Lease Analyzer
A lease is one of the most consequential contracts most people ever sign. It binds you for months or years, carries significant financial obligations, and is nearly impossible to exit early without cost. Most people sign them without fully understanding what's in them.

What we flag
Most state landlord-tenant laws require 24-hour advance notice before a landlord enters a rental unit — except in genuine emergencies. Leases that claim a right to enter "at any time" or with only "reasonable notice" (undefined) are a red flag. Once you sign, your ability to challenge this depends on whether your state's statutory protections override the lease language.
You signed a 12-month lease. You've been planning to move. But buried on page 6 is a clause that automatically renews the lease for another full year unless you provide written notice 60 days before the end date. Miss the window — even by a day — and you're on the hook for 12 more months. These clauses are legal and common. You just need to know they're there.
Vague security deposit clauses give landlords broad discretion to withhold your deposit. Language like "tenant shall be responsible for any damage" without defining normal wear-and-tear is a common source of disputes. The best leases clearly enumerate what constitutes damage versus ordinary use, and specify the timeline for returning the deposit.
Life changes. Jobs move. Families grow. Some leases hold you liable for every remaining month of rent if you leave early — even if the landlord re-rents the unit within a week. A reasonable early termination clause specifies a flat fee (1-2 months) or a duty to mitigate. "Liable for all remaining rent" language is one of the most consequential clauses in any residential lease.
Residential tenants have few maintenance obligations by law in most states — structural integrity, plumbing, heating, and habitability are the landlord's responsibility. Leases that transfer these obligations to tenants ("tenant responsible for all HVAC maintenance," "tenant responsible for pest control") may be unenforceable — but you need to know the clause is there to challenge it.
Commercial tenants often sign as a business entity to limit personal liability. But a personal guarantee clause makes you personally liable for the full lease term, regardless of what happens to the business. If the company folds in year two of a five-year lease, a personal guarantee means the landlord can come after your personal assets for the remaining three years.
Know the difference
Residential tenants have substantial legal protections in most states. Landlord-tenant law governs habitability standards, maintenance obligations, security deposit limits and timelines, and required notice periods for entry and termination.
The catch: clauses that violate local law may be technically unenforceable — but you need to know they're there to challenge them. A landlord who puts an illegal clause in a lease is counting on the tenant not knowing it's illegal.
We flag language that conflicts with standard tenant protections and explain what your state-level rights typically look like, so you can push back with confidence.
Commercial tenants have significantly fewer statutory protections. In commercial real estate, the assumption is that both parties are sophisticated actors capable of negotiating their own terms. That means almost everything is on the table.
Triple-net clauses shift property taxes, insurance, and maintenance costs onto the tenant. Personal guarantee clauses make the business owner personally liable. Co-tenancy clauses can trigger rent reductions or termination rights if anchor tenants leave.
Commercial leases are where the stakes are highest and legal review is most worth the money. We help you understand what you're looking at before that conversation.
