Yes, roughly 2/3 of the rent is applied towards the optional purchase, so you can decide to buy Boomer at any point during the rental to save money. For example, if you have rented Boomer for 3 months, you've paid $1,800. $1,200 of that rental is applied towards the purchase price and you can buy Boomer for $13,250, which is $14,450 - $1,200.
