would you?

Teacher, are both sentences OK? I think both are correct. I see more people using no. 2.

1) Mike is having a party at his house on May 2, 2013. Are you available to attend?

2) Mike is having a party at his house on May 2, 2013. Would you be available to attend?

They are both correct.

As an NES but not a teacher, both are fine by me.
Unless very formal, I'd probably leave out "to attend" and replace "available" with "free".

I find the use of "available to attend" very formal. If you're friendly enough with someone to invite them to a party at someone else's house, I would expect something like:

Mike's having a party on May the second. Can you come?
Mike's having a party at home on May the second. Are you free?
