Hi Everyone, I am a new member here

I have a decision to make. This year I had to sign a lease with my old apartment/landlord for a higher rent than before as prices have gone up. My lease started from Jan2012 and ends in Dec2012. So its for 1 year.
I saw that a nearby landlord is providing an apartment where the rent/month is 100$ less than what I am paying with the same facilities. I would like to book this new apartment but don't want to break the current lease and go for it now.
I was planning to book this new apartment from Jan2013 for a year. As the specials the landlord is offering are better. (The apartment does not look so nice as my current one).
Is this a good decision? What do you think? I need someone's advice..
Thanks
