Leasing contracts have a variety of different purchase options available. This client wanted the monthly lease payment that fit their budget. A lease with a dollar purchase at the end of the lease is significantly more expensive than one that has a "fair market value" purchase. It is much like leasing a car. You have a "trade in value" at the end of the lease. Obviously, if the purchase option was a dollar, then the monthly payments would be much higher.
Everything was clearly spelled out in the leasing agreement that was signed. The different options were explained, and the payment plan was selected. This person signed the lease, and the statement "I have read this contract and understand the provisions of this agreement". We have placed literally thousands of leases and object to this persons statements.
