The typical means of placing a lien on real property is with a combination of a promissory note/security agreement and a deed of trust.
I cannot provide you with the necessary documents, but I can direct you to forms available online that will accomplish the lien. These forms are not free, however, and any forms that you could find for free will probably have problems, because they will not be designed for do-it-yourself use.
This link will direct you to a webpage containing a promissory note and deed of trust. They are listed as #1 and #6 on the page. The total cost is $94. There are other forms that are less expensive, but I would be reluctant to point you towards them, because they are not provided by a licensed Arizona attorney who must stand behind them if there is a problem.
Once you have filled out the forms and have your borrower sign with a notary acknowledgement, you must record the deed of trust (but not the promissory note) with the county clerk in the county where the property is located. There will be an additional filing fee for the recording, however, the amount varies by county, so I can't tell you what it may be.
Let me know if you have further questions.
