I seem to remember her saying something like home office expenditure is an audit red flag as well.

;-) Jay:I've worked in information security for almost 30years (mostly in the design side, but spent a fair amount of time performing security audits of communications systems and infrastructures) and I think you are over reacting.The OP asked about providing Internet and/or cable service to his tenants, not to the public.In the buildings where we have Internet for our building monitoring and provide "complementary" internet, each unit has its own (layer-2) segregated network.  

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

I wonder if they separated the utilities, if you feel their was something fishy going on, contact your utility company and share your concerns and ask if they can do an audit and see where the utilities are and who is responsible for what.

thanks guys n gals yep the lease agreement in this instance that she just signed says leased premises are for residential use not business use.. her argument is occasional client visits to her home are normal in her profession.we are still sticking to the presiding reasoning that disclosing the owner's SS# isn't warranted as the lease prohibits business use, thanks but she is being persistent and threatened to petition IRS that our owner's rent roll should be 'audited'!

I've audited thousands of amortization accounts and I've also disproven every variant of this theory on Google sheets posted earlier in this thread.

They have to deal with a lot of inspections and audits, etc., but there is always a waiting list and the tenants are pretty mellow for the most part.

Solar is a fixed amount all year long and then at the end of the year they do an audit and either charge us for the energy we created above what was estimated, or refund us the amount we paid for that wasn't created. 

We've been slowly, but steadily, moving to electronic locks which we can manage remotely and if necessary, audit the access history.
