Getting a mortgage loan is a big commitment. Learn about all the variables involved in getting a mortgage and the impact these variables have on your interest rate. Before you refinance, you can find the most common variables that go into calculating estimated monthly payments and interest rates provided here.
Click "Purchase" if you are buying a home. Click "Refinance" if you own a home and you want to replace your mortgage with another loan at a different rate and terms.
Select which type of mortgage you are shopping for: a 30-year fixed-rate loan, a 15-year fixed, an FHA-insured loan, an adjustable-rate mortgage (ARM) with an introductory rate lasting 5 or 7 years, a 20-year fixed, and 10-year fixed or a 30-year Veterans Affairs loan.
Write your estimated property value. The value is defaulted based on your location, but you should enter your own number.
Enter the remaining balance on your current loan.
If you know your credit score, select the range that your score belongs to. The best rates and terms go to borrowers with credit scores of 740 and higher, and borrowers in the 720 to 739 range can get very good deals, too.
Select the range of discount points that you are willing to pay. Discount points are an upfront fee that you pay to get a lower interest rate. One point is 1 percent of the loan amount. On a $100,000 mortgage, if you pay 1 point, you pay an upfront fee of $1,000.
Enter your zip code. You might see a bigger selection if you choose the nearest large city.
Determine how much of your monthly payment will go toward the principal and how much will go towards interest.
