Hard money loan against a mortgage - How do i go about it

[Ronda R.]

I am borrowing money (from my parents), interest only for 6 months. House will be a flip. I want the loan lien to be filed against the house so that when I sell the title company will pay the lien holder first and that money won't be considered income for me. I am thinking I need to have a simple loan agreement drawn up by a lawyer, signed and notarized and then have a title company file the lien. Is that the process? Do I even need a title company?
