> Non-binding written summary of agreed deal terms — the basis for lease negotiation.

## TL;DR

- Non-binding written summary of agreed deal terms — the basis for lease negotiation.
- The LOI is the most important pre-lease document.

# LOI (Letter of Intent)

*Lease structure · Global*

## Short definition

Non-binding written summary of agreed deal terms — the basis for [lease negotiation](/topics/class-a-lease-negotiation).

## Full definition

The LOI is the most important pre-lease document. Once an LOI is countersigned, deviating from its terms in the lease draft is a meaningful negotiating challenge. Insist on a thorough LOI — every economic term, every option, every key carve-out should be captured.

## Why this matters for Class A leasing

LOI (Letter of Intent) is part of the lease structure vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
