If you fail to follow the rules, you may open your personal assets to a lawsuit.

This is only one example of multiple instances of failed customer service.

The reality of it is if you're going to rent to people you are a business owner and viewing your assets that way is something that they fail to point out a lot of times in books and seminars urging you to take immediate action.
