How can you make sure your rate is low?

There are many ways to get a lower rate. A larger down payment will result in a lower interest rate rather than a smaller one; this is because you're starting out with more equity. You can pay points to lower your rate over the life of the loan, but that means you pay more up front. For many people, this makes sense and is a good deal.

Closing costs are fees paid by the lender, which the lender in turn charges you to close the loan. Many people pay closing costs when they sign on the dotted line, but many finance their closing costs. Paying closing costs when the loan closes will reduce your interest rate.

Finally, the interest rate a lender is willing to offer you depends on your credit score and your income-to-debt ratio. If you have good credit and your income far exceeds your debt obligations, you will qualify for a lower rate.
