If you have an adjustable-rate mortgage that has crept up over the years, it might make sense to now to lock into a lower fixed interest rate loan. Switching to a fixed rate while interest rates are low will save you thousands over the life of the loan.
Has your home increased in value or have you paid down a significant amount of your mortgage? Take advantage of lower rates and see about removing your PMI through a refinance.
When a much lower mortgage interest rate is available for you to lock, it may be time to refinance into a shorter loan term. You can pay off your loan sooner and save over the life of the loan.
Your mortgage interest rate is often a reflection of your credit rating. If your credit score has improved, there is a chance you qualify for a lower interest rate when you refinance
If you have equity in your home, then a great option for you may be to pull cash out. The money could be used for major renovations, to consolidate high interest debt, or even to help your children pay for college.
