For better or worse, most banks will require you to sign the same set of documents that contain similar languages.

The real problem with this theory is that there is no specific language in the tax code or significant case law to provide meaningful guidance. 

This is partly true, but the true intent of that language is to prevent undisclosed sales/transfers that would leave the Lender without an easy recourse in case the note is then not being paid.

This got me thinking about adding a language to lease to deduct (from security deposit) costs related to repainting or refreshing.

The term de minimis costs means amounts (other than employee compensation and overhead) paid in the process of investigating or otherwise pursuing a transaction described in paragraph (a) of this section if, in the aggregate, the amounts do not exceed $5,000 The quoted Regulations apply to acquisition of a trade or business as the language above explicitly states.I disagree that this De Minimis provision applies to financing acquisition of investment properties.

Most people look at me like I'm speaking another language when I start taking about any kind of investing.

Probably a written notice with specific language and period of time to comply; possibly a fine if provided for in the Agreement or House Rules.

Essentially, you could have 5 employees on your team but it appears like you have 1 because everybody speaks the same language.

Then they gave you this piece of paper with a "yes" or "no" place to check off, some disclaimer language, and a place to sign your name.

The first thing you need is some education - some knowledge, then a network of investors to buy from and sell to.Networking will also help you learn the language and the process.
