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

Some lenders require 20 percent of the home's purchase price as a down payment. However, many lenders now offer loans that require less than 20 percent down—sometimes as little as 5 percent on conventional loans. If a 20 percent down payment is not made, lenders usually require the home buyer to purchase private mortgage insurance (PMI) to protect the lender in case the home buyer fails to pay. When government-assisted programs such as FHA (Federal Housing Administration), VA (Veterans Administration), or Rural Development Services are available, the down payment requirements may be substantially smaller.

• Ask about the lender's requirements for a down payment, including what you need to do to verify that funds for your down payment are available.
• Ask your lender about special programs it may offer.

If PMI is required for your loan,

• Ask what the total cost of the insurance will be.
• Ask how much your monthly payment will be when including the PMI premium.
• Ask how long you will be required to carry PMI.

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).
