10 LOI Mistakes That Cost Landlords Thousands

Why LOI Mistakes Hit Landlords Hardest

Landlords typically draft the initial LOI, which creates a false sense of security. Because you wrote it, you assume it protects you. In reality, the LOI you drafted may contain gaps, weak language, and missing provisions that expose you to significant financial risk over the life of the lease.

The stakes are high. A single overlooked provision can cost $15,000 to $50,000 or more over a 10-year lease term. Multiply that across a portfolio of 20 or 30 tenants, and the cumulative impact of sloppy LOIs can reach into the hundreds of thousands.

Here are the 10 most common LOI mistakes we see landlords make, along with the specific dollar impact and the fix for each one. For a complete list of what every LOI should include, see the LOI provisions checklist.

Mistake 1: Missing Holdover Clause

The Problem

The LOI says nothing about what happens when the tenant remains in the space after the lease expires. Without a holdover provision in the LOI, the landlord's attorney may include one in the lease, but by then the tenant's counsel will push back hard. If the lease is ultimately silent on holdover, most states default to a month-to-month tenancy at the existing rent.

The Financial Impact

Suppose a tenant is paying $28 per square foot on a 4,000-square-foot space. The lease expires, and the landlord has a new tenant ready to move in at $34 per square foot, but the current tenant does not vacate. Without a holdover penalty, the existing tenant stays at $28 per square foot while the landlord loses $24,000 per year in the rent differential. If the holdover drags on for six months, that is $12,000 in lost revenue, plus potential damages owed to the incoming tenant whose move-in date keeps slipping.

The Fix

Include holdover language in the LOI that specifies rent at 150% of the then-current base rent for the first 60 days and 200% thereafter. State that holdover tenancy is on a month-to-month basis, terminable with 30 days notice from the landlord. This creates real financial incentive for the tenant to vacate on time.

Mistake 2: Weak Security Deposit

The Problem

The LOI specifies a security deposit of one month's base rent for a local tenant with no established operating history. One month of base rent provides almost no meaningful protection if the tenant defaults.

The Financial Impact

A local tenant leases 3,000 square feet at $26 per square foot NNN with NNN charges of $9 per square foot. The monthly gross occupancy cost is approximately $8,750. A one-month security deposit covers $6,500 in base rent. If the tenant defaults, the landlord faces two to four months of lost rent during the eviction process ($26,000 to $52,000), plus $5,000 to $15,000 in legal fees and make-ready costs to re-lease the space. A $6,500 deposit barely covers a fraction of that exposure.

The Fix

Require two months of base rent plus NNN for local tenants and new entities. For tenants with thin balance sheets, consider requiring three months. Structure the deposit with a burn-down provision that reduces it after 36 months of on-time payment. For more detail on structuring deposits effectively, see our security deposit negotiation guide.

Mistake 3: No Continuous Operation Requirement

The Problem

The LOI requires the tenant to pay rent but says nothing about actually operating the business. The tenant opens for six months, decides the location is underperforming, and "goes dark," continuing to pay rent on an empty storefront while operating from a different location.

The Financial Impact

A dark storefront in a multi-tenant retail center does more than lose one tenant's foot traffic contribution. Adjacent tenants see customer counts drop, percentage rent from other tenants declines, and the center's overall appeal deteriorates. In a 40,000-square-foot strip center, one dark 5,000-square-foot storefront can reduce foot traffic by 10% to 20%, which translates to $30,000 to $75,000 in lost percentage rent from other tenants annually. The property's value at a 7% cap rate drops by $430,000 to $1,070,000.

The Fix

Include a continuous operation clause in the LOI requiring the tenant to operate during standard business hours throughout the lease term. Specify that failure to operate continuously for more than 30 consecutive days constitutes a default. For anchor tenants, tie the continuous operation requirement to co-tenancy clauses so smaller tenants cannot use the dark store as grounds for rent reduction.

Mistake 4: Vague CAM Language

The Problem

The LOI states that the tenant will pay "their pro rata share of CAM charges" without defining what is included, what is excluded, or whether there is an annual cap. This gives the tenant's attorney room to negotiate narrow CAM definitions in the lease that exclude significant expense categories.

The Financial Impact

A landlord owns a 60,000-square-foot retail center with annual operating expenses of $480,000, or $8 per square foot. The LOI for a 5,000-square-foot tenant says "pro rata CAM." During lease negotiation, the tenant's attorney excludes capital expenditures, management fees above 3%, and reserves. The tenant's actual CAM obligation drops from $8 per square foot to $5.25 per square foot. That is $13,750 per year the landlord absorbs, or $137,500 over a 10-year lease. Across five tenants with similar lease terms, the landlord is underwater by nearly $70,000 annually on operating expenses.

