First off... if your intent behind obtaining a land patent is to protect the land from the potential assaults inherent with it being in equity, then why would you later desire to move the land back into equity by contracting with some third person who will more than likely have to receive financing from a bank or other financial institution.?

Secondly, if you already have a mortgage on the property (house and other appurtenances), and it is your desire to sell it, then sell it. Right now, all you are in possession of is a Warranty Deed, which only carries 'color of title', and that is all that will be passed on to the new purchaser. If you read the warranty deed and the mortgage, you will find that nowhere does the previous seller agree to provide to you the REAL title to the land or the property. As for the expressed title insurance.. another fraud... nowhere does the insurance package indicate that the title company will defend the title; that is the responsibility of the previous owner (seller).

On another note. If you are living in the state of florida, you might want to look up the term "Ultimate Equitable Owner".. Here in florida, no corporation can declare itself to be the Ultimate Equitable Owner of any parcel of land.
