Sounds like a good move, for many reasons.
A word of caution, though - in addition to your rental contract with your landlord - whichever way you choose to go - it's a very good idea to have a contract between yourselves as well. It's easy to say, "But we're all friends, we'll be fine," but things
can go wrong, and friendships
can sour, sadly.
Something simple to include when the rent contributions have to be in by, how much notice any of you needs to give the others before leaving the yard, who's responsible for what, etc.
Best of luck!
