One of the ways that construction companies reduce their construction equipment lease financing costs is to pick out a payout option at the end of the lease that requires a large lump sum of at least 10% of the lease amount in order for the lessor to be able to retain the asset.
This is called a balloon payment that allows the monthly lease payment to be lower versus something that is fully amortized.
This is also very beneficial to the leasing company as the amount of the balloon payment will remain outstanding for the entire lease term, earning interest income in the process for the lessor.
