, demolition & casualty
Landlord rights to relocate or demolish, and what happens to your rent and lease if the premises are damaged or condemned.
Use, exclusive & radius clauses
Whether your permitted use is too narrow, whether you get exclusivity, and any radius restriction limiting where else you can operate.
Rent math & critical dates
Base rent, rent per square foot, escalations, security deposit, and base year — plus the commencement, expiration, and renewal-option notice deadline you cannot afford to miss.

Frequently asked questions
What is the most expensive trap in a commercial lease?
Usually the operating-expense / CAM structure combined with a personal guaranty. Uncapped pass-throughs, base-year gaming, and admin fees can add up to far more than the base rent over a term — and a personal guaranty puts your own assets behind it.
What is a renewal-option notice deadline?
Many leases require written notice months before expiration to exercise a renewal option. Miss it and you can lose the option entirely. The analyzer surfaces this date specifically because tenants miss it most.
Does it work for retail, office, industrial, and restaurant leases?
Yes. The analyzer adapts to the lease type and the issues that matter for it. See the industry guides for restaurant, retail, office, medical, and warehouse specifics.
Is this legal advice?
No. This is general information and document-review prompts. Lease enforcement and landlord-tenant rules vary by state — confirm specifics with a qualified attorney.
