A surviving spouse may remain in the mansion house free of charge for one year, except that such real property may be sold within that time for the payment of debts of the decedent. If the real property is so sold, the surviving spouse shall be compensated from the estate to the extent of the fair rental value for the unexpired term, such compensation to have the same priority in payment of debts of estates as the allowance for support made to the surviving spouse, minor children, or surviving spouse and minor children of the decedent under section 2106.13 of the Revised Code.
