In AZ -normally, the owner pays the title insurnace - the lender needs to disclose the cost to you, but you should see a credit from the seller on this when you see your settlement statement or HUD closing statement. Your agent, lender or Escrow officer can help you confirm this.
The origination fee does seem high - but you may be getting a good rate which may make it worthwhile.
There's a nice internet tool on zillow - Mortgage Marketplace which allows you to enter some general information and then lenders tell you what they can do for you, including rates and loan costs. It is a ncie way to "comparison" shop.
You do want to make sure your lender can perform to your contract terms - specifically your COE date and ensuring their loan documents get to Title well before closing so you don't have any delays. Your Realtor can typically recommed a lender who they have positive experiences with.
Good luck on your new home purchase and welcome to Arizona!
