Before you overpay
- Check your lender's early repayment charges (ERCs) -- many fixed-rate deals limit overpayments to 10% of the balance per year
- Build an emergency fund first -- once overpaid, you can't easily get the money back
- Pay off higher-interest debts (credit cards, loans) before overpaying your mortgage