The Fix

Specify in the LOI that CAM charges include all operating expenses, management fees (typically 3% to 5% of gross revenue), capital expenditure reserves, and insurance. If you are willing to offer a CAM cap, state the specific cap percentage, such as a 5% annual increase over the base year. For a deeper dive into structuring CAM provisions, see CAM Clauses in LOIs.

Mistake 5: Missing Assignment Consent Requirement

The Problem

The LOI does not address whether the tenant can assign the lease or sublease the space. Without this provision established at the LOI stage, the tenant's attorney will push for broad assignment rights in the lease, arguing that the LOI's silence indicates the landlord did not consider it a material term.

The Financial Impact

A creditworthy regional retailer signs a 10-year lease for 6,000 square feet at $30 per square foot. Three years in, the retailer assigns the lease to a startup concept with no operating history and minimal capitalization. The startup defaults 18 months later. The landlord now has a vacant space, lost the original credit tenant, and has no recourse against the assignor because the lease allowed assignment without restriction. The cost: six months of vacancy at $15,000 per month ($90,000), plus $20,000 in legal and re-leasing costs.

The Fix

State in the LOI that any assignment or sublease requires the landlord's prior written consent, which shall not be unreasonably withheld. Include the landlord's right to approve the assignee's financial qualifications, business concept, and intended use. Also include a recapture right so the landlord can terminate the lease and take the space back if the tenant seeks to assign.

Mistake 6: No Personal Guaranty for Local Tenants

The Problem

A local tenant forms a single-purpose LLC to sign the lease. The LLC has no assets beyond the lease itself. The LOI does not require a personal guaranty from the individual owners. If the business fails, the LLC dissolves and the landlord has no one to pursue for unpaid rent.

The Financial Impact

A local restaurant operator signs a 7-year lease through "Fresh Bites LLC" for 2,800 square feet at $32 per square foot NNN. The total gross rent obligation over the lease term is approximately $940,000. The restaurant closes after 14 months. The LLC has $3,000 in its bank account. Without a personal guaranty, the landlord recovers almost nothing. With a full-term personal guaranty, the landlord would have recourse against the individual owners for the remaining rent obligation, or more realistically, would negotiate a buyout of $50,000 to $100,000 to release the guarantor.

The Fix

Require a personal guaranty in the LOI for any local tenant, franchise operator, or entity with less than five years of operating history. Structure it as a "good guy" guaranty that covers rent through the date the tenant surrenders the space in good condition, or as a full-term guaranty with a burn-down after 36 to 60 months of on-time payment. The specific structure depends on the tenant's credit profile and negotiating leverage.

Mistake 7: Accepting Below-Market Rent Escalations

The Problem

The LOI specifies 2% annual rent escalations when the local market for comparable space is escalating at 3% annually. The landlord focuses on the starting rent and does not run the math on how escalations compound over a long-term lease.

The Financial Impact

Consider a 5,000-square-foot space with a starting rent of $30 per square foot on a 10-year lease. At 2% annual escalations, total rent over the lease term is approximately $1,641,000. At 3% annual escalations, total rent is approximately $1,719,000. That is a difference of roughly $78,000 over the full term, and the gap widens with every additional year. On a 15-year lease for the same space, the difference grows to approximately $168,000.

The compounding effect is what makes this mistake so costly. In Year 1, the difference between 2% and 3% is only $0.30 per square foot, or $1,500 total. By Year 10, the gap has widened to $2.60 per square foot, or $13,000 for that year alone. Landlords who focus only on the near-term impact consistently underestimate the long-term cost.

The Fix

Research the market escalation rate for comparable properties before drafting the LOI. Use commercial real estate databases, recent comparable lease transactions, and local brokerage surveys. If the market supports 3%, start at 3.5% and negotiate down. Never accept below-market escalations without a compelling reason, such as a significantly above-market starting rent.

Mistake 8: Weak or Missing Exclusivity Language

The Problem

The LOI grants the tenant "exclusive rights to sell coffee" without defining the geographic scope, the prohibited uses, or the remedies for violation. Alternatively, the LOI says nothing about exclusivity at all, leaving the landlord free to lease adjacent space to a competing use, but also leaving the tenant's attorney to demand broad exclusivity protections in the lease.

The Financial Impact

A landlord leases 1,800 square feet to a specialty coffee shop at $38 per square foot in a 30,000-square-foot mixed-use building. The tenant demands exclusive rights to sell coffee, and the LOI agrees without specifics. When the landlord later tries to lease a 3,500-square-foot space to a fast-casual restaurant that also serves coffee, the existing tenant threatens litigation. The landlord either loses the restaurant deal entirely (forgoing $133,000 in annual rent) or spends $25,000 in legal fees negotiating a resolution. Both outcomes trace back to imprecise exclusivity language in the original LOI.

