<prompt> Human: Recently got married, taking a fresh look at our combined finances for 2018. We have 2 mortgages, car payments and student loans. My inclination tells me to put any of our extra money into paying down my wifes student loans since it has the highest interest rate of our loans. Other than interest rate ... are theyre other factors I should be mindful of when deciding what to start paying down first?  <response>: You will save the most money by concentrating on the interest rate.Some people like to pay off smallest loans first so they get the morale boost of seeing fewer loans, and some cash flow benefit as well.
