Real Estate LOI (Letter of Intent): what it is, why it matters, and how to use it to buy or sell with an edge

In prime real-estate transactions—whether a unique home, a residential building, a hospitality asset, or a long-term investment—it’s common to use an LOI (Letter of Intent), also known as a letter of intent. While it doesn’t replace a binding contract, a well-structured LOI can be the difference between securing a deal and losing it to a competing buyer.

Below is a clear guide to what an LOI is in real estate, what it should include, when it makes sense, and how we use it at BARNES to protect your position and accelerate closing.


What is an LOI in real estate?

An LOI (Letter of Intent) is a short, preliminary document in which buyer and seller outline the headline terms of a potential transaction: price, timeline, payment structure, conditions, and the proposed process (due diligence, deposit/arras, SPA, deed completion, etc.).

It serves two key purposes:

  1. Align expectations before either side invests time and money in technical/legal review.

  2. Structure negotiations and create a practical roadmap to move forward.

In markets such as Barcelona, the Maresme, and the Costa Brava, where exceptional product is scarce, an LOI is also a credibility signal: it shows serious intent and reduces uncertainty for the seller.


LOI vs. reservation vs. arras: key differences

To avoid confusion:

  • LOI (letter of intent): a preliminary agreement on key terms; often non-binding on the final sale, but can be binding on clauses like exclusivity or confidentiality.

  • Reservation agreement: typically “holds” the property for a short period in exchange for a reservation deposit; often precedes arras.

  • Arras contract: a stronger pre-completion commitment in Spain, usually the direct step before notary; it sets clear consequences if either party withdraws.

In complex transactions (trophy assets, international buyers, buildings), the typical path is:
LOI → due diligence → arras/SPA → completion (deed).


Why an LOI is so useful in prime transactions

1) It speeds up the seller’s decision

Prime sellers want clarity: who is buying, with what funding, on what timeline, and under what conditions. A strong LOI cuts noise and helps the seller choose your offer.

2) It lets you negotiate like a professional

An LOI defines the playing field: due diligence schedule, deliverables, warranties, and a closing structure. This reduces ad hoc renegotiations and increases execution probability.

3) It organizes due diligence and lowers risk

It defines what will be reviewed (title, liens, HOA/community status, permits, technical condition, compliance), who pays which costs, and how long the process lasts—critical for heritage assets or buildings.

4) It’s particularly effective for investment deals

In transactions involving buildings, hotel assets, or portfolios, the seller needs a fast framework. The LOI can “lock” negotiations without drafting a long-form contract immediately.


What a real-estate LOI should include

A strong LOI doesn’t have to be long—it must be precise. Key elements include:

  1. Parties and asset identification
    Address, registry/cadastral references (where applicable), annexes, and occupancy status.

  2. Price and structure
    Offered price, inclusions (furniture/fixtures or other assets), and payment structure (deposit, milestones, financing).

  3. Transaction timeline
    Due diligence period, target date to sign arras/SPA, and target completion date.

  4. Due diligence scope
    Legal, technical, planning/urbanistic, and (where relevant) tax scope; required documents and cost allocation.

  5. Conditions and contingencies
    Financing (if applicable), approvals, documentation regularization, technical deliverables, etc.

  6. Exclusivity (if requested)
    A defined period during which the seller won’t negotiate with third parties. This should be time-limited and justified.

  7. Confidentiality
    Essential in prime deals: discreet viewings, non-disclosure of information, controlled access.

  8. Binding vs. non-binding nature
    Which clauses bind (e.g., confidentiality, exclusivity, costs) and which typically do not (final completion).

  9. Governing law and jurisdiction
    Especially important with international parties.


Clauses that are often binding (and why)

Even when an LOI is “non-binding” on the sale itself, these clauses are frequently binding in practice:

  • Confidentiality: protects sensitive information and seller privacy.

  • Exclusivity: if granted, must be clearly defined and time-limited.

  • Costs: who pays what if the deal doesn’t complete.

  • Non-circumvention / no-bypass: where appropriate, prevents parties from cutting out intermediaries.

At BARNES, we pay special attention here: a poorly drafted LOI can expose you—or unnecessarily lock you in.


Common LOI mistakes to avoid

  • Quoting a price without clear timeline and proof of funds—sellers need certainty.

  • Requesting long exclusivity without real justification—often rejected.

  • Leaving due diligence “open-ended”—invites renegotiation and deal fatigue.

  • Failing to define what is binding vs. non-binding—creates legal risk and friction.

  • Ignoring occupancy, permits, or liens early—leads to unpleasant surprises mid-process.


When should you use an LOI?

An LOI is especially advisable when:

  • the asset is high value or unique,

  • there are multiple decision-makers (family office, company, co-owners),

  • the deal requires robust technical/planning due diligence,

  • one party is international,

  • it’s an investment asset (building, portfolio, hospitality).

For standard residential purchases, you may move straight to reservation/arras. In prime, an LOI brings structure and control.
