A letter of intent in real estate is a preliminary document, usually sent by a buyer or tenant, that proposes the key terms of a deal before either side commits to a formal contract. Most of its provisions are non-binding. A few routinely are binding, and in some circumstances the whole document can be enforced as a contract even when it says it isn’t. That gap between how an LOI is labeled and how a court may read it is the part worth understanding before you sign one.
What a Real Estate LOI Contains
An LOI focuses on the terms that matter most to the parties and any absolute deal-breakers. It isn’t meant to cover every term that will appear in the final contract. Certain elements show up in nearly every one:
- Full legal names and contact information for the buyer and seller, or landlord and tenant.
- The property’s address, legal description, and relevant characteristics such as suite numbers or acreage.
- The proposed purchase price, or for a lease, the rental rate and what it includes (utilities, maintenance, common area charges).
- The proposed earnest money structure and conditions for its release. The actual deposit is made later, when the formal purchase agreement is signed.
- A due diligence period during which the buyer can inspect the property, review financials, and investigate title.
- A target closing date or timeline.
- Contingencies such as financing approval, satisfactory inspections, or zoning confirmation.
- An exclusivity period during which the seller agrees not to negotiate with other potential buyers.
- Confidentiality restrictions on sensitive information exchanged during negotiations.
In commercial deals, the due diligence section often lists documents the seller must produce: environmental reports, rent rolls, operating statements, existing leases, title reports, tax bills, utility records, and any pending litigation. Spelling that out in the LOI prevents arguments later about what the buyer is entitled to see.
Both sides sign the LOI for it to take effect. A one-sided letter from the buyer without the seller’s signature is just an offer, not an agreed framework.
Which Parts Are Binding and Which Aren’t
The core deal terms — purchase price, closing timeline, contingencies — are almost always non-binding. Neither side is obligated to complete the transaction based on those terms alone. Well-drafted LOIs then carve out specific provisions that do create enforceable obligations:
- Confidentiality. Both parties agree not to disclose sensitive financial or business information shared during negotiations.
- Exclusivity, often called a no-shop clause. The seller agrees not to solicit or accept other offers for a specified period.
- Expense allocation. Who pays for due diligence costs like environmental assessments, surveys, or appraisals.
- Governing law. Which jurisdiction’s law controls the interpretation of the LOI itself.
Enforceability turns on the language in the document. A properly drafted LOI explicitly states which sections are binding and which are not, typically with a blanket non-binding statement followed by specific carve-outs. Common disclaimer language reads something like: “This letter is an expression of mutual intention only and does not constitute a binding agreement, except for Sections [X], [Y], and [Z], which shall be binding upon execution.”
Vague or sloppy language is where problems start. An LOI that fails to clearly separate binding from non-binding provisions leaves room for a court to read the document differently than either party intended.
When a “Non-Binding” LOI Becomes Enforceable
Labeling an LOI non-binding does not guarantee a court will treat it that way. Courts in multiple states distinguish between two kinds of preliminary agreements, and the label the parties chose matters less than the substance of what they wrote.
A Type I preliminary agreement is one where the parties have already agreed to all the material terms. If a court finds the LOI contains every essential element of the deal, it can enforce the agreement regardless of non-binding language. The reasoning is direct: if you’ve agreed on the price, the property, the timeline, and every other term that matters, calling it non-binding doesn’t change the fact that you made a deal. A Type II agreement, by contrast, contains open terms that still require negotiation. Courts will generally respect non-binding language in a Type II situation, though they may still impose an obligation to continue negotiating in good faith.
Several factors go into deciding which category applies:
- Whether the LOI expressly reserves the right not to be bound absent a final signed agreement.
- Whether the language is clearly non-committal or reads more like a completed contract.
- Whether either party has already started performing under the agreement’s terms.
- Whether the parties agreed on all material terms or left significant issues unresolved.
- Whether the type of transaction involved is one customarily memorialized in a formal written contract.
