If such real estate is to be leased for residence purposes only, and does not include the lease of any agricultural or grazing lands, it may be leased on terms of month-to-month leasing by resolution of the county commissioners without public auction or advertising. The resolution of the county commissioners in such cases shall recite the monthly rental of such property. If any person shall offer to pay in advance a monthly rental twenty-five percent in excess of the rental then being paid for such residence property, the county commissioners must accept the same upon deposit of such rental in advance.
