A commercial real estate letter of intent — usually just called an LOI — is the first real document of a deal. It sits between a handshake and a lease. It is not binding on most terms, but it sets the economic and structural frame for everything that follows. A sloppy LOI means a rough lease negotiation. A tight LOI means the attorneys can do their job instead of re-litigating what was already agreed.
Almost every LOI template floating around online is either a 1997-era Word document or a paywalled download from a site that wants your email. This guide walks through what actually belongs in an LOI, section by section, with the language we use when we draft them. If you just want the template, scroll to the end — or skip to the LOI Generator and build yours in three clicks.
What a Letter of Intent Actually Does
An LOI pins down the business terms of a commercial lease before either side spends money on legal review. It is usually 2-4 pages. Most of it is non-binding — both sides reserve the right to walk away. A small number of provisions are binding, and it matters which ones you mark as which.
The LOI has three jobs:
- Align on economics. Rent, term, escalations, concessions, tenant improvement allowance, free rent, NNN or gross structure.
- Align on deal shape. Premises definition, use clause, exclusivity, options, personal guaranty.
- Set timing. When the lease will be delivered, how long to negotiate, when the deal dies if the lease isn't signed.
If any of those three are vague in the LOI, they will be vague in the lease, and you will find out a year from now when a dispute comes up.
The Sections Every Commercial LOI Should Have
Every LOI we draft follows the same skeleton. Some sections get longer or shorter depending on the deal — retail LOIs spend more time on exclusivity and co-tenancy, office LOIs spend more on tenant improvement allowances and signage — but the spine is the same.
1. Parties
Full legal names of the landlord and tenant entities. Not the brand name, not the DBA. If the tenant is a new LLC formed for the lease, say so and flag whether a personal guaranty is expected (it probably is, especially for restaurants, retail, and any first-time operator).
2. Premises
Exact address, suite number, and rentable square footage — plus the measurement standard used (BOMA, gross, usable). For retail, include a site plan or pad designation. For multi-tenant office, clarify common area load factors. Vague premises definitions are the single most common source of lease disputes we see.
3. Use
What the tenant will be doing in the space. Do not agree to "retail" or "general office use" — that is too narrow later when you want to change concepts, and too broad for the landlord who wants control over the tenant mix. A solid use clause names the primary use plus any ancillary activities the tenant may need: "a full-service restaurant serving [cuisine] with on-premises alcohol service, plus incidental catering, delivery, and retail sale of branded merchandise."
4. Term and Commencement
The initial term length, any renewal options (how many, how long, at what rent), and when the lease starts. Commencement language is where deals get messy. Distinguish between:
- Lease commencement — when the lease is signed and tenant obligations begin
- Rent commencement — when rent actually starts being paid (often after a build-out period)
- Possession — when the tenant actually gets keys
If the landlord is building out the space, the LOI should say rent commences on the earlier of (a) a fixed number of days after substantial completion or (b) the tenant opening for business. The worst LOIs are silent on this and it becomes a two-month fight.
5. Base Rent and Escalations
The starting rent (usually expressed in dollars per rentable square foot per year), the payment cadence, and the escalation structure. Typical patterns:
- Fixed bumps: 3% per year, or specified dollar amounts in years 2, 3, 4, 5.
- CPI-based: tied to the Consumer Price Index, usually with a floor (2%) and cap (5%).
- Fair market rent at renewal option: more common for longer deals with multiple options.
Be specific. "Market rent at renewal" with no process for determining market is a landlord-favorable trap.
6. Operating Expenses (NNN or Gross)
This is where most tenants get surprised. Clarify upfront whether the deal is:
- NNN (triple net): tenant pays base rent plus their pro-rata share of property taxes, insurance, and common area maintenance (CAM).
- Modified gross: tenant pays base rent plus some expenses, usually with a base year stop.
- Full-service gross: tenant pays one all-in number, landlord covers everything.
If it's NNN, ask for an estimated current NNN charge and an audit right. If it's gross, ask whether there is an expense stop and what counts toward it. We have seen "gross" leases that carved out utilities, janitorial, HVAC maintenance, and property taxes — leaving the tenant paying 80% of what a NNN deal would have cost.
7. Tenant Improvement Allowance (TIA) and Free Rent
Dollar amount per square foot of TIA, what it covers, and whether it's paid by the landlord directly to contractors or reimbursed to the tenant. Plus any free rent or abated rent — how many months, and whether it includes NNN charges or only base rent. (It should include NNN if you can get it.)
8. Exclusivity and Co-Tenancy (Retail)
For retail LOIs, this section is often the most important. Exclusivity is the tenant's right to be the only [concept type] in the center. Co-tenancy is the tenant's right to reduce rent or terminate if anchor tenants leave. Both are negotiated in the LOI, not the lease — once the business points are set, the lease language is just cleanup.
9. Personal Guaranty
For smaller tenants, landlords almost always ask for a personal guaranty. Common structures:
- Full-term guaranty — guarantor is on the hook for the full lease
- Burn-down guaranty — guaranty decreases over time if tenant performs
- Good guy guaranty — guarantor is liable only through the date the space is returned in good condition
Negotiate this in the LOI. Asking for it to come off the lease after it's been drafted is much harder.
10. Binding vs. Non-Binding
State clearly which provisions are binding and which are not. Standard pattern: everything is non-binding except (a) confidentiality, (b) exclusivity during the negotiation period, and (c) expense reimbursement if the deal dies.
11. Expiration
When does the LOI itself expire if the lease isn't signed? Thirty to sixty days is standard. Beyond that, one side is usually getting strung along.
Mistakes We See in 80% of LOIs
After reviewing thousands of these, a few patterns repeat:
- No TIA disbursement process. The LOI says "$50/sf TIA" but doesn't say how or when it gets paid. That fight costs months in the lease draft.
- Silent on holdover. What happens if the tenant stays past lease end? Most leases set holdover rent at 150-200% of base. If the LOI is silent, the landlord writes whatever they want into the lease.
- No SNDA or estoppel language. For tenants with lenders or institutional capital, these are material. Put a placeholder in the LOI so it doesn't surprise anyone later.
- Vague assignment/sublease rights. If the tenant might sell the business, assignment rights need to be in the LOI. "Landlord consent not to be unreasonably withheld" is the baseline.

Before You Send It
Three last things worth checking before the LOI goes out:
- Do the numbers math? Base rent × SF × term + escalations should produce a number you are comfortable paying. People send LOIs without actually running the aggregate rent.
- Does your attorney know it's coming? Even though the LOI is mostly non-binding, the exclusivity and confidentiality sections are. Your attorney should see it before it's signed.
- Is there a parallel negotiation happening? If you are evaluating multiple spaces, the exclusivity provision is what gets you out of the deal cleanly if you sign an LOI elsewhere.
An LOI is not the lease, but it is what the lease will look like. Spend the hour getting it right.
