The Department of General Services, if the Director of Parks and Recreation finds that the use would be compatible with the ultimate use of the real property as a unit, or part of a unit, of the state park system and with the sound management and conservation of resources within the unit, may make agreements with respect to any real property acquired pursuant to subdivision (b) of Section 5096.231, and the Executive Officer of the State Coastal Conservancy may make agreements with respect to any real property acquired pursuant to Section 5096.232, for the continued tenancy of the seller of the property for a period of time and under such conditions as mutually agreed upon by the state and the seller so long as the seller promises to pay such taxes on his or her interest in the property as shall become due, owing, or unpaid on the interest created by the agreement, and so long as the seller conducts any operations on the land according to specifications issued by the appropriate director or officer to protect the property for the public use for which it was acquired. A copy of the agreement shall be filed with the county clerk in the county in which the property lies.
