Write off the interest, repairs, "visits" to my property. 

If you are starting from scratch, its important that the policy be designed properly so as to minimize the death benefit (and fees and commissions) and maximize the cash value.I write about the policy design aspects in this discussion...https://www.biggerpockets.com/forums/519/topics/245380-paradigm-life-infinite-banking-whole-life-insurance?

Writing on the walls, holes in the doors? 

I meant to write "non-owner occupied" financing, which tends to be more expensive than the rates available to owner occupiers.   

I was wondering if I could write something up and have him sign it (he's already told me he's willing to sign) saying that he understands and agrees he owes me the amount on the paperwork, if the judge would take that into consideration and grant the money judgement.

I go out and write a contract.

I have this in writing form the lender.

Most banks would require your parents to write a letter that the money is a gift to you, ie not a loan. 

I could probably write a whole book about them.I sold all my properties except for a couple of triple net commercial properties I have.

You need to write a book someday.
