Will you accept five dogs and a miniature horse and let me pay the deposit in 17 installments of $52.94 and pay my rent every month on the 24th?

It gets expensive quickly for the seller if they fail to deliver possession (of course evicting/collecting is a horse of a different color depending on where the property is located, but at least you have the protection of a legally-binding document that is enforceable):17.

I agree with Bill, the cart is before the horse here.
