Why your renewal offer is rarely the best rate
When your term ends, your current lender sends a renewal offer — a rate and term you can accept by signing. It's convenient, and that's exactly the point: lenders know most borrowers sign the first number without shopping, so the opening offer is frequently above what the same lender would give a client who threatens to leave, and above what a competing lender would post to win new business. You're not being treated unfairly; you're being counted on to stay put.
Switching lenders at renewal breaks that pattern. Because your term has ended, you can move your mortgage to a different lender with no prepayment penalty, and a competing lender treats you as a fresh client worth sharpening a rate for. The result is often a materially lower rate than your renewal letter — which, on a meaningful balance, can translate into real savings over the term. The only reliable way to know is to compare your offer against the wider market before you sign, ideally across many lenders at once.
