Any suggestion on how to move out from an apartment?

Hi all,

this is a dumb question I think but I moved in Ireland 2 years ago and I'm not 100% familiar with rent laws here.

So I've been living in this house for 2 years now and my lease is going to expire next month. My landlord wants to renew the rent for 1 year and I said yes and I'm currently waiting for the new contract to sign.

However today I got news that I could have to move out in August due to work reason, since I might have to change city. I think there are 2 solutions now:

1) Tell the landlord I might have to move and ask him to make a contract for 6 months. My fear is that if he disagrees, then he might just avoid sending me a new contract and I'll be without house for 5-6 months (and good luck finding a lease for 6 months in the meantime)

2) Sign the new contract and then, IF I have to move, just send a letter to him, like 30 days before, telling him I'll move out. However my fear is that since the new lease is for 1 year, I'll be forced to pay the remaining 6 months by law (is this even possible?)

Of course option number 2 is better for me but is it feasible legally? Is there any way in Ireland to move out before the term expires without being forced to pay the rest of the lease?

I hope my question is clear. Thanks!