The Fix

If you grant exclusivity, define it narrowly. Specify the exact products or services covered, exclude incidental sales (a restaurant serving coffee as part of its meal service should not violate a coffee shop's exclusivity), define the geographic boundary (the building, the pad site, or the entire center), and state the specific remedy for violation (typically a rent reduction, not lease termination). If you do not want to grant exclusivity, state that explicitly in the LOI so the issue does not surface during lease drafting.

Mistake 9: No Recapture Right

The Problem

The LOI does not include a recapture provision. The tenant decides to sublease the space but the landlord has no right to take the space back. The landlord is now stuck with a subtenant they did not choose, often paying below-market rent, while the original tenant pockets the difference.

The Financial Impact

A tenant leasing 8,000 square feet at $24 per square foot subleases the space to a different operator at $32 per square foot. The tenant collects $64,000 annually in profit on the sublease while the landlord receives the same $192,000. Without a recapture right, the landlord cannot terminate the master lease and re-lease directly to the subtenant (or a better-qualified tenant) at $32 per square foot. Over the remaining 7 years of the lease, the landlord foregoes $448,000 in rent they could have captured.

The Fix

Include a recapture provision in the LOI stating that if the tenant proposes to assign or sublease more than 50% of the premises, the landlord has the right to terminate the lease and recapture the space within 30 days of receiving the tenant's request. This gives the landlord the option to re-lease at current market rates. The recapture right also serves as a deterrent against speculative subleasing.

Mistake 10: Ignoring the Free Rent Structure

The Problem

The LOI grants 3 months of free rent as a tenant concession but does not address what happens to the unamortized concession if the tenant defaults or terminates early. The landlord gave away $30,000 to $60,000 in rent to secure the deal, and if the tenant leaves after 18 months, that concession was effectively wasted.

The Financial Impact

A landlord provides 4 months of free rent on a 5,000-square-foot space at $28 per square foot, a concession worth $46,667. The tenant defaults in Month 20 of a 60-month lease. The landlord has amortized only $15,556 of the concession (20 out of 60 months). The remaining $31,111 is a direct loss. If the security deposit was only one month of base rent ($11,667), the landlord recovers a fraction of the unamortized concession and absorbs the rest.

The Fix

Include a clawback provision in the LOI that requires the tenant to repay the unamortized portion of all concessions (free rent, TI allowance, and any other inducements) if the tenant defaults or terminates early. Structure the amortization on a straight-line basis over the lease term. Pair this with a security deposit large enough to cover at least the first two years of unamortized concessions.

The Cumulative Cost of LOI Mistakes

No landlord makes all 10 of these mistakes on a single deal, but most landlords make two or three on every deal. Even conservative estimates suggest that a landlord who misses three of these provisions on a mid-size retail lease leaves $30,000 to $100,000 on the table over the lease term.

Across a portfolio, these numbers compound rapidly. A landlord managing 25 retail and office leases who consistently overlooks holdover, CAM, and escalation provisions may be underperforming by $200,000 to $500,000 annually without realizing it.

How to Avoid These Mistakes

Systematize Your LOI Review Process

Do not rely on instinct or experience alone. Use a standardized checklist that covers all 15 critical provision categories. Run every LOI through the same process regardless of deal size. The LOI provisions checklist is a good starting point.

Benchmark Every Term Against Market Data

Every provision in your LOI should be supportable with market data. What is the standard security deposit for this tenant profile? What escalation rate are comparable properties achieving? What CAM recovery percentage are other landlords getting? Without benchmarks, you are guessing.

Use Technology to Catch What You Miss

AI-powered tools like CREagentic analyze your LOI against thousands of comparable deals and flag missing provisions, below-market terms, and language weaknesses in about 60 seconds. At $2 per analysis, it is the most cost-effective insurance policy in your deal toolkit.

Do Not Rush to Sign

The pressure to fill vacancy pushes landlords to sign LOIs quickly. Resist that pressure. A vacant space costs money, but a poorly structured 10-year lease costs far more. Taking an extra three to five days to review and strengthen your LOI will save weeks in lease negotiation and thousands of dollars over the lease term.

The Bottom Line

Every one of these 10 mistakes is preventable. The fix is not complicated or expensive. It requires a systematic review process, current market data, and the discipline to address every provision before the LOI is signed. The landlords who consistently outperform their peers are not smarter or luckier. They are more thorough at the LOI stage, and that thoroughness pays dividends for the entire lease term.
