48 CFR 7.402 - Acquisition methods.
(1) Generally, the purchase method is appropriate if the equipment will be used beyond the point in time when cumulative leasing costs exceed the purchase costs.
(2) Agencies should not rule out the purchase method of equipment acquisition in favor of leasing merely because of the possibility that future technological advances might make the selected equipment less desirable.
(1) The lease method is appropriate if it is to the Government's advantage under the circumstances. The lease method may also serve as an interim measure when the circumstances -
(i) Require immediate use of equipment to meet program or system goals; but
(ii) Do not currently support acquisition by purchase.
(2) If a lease is justified, a lease with option to purchase is preferable.
(3) Generally, a long term lease should be avoided, but may be appropriate if an option to purchase or other favorable terms are included.
(4) If a lease with option to purchase is used, the contract shall state the purchase price or provide a formula which shows how the purchase price will be established at the time of purchase.
