Statutory costs are expenses you would have to pay to state and local agencies even if you paid cash for the house and did not need to take out a mortgage.
The major portion of other up-front expenses is the deposit or binder you make at the time of the purchase offer and the remaining cash down payment you make at closing.
Mortgage lenders are required to give you a Truth in Lending (TIL) statement containing information on the annual percentage rate, the finance charge, the amount financed, and the total payments required.
