For the purposes of this subdivision, if the replacement dwelling is a mobilehome, the term "mortgage," as defined in subdivision (h) of Section 7260, shall include those liens as are commonly given to secure advances on, or the unpaid purchase price of, mobilehomes, together with the credit instruments, if any, secured thereby.
However, the displacing agency may extend the period for good cause. Also, the displaced owner and the public entity may agree in writing that the displaced owner may remain in occupancy of the acquired dwelling as a tenant of the public entity on the conditions that the displaced owner shall only be entitled to the payment authorized by this section on the date on which the owner moves from the acquired dwelling and that the payment shall be in an amount equal to that to which the owner would have been entitled if the owner had purchased and occupied a replacement dwelling one year subsequent to the date on which final payment was received for the acquired dwelling from the public entity.
