Would you do a 2 year lease for you first ever rental?

[Jacqueline Blue]

My husband and I are renting out first place (yay!). We have a few people lined up to see the place. But one of the best potential tenants on paper asked if we would do a 2 year lease for a slightly reduced rent. 
they are moving to our state, one person has a job here and is already working for said company, amazing credit and no debt at all. The other person (their partner) is starting a new career and so doesn’t really make any money. But the first person make enough to cover the rent and then some. 
I guess my question is would you all do a two year lease for for very first lease. Or are we getting in to trouble? All stories, thoughts, and feeling are welcome. 
Thanks for your time.
