CA Civ Code Section 1917.066

The lien of a shared appreciation loan, including the principal amount and all interest, whether accrued or to be accrued, and all amounts of contingent deferred interest, shall attach from the time of the recordation of the deed of trust securing the loan, and the lien, including the lien of the interest accrued or to be accrued and of the contingent deferred interest, shall have priority over any other lien or encumbrance affecting the property secured by the shared appreciation instrument which is recorded after the time of recordation of the shared appreciation instrument. However, nothing in this section or Section 1917.165 shall preclude a junior lien or encumbrance subordinate to the obligation of the shared appreciation loan.
