When you rent with an option to buy or rent to own, usually only a portion of the rent gets credited towards the purchase so that might not be the best way to go. Typically, you simply need to sell the coop first, then buy. You can certainly start looking but why incur the additional expense of renting when most certainly you're already paying maintance charges for your coop.
