How Should Private Lender Pay Me??

[Joseph A.]

I've been borrowing money against my properties, but up until this point I've only borrowed small amounts and out of the 3 people that have loaned me money two have given me cash and the other person used zelle. When zelle was used the money had to be transferred in two parts due to limits for the day. I'm at the point where I'm going to start borrowing larger amounts. I signed a promissory note for two of them and made a handshake agreement with the other person. How do you guys receive payments from your private lenders(not hard money disguised as private lenders) and structure everything?
