If he pays his rent on time and there's no serious criminal activity that we can prove, we can't do anything. 

Ultimately it was your fault (or your CPA's fault) for not knowing the deadline, but if it is a first time offense occasionally the IRS will waive the penalty.It doesn't hurt to call and ask for the penalty abatement.

just sayinWhen you feel that your first line to your response should be "don't take offense", you can almost guarantee that the person receiving it will be offended. 

They'll be happy to boot her if she has a disallowed roommate/allowing criminal activity (roommate was high)/not paying rent/not following the lease.  

I'd then run her criminal & credit history and get info on where she works and how much she makes.

I would do a comprehensive screening report (credit+criminal+eviction) for each of them to get a better idea of what kind of renters they will be!

Say the phrase "fat loss" and your ad will get canned for offensiveness several steps before the submit button LOL.

We rarely bother with that any more because: people with stable employment, good credit without late payments, not run up every card they own, no criminal record, no evictions, and present themselves as nice, decent people are generally not psychopaths once they get into their unit.

My solution, as to not be a negative nancy (no offense to nancies), would be to handle it like an RV park, and then lease the operation to someone.

Does a PM have the resources to do credit and criminal checks, check landlord references and apply standardized screening criteria to all potenital tenant applicants....Yes.
