That balance along with dealing with investors, auditors etc.

In Ohio, you can check local comparables on the county auditor site; this takes time and patience.  

I’m a CPA (originally an auditor, now in consulting), so I understand the importance of keeping accurate accounting records.

Then go to the county auditor real estate website and find the owner.

He was also county auditor for 29 years, but has been retired from that for a few years now.

I am a Workers Comp insurance auditor, therefore I work with business owners everyday and it seems that many business owners are looking to sell and get out of the state due to a combination of wage increases, insurance requirements and the general CA work force.

An invoice or receipt will help but if you have other issues the auditor is unlikely to trust this. 

@Brittany Guimond no idea why you wouldn't have a business credit card to COMPLETELY separate your peronsal and business expenses.How likely do you think an IRS auditor will ask for all your personal credit card and bank account statements to test that you haven't reimbursed anything you shouldn't have?

The auditor will ask for your log. 

Auditor will look at the facts and circumstances, there isn't a "loophole" here.
