The origination fee (also called underwriting fee, administrative fee, or processing fee) is charged for the lender’s work in evaluating and preparing your mortgage loan. This fee can cover the lender’s attorney’s fees, document preparation costs, notary fees, and so forth.

Estimated cost: 1% to 1.5% of the loan amount

If your home is in a flood hazard area where federally subsidized flood insurance is available, lenders cannot make a mortgage loan for your home unless you buy flood insurance. Your lender may charge a fee to find out whether the home is in a flood hazard area.

Estimated cost: $15 to $50 (this is not the cost for the flood insurance; flood insurance, if required, would be in addition to your homeowners insurance and may cost from $350 to $2,800 depending on location and property value)

Your first regular mortgage payment is usually due about 6 to 8 weeks after you settle (for example, if you settle in August, your first regular payment will be due on October 1; the October payment covers the cost of borrowing the money for the month of September). Interest costs, however, start as soon as you settle. The lender will calculate how much interest you owe for the part of the month in which you settle (for example, if you settle on August 16, you would owe interest for 15 days--August 16 through 31).

Estimated cost: Depends on loan amount, interest rate, and the number of days that must be paid for (a $120,000 loan at 6% for 15 days, about $300; a $142,500 loan at 6% for 15 days, about $356).
