With that being said, here’s a basic guide on when to refinance a home loan, from a financial standpoint:

Switching from an ARM to a fixed rate — This is a common reason why homeowners pursue a refi in the first place, especially with all the negative press the adjustable rate mortgage (ARM) loan has been getting lately. Eventually, an ARM will adjust to a higher interest rate that catches a lot of homeowners off guard. So many people use refinancing as a way to move to a more predictable fixed-rate mortgage.
Capitalizing on Lower Interest Rates — This is another common reason why people refinance their home loans. When the rates are low, homeowners in certain situations can refi to a lower interest rate, and thus reduce their overall monthly mortgage payment.

Mortgage refinancing in 2010 is a good thing for many people to do. However, all situations are unique and will require a different approach. Know what you need to do and research as much as you can about it.
