What are the different types of loans that can be refinanced (e.g. mortgage, auto loan, student loan)?

Different types of loans can be refinanced, including mortgages, auto loans, personal loans, and student loans. The process of refinancing involves taking out a new loan with more favorable terms and using it to pay off the original loan. Refinancing can help borrowers save money by getting a lower interest rate, reducing their monthly payments, or changing the length of the loan term. It can also allow borrowers to switch from a variable rate loan to a fixed rate loan or vice versa.
