This is a lease option contract and I dont understand this:

((( RENEWAL: At seller's complete discretion, Buyer may renew the lease option for ___term(s) of (12) months. )))

QUESTION: DOES THIS MEAN I CAN ONLY RENEW THE LEASE OPTION FOR 12 MONTHS OR CAN I DO 80 MONTHS?

The way I read this, buyer can renew for XXX amount of 12-month terms. Just put (6) in the ___ spot. That'll give you 72 months max (6 x 12 month terms).

Note that it also says "at seller's complete discretion" which I read to mean that they can revoke it for whatever reason they want.
