Tenants want to renew lease, but might move early - thoughts?

[Allan M.]

Hey everyone -  first post, looking for some advice. It's my first year into being a landlord, and all is going well so far but I have a question about lease renewal. 

The lease for our rental ends at the end of October, then goes month to month. We'd like to keep the tenants in the house, and they'd like to stay. However, one of the tenants is exploring job opportunities that could result in them relocating in January or February. So if they sign a new lease, they said there's a chance they'd have to break it just a few months in. It's also possible that nothing happens and they end up staying in town. 

Should we just recommend this go into month to month mode, and reassess later if they don't move? Or is common practice to allow a lease break if it comes to that? I don't love the month to month instability, but I also don't want to relist it and turn it over yet untill I have to. Appreciate any thoughts!

Why sign a contract if its not going to mean anything? Just go month to month. Its better for you anyway.
