@antonia_investing: Should you overpay your mortgage or invest the money? There is no universally correct answer. But there are some useful questions to work through. The maths: overpaying a mortgage at 4.5% gives you a guaranteed, tax-free 4.5% return. For comparison, the FTSE All-World index has delivered a nominal annualised return of around 7 to 8% a year over the last 20 years, gross of inflation and before charges. That is a long-run historical figure, not a guarantee, and returns vary significantly depending on timing and individual circumstances. Some questions worth considering: How close are you to your fixed rate ending? If you may need access to cash in the near term, that is relevant to whether committing to longer-horizon investments makes sense right now. What is your mortgage rate? The lower your rate, the wider the potential gap between it and long-run investment returns. The higher your rate, the more attractive the guaranteed saving from overpaying becomes. Where that balance sits depends on your time horizon, risk tolerance, and personal circumstances. Have you used your ISA and pension allowances? The tax efficiency of those wrappers is worth considering before either option. The psychological dimension matters too. The financial value of reduced stress and better decision-making is real, even if it doesn't appear in a model.

Past performance is not a reliable indicator of future results. Mortgage overpayment terms vary by lender. Any decision should take into account your individual circumstances, objectives, and attitude to risk. Speak to an FCA-regulated financial adviser before making significant financial decisions.
