There are a number of reasons why you should consider mortgage refinance. This includes to get a better mortgage deal. For example, are their interest rates available that are lower than you currently pay?
You might have a penalty clause with your current lender, i.e. if you break the terms of the mortgage by closing it early you’ll be charged a fee. Even with this fee, however, you might still be able to save money in the long-term if you refinance.
