25 CFR § 162.222 - How much rent must be paid under an agricultural lease?
(a) An agricultural lease must provide for the payment of a fair annual rental at the beginning of the lease term, unless a lesser amount is permitted under paragraphs (b) through (d) of this section. The tenant's rent payments may be:
(1) In fixed amounts; or
(2) Based on a share of the agricultural products generated by the lease, or a percentage of the income to be derived from the sale of such agricultural products.
(d) We will grant or approve a lease at less than a fair annual rental, as previously determined by an appraisal or some other appropriate valuation method, if the land is subsequently advertised and the tenant is the highest responsible bidder.
