How can I get out of these year lease without any problems?

I have been living in my duplex for a year in a half. Back in Feb. we signed out second year lease with them. We have very good tenants, always paying rent on time. We have never given them any problems what so ever. Well my husband just got another job for better money and we need to move. We have no problem paying July's rent and them keeping the deposit. I am very stressed that they will expect us to pay the rest of the rent on the lease which is 7 months. I'm not sure what to do. This wasn't planned, it just whats come up. IS there any way to get out of this lease without repercussions??
