I will need more information to try to help you with this. What city are these addresses located in. I will also need any information you have on the owners of each of these addresses, such as if they are private individuals, a rental company or anything else you know about them.
Really the only way to know if they would offer you a lower rate for your rent would be to ask them. Again, since this is a private individual rather than a rental corporation they may be willing to negotiate the price in order to get someone into the space. A lesser amount of money for rent for the amount of time of your agreement versus no renter can make someone more willing to accept a lesser price, but if there are other individuals interested in renting the space as well it is possible that they will want the full price. Keeping an open and honest line of communication with the owner can go a long way.
