So, you always pay the rent on time.
Evictions are one of the many unpleasant things that can happen to a tenant.
Ask anyone who have had a sheriff tack, on a three day notice to quit, on the door. Ask anyone whose personal possessions were thrown out on the street. Even a 30 day notice to quit can cause a panic attack. This doesn't happen to just deadbeats either. Many landlords illegally evict long-term tenants, especially if the eviction will result in the property being rented at a higher price due to rent control.
