Usually the payment of a commission to the brokerage is contingent upon finding a buyer for the real estate, the successful negotiation of a purchase contract between the buyer and seller, or the settlement of the transaction and the exchange of money between buyer and seller.
The transponder cost for each account type is the same. The SunPass Portable cost is $19.99 plus tax, plus a required $10.00 minimum initial balance. The SunPass Mini Sticker Transponder cost is $4.99 plus tax, plus a required $10.00 minimum initial balance.
The regular SunPass is a plastic box. It costs around $40, with a $15 credit. It can be moved from car to car, although technically each car you use it in must be registered. It will still work without that registration, however. If you use the toll roads in Florida frequently, that is the best option.
