Structuring a private mortgage for a family member who is financing a purchase

[Nate Gelinas]

Hey guys. Long story short, I have a family member who may be financing a purchase. They are lending me $45k, 5 year note @8%, interest only payments for the duration, lump sum due at the end.

Now I would like to set up this member to have a mortgage/lien on the property that I am purchasing simply to legitimize the loan and make them feel comfortable with the whole transaction.

Can anyone provide any insight, or point me towards a good book or anything that I can read up on?

Appreciate any help!
