In the comments my colleagues broadened the topic to their own personal interpretation.

For instance, there have been some  responses stating that (to paraphrase ) "you can be liable for double or triple the damages should a judge rule against you", implying that if you make a mistake in the interpretation of the deposit, you could be on the hook for much more than the amount of the deposit.

Restating your question added clarity to the interpretation of your question.  

@Anita WalterI'm not the best person to ask about the specifics of wholesaling (I have never wholesaled before) or give interpretations or guidance involving legal advice (because I'm not qualified to do so, you need a licensed attorney). 

He did not ask how to lie to the seller (although I am sure you will interpret it this way), he is asking how much information he should give to answer a question.

So how do you interpret this data? 

My interpretation of this is that you are not allowed to deduct interest on any borrowed money to finance a business, including Real Estate.

I also wanted to let you know like-kind is interpreted as investment real estate for investment real estate.

Sounds rough, but it's true as we have had the experts from the Fair Housing Offices tell us this as that is how they interpret the laws.  

At lease if I was your tenant that is how I would interpret the language.If she mailed it on the first, based on your lease, and considering the post office is beyond her control I would say she was not late.
