English to Spanish Bus/Financial Accounting Leases Accountancy

"...if the lessee has an option to purchase the asset at a price that is expected to be sufficiently lower than fair value at the date the option becomes exercisable for it to be reasonably certain, at the inception of the lease, that the option will be exercised, the minimum lease payments comprise the minimum payments payable over the lease term to the expected date of exercise of this purchase option and the payment required to exercise it."

Yo vengo traduciendo la expresión "minimum lease payments" como "pagos de renta mínima", pero no estoy muy convencida...
