If you have not looked into refinancing lately, it might be a good idea. Rates continue to decline, and refinancing could save you a lot of money if you plan to stay in your house for the next several years. The other effect of low interest rates rates is that house prices will continue to increase partially because of that. Homebuyers can afford to spend more on a house as rates drop. Definitely check with your lender, and other lenders. Some allow you to refi with low fees, while other ones cost more money to do. If you have some extra cash you can also use the opportunity to do a refinance with a rate buy down for an even lower rate, or even pay down some of the principle.
