A business can look strong on paper — steady revenue, loyal customers, a clean set of books — and still be sitting on a lease that quietly undermines all of it. Because a lease governs the right to keep operating from a specific location, a bad one can turn a good business into a short-lived one. This article walks through the lease red flags most worth catching during due diligence, before you've committed to the deal.
None of these signs automatically kill a purchase. But each one changes the risk you're taking on, and each one is worth raising with your lawyer before you finalize price or terms.
Red Flags Table: What to Watch For and Why
| Red flag | Why it matters | What to do about it |
|---|---|---|
| Short remaining term with no renewal option | You may lose the location shortly after buying the business, with no guaranteed right to stay | Negotiate a lease extension or new lease as a condition of closing, or adjust price to reflect the risk |
| Assignment clause giving the landlord unrestricted discretion | The statutory "not unreasonably withheld" protection can be overridden by the lease's own wording | Confirm early whether the landlord is actually willing to consent before relying on this location |
| Personal guarantee required from the tenant | You (or your principals) may need to personally backstop the lease obligation, beyond the business itself | Negotiate the guarantee's scope and confirm whether the seller's existing guarantor will be released |
| Restrictive permitted-use clause | The lease may not actually allow everything the business currently does, or everything you plan to do | Compare the clause against actual and intended operations before relying on it |
| Vague or aggressive rent escalation terms | Operating costs could rise faster than the business's revenue can absorb | Model future rent against projected revenue before finalizing your offer |
| Landlord default or dispute history | An unresolved landlord issue could threaten the tenancy regardless of how well the business performs | Ask for and review any correspondence about defaults, arrears, or disputes |
| Co-tenancy or exclusivity conditions tied to other tenants | Rent reductions, exclusivity rights, or termination rights may depend on factors outside your control, like a neighbouring tenant staying open | Understand exactly what triggers gain or loss of these rights |
| Change-of-control clause that treats a share sale like an assignment | Buyers sometimes assume a share purchase avoids landlord consent — this type of clause defeats that assumption | Read the actual lease; don't assume a share deal automatically avoids landlord involvement |
Why These Details Get Missed
Lease red flags rarely show up in a quick skim. Assignment and change-of-control language is often buried in boilerplate sections that look identical from lease to lease — until they aren't. Rent escalation formulas can be described in a way that sounds routine but compounds meaningfully over several years. And a landlord dispute history often lives in email correspondence and side letters, not in the lease document itself, which is why asking directly (and reviewing landlord correspondence, not just the lease) matters.
How Red Flags Should Change Your Approach to the Deal
Finding a red flag doesn't necessarily mean walking away — it means adjusting how you approach the deal:
- Price. A lease with real risk attached is a reason to negotiate the purchase price down, not just a reason for concern.
- Conditions. Make resolving the issue — landlord confirmation, a lease amendment, an extended term — a condition of closing, rather than hoping it works out afterward.
- Structure. In some cases, a red flag in the lease shifts the calculus toward a different overall deal structure (for example, more caution around a share purchase if a change-of-control clause exists).
- Walking away. For a business genuinely dependent on its specific location, a lease that can't be fixed or worked around is sometimes a legitimate reason to pass on the deal entirely, regardless of how attractive the underlying business looks.
Frequently asked questions
Is a short lease term always a dealbreaker?
Not necessarily — it depends on how replaceable the location is for this particular business. A destination business with strong brand loyalty may survive a move; a business built entirely around foot traffic at one intersection may not. This is a business judgment as much as a legal one, but the legal review should surface the issue clearly either way.
What if the seller says the landlord relationship is "fine" and there's nothing to worry about?
Verbal reassurance isn't a substitute for reviewing the actual lease and any correspondence with the landlord. A good relationship today doesn't change what the lease document itself says will happen if that relationship changes.
Can a red flag in the lease be fixed before closing?
Sometimes. Landlords can agree to lease amendments, extensions, or clarified terms as part of the assignment process, particularly if approached early. Other red flags — like a fundamentally short remaining term with no willingness to renew — may not be fixable at all.
Does a personal guarantee requirement apply to every buyer?
It depends on the landlord and on the buyer's financial profile. A well-capitalized purchasing company with a strong track record may be able to negotiate out of a personal guarantee requirement that a newer buyer would have to accept.
