It may not be possible to lower your rent payment, but it is possible to get some money back if you pay on the internet. Instead of paying with a check or with cash, pay with a credit card that gives you rewards points -- with some cards, these can be redeemed as money. You may get one or two percent back for every dollar that you spend. If you route all of the payments through this card, that can be a lot of money. You can make a rent payment online and then get some of the money back later.
