Quick context
Read full guide: UK Mortgages Explained →- LTV (loan-to-value) is the biggest lever on your rate — every 5% lower band can cut 0.1–0.4 percentage points.
- Overpaying early kills interest hardest because the loan compounds; the same overpayment in year 20 saves a fraction.
- Mortgage vs invest: invest if rate < ~3.5%, prepay if > 5%, coin-flip in between — and emergency fund + employer match come first.
