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.

Points are a one-time charge imposed by the lender, usually to reduce the interest rate of your loan. One point equals 1% of the loan amount. For example, 1 point on a $100,000 loan would be $1,000. In some cases--especially in refinancing--the points can be financed by adding them to the amount that you borrow. However, if you pay the points at settlement, they are deductible on your income taxes in the year they are paid (different deduction rules apply when you refinance or purchase a second home). In your purchase offer, you may want to negotiate with the seller to have the seller pay your points.

Estimated cost: 0% to 3% of the loan amount
