Should I pay off the mortgage faster, or use that extra cash to invest? This is a very common question, but it’s especially relevant today. Mortgage rates are at 15-year highs, with borrowing costs at levels many homeowners won’t have experienced before. Paying down the mortgage as quickly as you can is sensible, and it’ll set you on the path to financial freedom. However, it’s not black or white and using some of that spare money to invest along the way will also pay off.
