What happens when a tenant is late on their rent?

Late rent payments will incur an 8% additional fee. We send the tenants a letter and contact them directly to ask when they will pay their outstanding rent. Our intention is to always try to work things out with the tenant if they are responsive and want to pay their outstanding rent. However, if they are non-responsive and do not pay their rent in a timely manner then we may need to start legal proceedings to evict them and send them to collections. However, evictions are extremely rare and we try our best to avoid those situations.