In one instructive case, a Maryland appellate court found an LOI binding on the parties even though they never signed a final lease. The court concluded that the LOI set forth all the material terms and only non-essential matters remained open. The losing party was ordered to sign the lease it had previously rejected. That outcome surprises people, but it follows directly from the Type I analysis: if your LOI reads like a complete deal, a court may treat it as one.
The Statute of Frauds adds another layer. Every state requires contracts for the sale of real property to be in writing, signed by the party being held to the deal, and containing the essential terms. An LOI that checks all three boxes can satisfy the Statute of Frauds, giving a court the legal basis to enforce it as a real estate contract even if the parties intended it as preliminary.
Partial performance strengthens the case for enforcement. If the buyer starts spending money on inspections, the seller takes the property off the market, or either side begins acting as though the deal is done, those actions make it harder to argue the LOI was just a casual expression of interest.
The Good Faith Obligation
Even when the deal terms are genuinely non-binding, signing the LOI can create an implied obligation to negotiate in good faith. This catches people off guard. They assume non-binding means they can walk away for any reason at any time. Technically they can decline to agree on final terms. But they can’t sabotage the process.
Good faith negotiation means participating honestly and reasonably. Courts have found parties liable for deliberately stalling, imposing unreasonable new conditions designed to kill the deal, or walking away for pretextual reasons after the other side invested substantial time and money in reliance on the LOI. Damages can be significant. At minimum, the wronged party may recover out-of-pocket costs: attorney fees, due diligence expenses, and the cost of foregoing other opportunities while tied up in negotiations. Some jurisdictions have gone further, awarding the full benefit of the bargain the injured party expected from the deal.
The practical point: don’t sign an LOI unless you genuinely intend to negotiate toward a deal. Using one to lock up a seller’s property while you shop for something better, or to extract confidential financial information with no real intention of closing, creates legal exposure even though the document says non-binding at the top.
How This Differs From a Purchase Agreement
The LOI and the purchase agreement are often confused, and the distinction matters. An LOI captures the high-level business terms the parties have tentatively agreed on. A purchase agreement is the comprehensive, legally binding contract that governs the entire transaction from signing through closing and sometimes beyond.
The purchase agreement covers everything in the LOI plus a substantial amount of additional detail: representations and warranties from both parties, default provisions and remedies if someone breaches, proration of taxes and expenses, title and survey requirements, conditions for termination or extension, and post-closing obligations. Violating a purchase agreement carries real legal and financial consequences, including forfeiture of earnest money deposits and potential lawsuits for damages.
The sequence runs one direction. The LOI comes first to align expectations and establish key terms. Once both sides are satisfied with the framework, attorneys draft the purchase agreement incorporating those terms along with the legal protections and procedural details a formal contract requires. The LOI’s job is done at that point, though its binding provisions (confidentiality, exclusivity) may survive.
Protecting Yourself Before You Sign
Make sure the LOI clearly states which provisions are binding and which are not. A blanket non-binding statement at the top is a start, but it’s not enough on its own. Each binding provision should be explicitly identified, and the non-binding sections should include language reserving the right not to be bound absent a signed definitive agreement.
Avoid including more detail than necessary. Every material term you add to the LOI strengthens the argument that the parties reached a complete agreement. If you want the LOI to remain non-binding, intentionally leave some terms open for future negotiation. That keeps the document in Type II territory where courts are more likely to respect the non-binding label.
Have an attorney review the LOI before you sign it. This isn’t the place to cut corners on legal fees. An attorney can spot language that might inadvertently create binding obligations and ensure the confidentiality and exclusivity provisions actually protect your interests. The cost of a review is trivial compared to the cost of discovering months later that you accidentally committed to a deal you can’t complete.
Be careful with your conduct after signing. Don’t act as though the deal is closed. Don’t start making improvements to the property, publicly announce the acquisition, or take other steps that suggest you consider the transaction final. Partial performance is one of the factors courts weigh when deciding whether a preliminary agreement is binding, and your actions can undermine the non-binding language you carefully negotiated.
