Know exactly what you are inheriting before you take over the lease.
When you assume a commercial lease — by assignment, business purchase, or sublease — you inherit it as-is. Upload the lease and get a due-diligence report on landlord consent and recapture, the liability you assume, the estoppel, CAM exposure, existing defaults, and surrender obligations — each tied to a quote from the document.

Assumed Lease (DD) Analysis
A representative assumed lease sample report — danger score 92/100, 8 red flags with verbatim evidence quotes, no signup needed.
What the assumed-lease analyzer checks
The review works through the consent, liability, verification, and condition issues that decide what you are really taking on when you inherit a lease.
Landlord consent & recapture
The consent standard (reasonable vs sole discretion), transfer fees and conditions, and any landlord recapture/termination right that can kill the deal.
Assignment vs sublease
Which structure you are using and what it means — privity of estate with the landlord vs depending on the original tenant.
Inherited liability & novation
What obligations you assume (including any pre-closing defaults), whether the seller stays liable, and whether you need a novation or release.
Estoppel certificate
The key diligence document — confirming current rent, the deposit actually held, defaults, options, and side agreements against the lease.
CAM & operating-expense exposure
Uncapped pass-throughs, a base-year reset on assignment, and the year-end true-up that can bill you for months before you took over.
Security deposit & guaranty
Whether the deposit transfers, and whether the landlord demands a new deposit or a personal guaranty as a condition of consent.
Remaining term & options
How much runway you inherit, renewal-notice deadlines, and whether options and ROFRs actually survive the assignment.
Existing defaults & surrender
Whether the lease is already in default and the inherited restoration ("make-good") and deferred-maintenance obligations.
Use, exclusives & co-tenancy
Whether the inherited use clause permits your business, plus exclusives, co-tenancy, and continuous-operation provisions.

Due Diligence on an Assumed Commercial Lease
When you take over someone else’s lease, you inherit their obligations as-is. Here is the order to investigate what you are stepping into before you close.
Lease Assignment vs Sublease: What You Inherit
Whether you take a lease by assignment or sublease decides who your landlord really is — and how exposed you are.
Landlord Consent & Recapture on Lease Assignment
Most commercial leases let the landlord block — or take back — the space when you try to take over. Read the consent and recapture clauses first.
Continuing Liability & Novation in Lease Assignments
An assignment can leave you fully liable for the whole lease — and a plain assignment usually does not release the seller. A novation is what actually shifts liability.
Estoppel Certificates in Lease Due Diligence
The estoppel certificate is how you verify the lease you are inheriting actually matches reality — get it before you close.
SNDA & Subordination When Assuming a Lease
If the landlord’s lender forecloses, an SNDA is what keeps your inherited lease alive — confirm one exists before you take over.
Inheriting CAM & Operating Expenses on an Assumed Lease
When you take over a lease, you take over its CAM math — including a year-end true-up that can bill you for costs run up before you arrived.
Security Deposit & Guaranty When Assuming a Lease
Taking over a lease can mean the landlord wants a fresh deposit and your personal guaranty — and the old deposit may not simply transfer.
Remaining Term & Renewal Options on an Assumed Lease
You are buying whatever term and options are left — confirm how much runway you have and whether the renewal rights actually transfer to you.
Inherited Defaults & Surrender Obligations on a Lease
When you take over a lease you can inherit its unpaid charges, its deferred maintenance, and the prior tenant’s obligation to restore the space at the end.
Use Clause, Exclusives & Co-Tenancy on an Assumed Lease
A lease can be a great deal and still be useless to you if its use clause does not permit the business you plan to run.

Frequently asked questions
What does it mean to assume a commercial lease?
It means taking over an existing lease — by assignment, as part of buying a business, or via sublease — so you step into the remaining term and its obligations. You generally inherit the lease as-is, including its rent, restrictions, and often its liabilities, which is why due diligence matters.
What documents does this cover?
The commercial lease you are taking over, plus assignment and assumption agreements, subleases, estoppel certificates, and SNDAs. Upload the lease itself for the core review; the analyzer flags what to verify in the related documents.
How is this different from a regular lease review?
A regular review helps you negotiate a lease you are signing fresh. This is due diligence on a lease you did not negotiate and will inherit as-is — so it focuses on consent, recapture, inherited liability, the estoppel, CAM true-ups, and existing defaults rather than on negotiating terms.
Is this legal advice?
No. This is general information and document-review prompts. Assignment, consent, and inherited-liability rules depend on the exact lease and your state — confirm specifics with a qualified attorney before you close.
