I commend you on your decision to want to purchase a home. It's a great time to do so in many areas since home prices have come back down to reality.
I highly recommend that you shop around to find a good quality lender that you trust and feel comfortable with. And of course they should really know what they're doing since so many changes have been made the last year or so.
Perhaps you could ask some of your friends, co-workers, etc as to whom they would recommend based on their own recent experiences. If they had a great lender, then should be eager to want to refer you to them.
You could do the same in order to find a great Realtor as well.
