Discount Points - Any points in addition to the loan origination fee are called "discount points." On a conventional loan, discount points are usually lumped in with the loan origination fee.
Appraisal Fee - Your property is your collateral for the mortgage, so lenders want to be reasonably certain of the value and require an appraisal. Appraisal fees vary.
Credit Report - Required by your mortgage lender. Fees vary.
Lender's Inspection Fee - Required by your mortgage lender if you’re buying a new home. Fees vary.
Mortgage Broker Fee - Applies only if you work with a mortgage broker. Fees vary.
Tax Service Fee - Required by your mortgage lender. Fees vary.

Items Required To Be Paid In Advance
Pre-paid Interest - Since mortgage loans are usually due on the first of each month, this fee is based on the number of days the closing takes place prior to the first of the following month.
Homeowner's Insurance - Typically, you will pay the first year in advance. fees vary.
VA Funding Fee - The Veterans Administration sometimes charges a fee for guaranteeing your loan. Fees are normally added to the balance of the loan.
Up Front Mortgage Insurance Premium (UFMIP) - This is charged on FHA purchases of single family residences (SFR's) or Planned Unit Developments (PUDs) and is 2.25% of the loan balance. Like the VA Funding Fee it is normally added to the balance of the loan.
Mortgage Insurance or PMI - Most mortgage insurance (if required) is paid monthly with your mortgage payment. PMI covers the lender and a portion of the losses in cases where borrowers default on their loans.
Reserves Deposited with Lender - The lender's goal is to always have sufficient funds to pay your bills as they come due. Here, if you make a minimum down payment, you may be required to deposit funds into an impound account to make the payments on your homeowner's insurance, property taxes, and mortgage insurance. Impound accounts are sometimes referred to as escrow accounts.
Homeowners Insurance Impounds - Since a lender is allowed to keep two months of reserves in your account, you will have to deposit two months into the impound account to start it up.
Property Tax Impounds - Here, the amount varies depending on when your closing takes place. Fees vary.
Mortgage Insurance Impounds - Most lenders ask that you may put at least one, possibly, two months worth of mortgage insurance as an initial deposit into your impound account.
