Owner finance deal question

[Serge S.]

I'm considering packaging up some 4plex buildings into an owner finance deal. Looks like a fair win win deal. I am offering very fair terms and the deal will cash flow for the buyer. This would be my first real owner finance where I am on the financing side. My questions for the pros that have done it:

Any issues with the SAFE Act to consider?
Would you use a lawyer to draft the deed of trust and promissory note or online template?
If using a lawyer, any AZ recommendations? All the legal help I've had has been pretty shoddy and unresponsive.
If using templates it would be great if you could share those.

All help and advice is appreciated.
