Sir, your mortgage balance stands at £171,073 with payoff tracking for November 2040, representing a robust seven years and eight months ahead of the original contract. The £250 monthly overpayment has already yielded £25,663 in interest savings against £8,763 deployed, though the ten-year overpay versus invest analysis suggests capital deployed to equities would generate £16,041 in profit versus £7,880 in interest savings—a meaningful £8,161 differential favouring investment. Your 57.2% equity position is healthy and your rate holds until July 2027, at which point refinancing optionality emerges. The signal here is clear: you've built enough cushion that future contributions warrant allocation toward growth rather than acceleration of an already-disciplined repayment schedule. Systems nominal. Ready for July 2027 rate review protocol.
