Get an 80/20 1st & 2nd with no money down (you still need to bring in money for closing costs). This avoids mortgage insurance you would have to pay if you were to get the 100% financing 1st and also the huge fees your broker is trying to charge you. When you sell your current house you then pay off the 20% 2nd loan on the new house.

Who are you talking to about the loan? I'd suggest calling a lot of lenders and getting different quotes. Different credit checks during a short period of time for the same thing do not negatively effect your credit more than the 1st credit check did.
