Tips to Get the Lowest Mortgage Interest Rate

It's important to shop around for mortgage loans as lenders have different loan programs. To reduce your rate, you may choose to pay points. Generally paying one point (or 1% of the loan) will reduce your mortgage rate by 0.25%. Improving  your credit score can reduce your mortgage rate. If you don't think rates will rise, wait to lock in your rate as lenders charge slightly higher rates for longer lock-in periods.
