If you have a partner somewhere you need to document your operating agreement.

Internally, this means they can document the business account requirement as in place to "facilitate that annual audit" of the business, and not as a high pressure cross-selling technique, in order to have their ducks in a row in case THEIR books are audited, and there potentially might not be a thing you could do about it. 

But, based on blog posts and info products from Seth Williams, there's another piece: He said most states have a "supporting documentation" form (the name is not consistent) that tells the city or town the property is associated with that the transaction has occurred, and it essentially allows them to adjust who the tax bill will go to.

@John Bauer Simple things - for example, whenever I send a purchase agreement to my attorney, he adds in all the pertinent dates to his calendar, so the day my money goes hard or an option expires, or I have to get a document to the other party, I get a call from his secretary...

HAve seller complete sellers disclosure document, sign a sales agreement, perform any inspections detailed in the agreement, deposit earnest cash with closing agent to open escrow.

It's essentially a document that the tenant signs affirming certain facts.
