You can start shopping for your mortgage renewal as early as 120 days (about four months) before your maturity date — even before your current lender sends you a renewal offer. Lenders are only legally required to send that offer 21 days before your term ends, which doesn’t leave much time to compare options if you wait for it.
The renewal rate your current lender offers first is often not their best rate — it’s frequently based on posted rates with a modest “discount” designed to feel like a deal. Starting early gives us time to shop the full market on your behalf and bring you a genuinely competitive offer, rather than whatever shows up in your mailbox.
