Insurance clause in note?

[Eric Miller]

Good morning real estate gurus. I have a question about a house we are selling. We own it free and clear, and have accepted an offer for about 34% down with the rest seller financing. My question is, should there be a clause in the note that the borrower will have insurance on the property, and keep the property taxes paid? I know that all of the bank loans that I have had, had this clause. Another question, the note he had drawn up has an acceleration clause, but there is no mention of how default is triggered.

I apologize if I left out any important information, I read here quite a bit, but post little.

Thanks in advance, Eric
