What Is a Lease? How to Read One

Lease means the contract between a landlord and tenant for the use of a property. Here is a plain-English guide to the document and its commonly used fields.

What is a Lease?

A lease is a binding contract in which a landlord grants a tenant the right to use a property for a set term in exchange for rent. It spells out the parties, the property, the term dates, the rent and deposit, and the rules and clauses both sides must follow. Property managers and lenders extract the key terms to track obligations.

Who sends a Lease, and when?

The landlord or property manager drafts the lease; both landlord and tenant sign it before move-in. Terms are usually 6 or 12 months for residential and longer for commercial.

Frequently asked questions

What is the difference between a lease and a rental agreement?

A lease fixes a term (often 12 months); a rental agreement typically renews month-to-month.

What key dates should I track from a lease?

Start and end dates, the renewal-notice deadline, and rent-due dates are the ones that carry consequences.

Can lease data be extracted automatically?

Supported leases can return configured party, date, rent, deposit, and clause fields for review. Coverage varies by layout, so compare important terms with the signed source.
