A stranger is joining my band, what should I do with her and how to make this comfortable for everyone?

So me and my friend are making a band. Up to now we just go over to each others house and just practice a little, maybe jam sometimes. we both play the guitar. So today, I found a singer. But she is still a complete stranger to me. I met her thru facebook, and Ive only talked to her once, about this. So I messaged her because I had seen her name in a friend's friend list, and the name was perculiar, so it caught my attention. Then, with that name, I found out we take lessons with the same guitar teacher (her name was written separately on pen on the teacher's sheet, which every student has to sign). So she is gonna decide if she wants to join. She was enthusiastic, just, you know, nobody can make that kind of compromise in a minute. But if she does, I dont kmow what to do. I mean, yeah, we should practice somewhere, but where? Its not like (i think) she can go into a strangers house to practice. And idk, its all filled with awkwardness.
