# Leases Overview

> Overview of the Leases API endpoints and functionality

The Leases API provides endpoints for managing rental lease agreements and their lifecycle throughout the tenancy period.

## Key Concepts

### Lease Terms

Leases define the rental agreement parameters:

* **Duration**: Start and end dates for the lease period
* **Rent Amount**: Monthly rental amount for the unit
* **Execution Status**: Whether the lease has been signed (`isExecuted`)
* **Unit Assignment**: Specific unit covered by the lease

### Lease Relationships

* **Households**: Leases are associated with specific household units
* **Properties**: Connected to the property where the unit is located
* **Units**: Specific unit being leased
* **Renewal Offers**: Future lease renewal opportunities
* **Rent Changes**: Historical rent adjustments during the lease term

### Lease Lifecycle

* **Creation**: Initial lease offer and terms setup
* **Execution**: Lease signing and activation
* **Management**: Ongoing lease administration and modifications
* **Renewal**: Lease extension and renewal processes
* **Termination**: Lease end and move-out procedures
