It would be awesome if you set a time to go see it, and confront him.

It doesn't have to be a conflict or confrontational, but you're going to have to ask why the rent was late and how he plans to make sure next month the rent is not similarly late.

Has anyone else been confronted with this or a similar problem?

When I confronted him on the jetting of the sewer, he got defensive even though it was discussed and I believe included in the quote. 

But...if the concerns you have are bonafide perhaps your practice is better off taking the more time intensive path of filing returns where no obligation exists and avoiding any chance of confrontation (however miniscule) with the IRS.

At the very least consider what you would need to do to be successful: deal with homeowners during the most stressful time of their lives; during financial crisis, unemployment and divorce, and the fact that most will be confrontational and consider you a predator.

In the past, they all claimed plausible deniability when confronted.

I told him I'll bring a handgun and a flashlight and will investigate by climbing up the stairs to confront the creature. 

With that being said I don’t like confrontation and I feel this is what it will lead if I tell them that if this housing isn’t suitable for you we can return their money no questions asked.
