$9k for closing costs??? Lender / Broker Questions

[Account Closed]

So I'm going through escrow right now and realized I'm pretty sure I'm overpaying for the closing costs. I'm being charged $9,071 and through research, it says that it's usually $3.5-7.5k. The house was $90k. Is this too high for closing costs? Should I try to go through another lender? Would it make a difference? How much of a difference does a broker make for a conventional loan in the sense of decreasing interest rate and costs?
