I bet the IRS would love to audit someone like that.. :)

For instance, if a property goes empty and you were expecting rents during that time - leave it empty for a couple of months - nothing forces you to keep it rented.And here's the other thing, if you get audited, you are the unlucky 0.3%, and if a red flag is raised during the audit, you will get audited again and again.

A Property Manager with hundreds of applicants every year will have to be more open about their processes to avoid a Fair Housing accusation or to survive an audit.

I'm going to set up a system of recurring reminders on something like a semiannual basis to audit all of my negotiable expenses.

@Aaron Grant from what I have heard, to much paperwork, and fear that it will trigger an audit, which I guess used to be kinda true many years ago but from what I have heard, not anymore.

Now, after you've refused to rent to someone, and they wind up homeless, they land on the city's doorstep, and the city listens to their sob story, decides you are wrong, and suddenly you have tax audits, building inspectors, and enough alphabet soup to DROWN you in your life. 

Utility customers can then request an energy audit and receive a report on ways to increase energy efficiency.
