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'! 

He then wanted to talk about his odds of being audited and what numbers he needed to report to fly under the radar.I interrupted him part way through a rant against taxation, government, etc and said "I don't think I'm the right CPA for you."  

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.

Section 8 will require you to jump through more hoops, be audited, be inspected, etc. 

To set-up for payment processing on your own and pass PCI and/or ACH requirements can be expensive (development, audit and assurance) and, as @Jimmy Moncrief warned, the liability is almost certain to outweigh the benefit of brand control.For a small operation, I would recommend you find a storefront hosting provider or payment gateway and simply throw the session to it from your website.

Both of the places I've lived were in old renovated hotels, turned into 55+ housing units in the old downtown areas.As an owner/manager, you'd have to deal with several govt agencies, audits and inspections, but you'd always have a waiting list, from my experience at least in CA.
