Lower interest rates are a primary motivation for refinancing a mortgage, which can reduce monthly payments and total interest costs over the life of the loan. However, there are other valid reasons for refinancing beyond lower rates. Refinancing may allow homeowners to pay off their loan sooner by shortening the term, or take advantage of lower variable interest rates. Refinancing can also provide access to equity in the home through a cash-out refinance. The best options depend on an individual homeowner's priorities and financial situation.
