1. You assume that no negotiation is allowed. But the words “standard equipment lease” should not be misconstrued as an absolute prohibition against changes.

2. You rely on one person’s opinion. It generally helps to seek advice from several experts and business advisers.

3. You focus on the monthly payment instead of the overall price. If you can whittle down the price, the monthly payment will drop.

4. You accept a vague buyout clause. Make sure you understand what the terms are. If necessary, insist on a rewrite.

5. You become trapped in the lease. Check out any terms that might extend the lease without any specific approval.
