The tax credit expired on April 30th, so this will not affect your upcoming transaction. If you did indeed find a local agent to represent you, I would suggest contacting him as soon as possible to make sure he is able to be part of the transaction. If you have already found your dream home though another agent, your agent may not be honored by the other agent and you may actually not get the representation that you want. Representation, at least here in Ohio is a tricky thing, so for your sake, make sure you get someone to represent your best interests. Good luck.
