📖 Mortgage renewal guide: start six months out

Renewal is a negotiation, not a formality

When your mortgage term ends, the balance comes due in law — and in practice, your lender offers to renew it. That renewal offer, which typically arrives a few months before maturity, is an opening bid, not a final price. Lenders know most borrowers sign it unread: industry surveys consistently show a majority of renewals happen with the existing lender, often at the first rate offered. The borrowers who treat renewal as a six-month project instead of a signature tend to pay less for the next five years. This guide is that project, in order.

The timeline

Six months out: note your maturity date, your current balance, and your remaining amortization. Check your prepayment and portability terms. Start a folder — renewal is paperwork season. Four months out: most lenders allow an early renewal roughly 120 days before maturity without penalty, and rate holds typically run 90 to 120 days, so this is when you collect real quotes: your lender's early-renewal offer, at least one competitor or broker quote, and today's best insured/insurable rates for comparison. Two to three months out: negotiate with the competing quote in hand, or start a switch application — a switch involves a new application, documents, and usually an appraisal, and your new lender often covers transfer costs. The final month: if you do nothing, many mortgages roll into an open term or the offered rate by default, which can be the most expensive outcome on the table. Doing nothing is also a decision; make it deliberately.

The payment shock, in real numbers

The 2025-2026 renewal wave is defined by one piece of math. Take a $400,000 balance with 20 years of amortization remaining, renewing from a pandemic-era 2.00% to 4.49%. At 2.00% the payment is $2,022 a month. At 4.49% it is $2,520 a month — $498 more, every month, or about $5,976 a year. (These are this site's payment engine's own figures, the same example used on the renewal hub; run your own balance through the payment calculator.) Three honest ways to soften a shock like that: extend the amortization back toward 25 or 30 years if you qualify, which trades a lower payment now for more interest over the life of the loan; make a lump-sum prepayment before renewal, since a smaller balance means a smaller payment at any rate; or some blend of both. What does not soften it is ignoring the letter until the month it lands.

Switching lenders got easier — the stress-test relief

Until recently, switching lenders at renewal meant re-qualifying under the federal stress test at the higher of 5.25% or your new rate plus 2%, even though you had been paying the mortgage for years. A late-2024 change removed that hurdle for straight lender switches at renewal — where the loan amount and amortization stay the same — for many borrowers. It applies to many, not all: changing the balance or amortization, or certain insured situations, can still trigger full qualification, so confirm your case with the lender or insurer involved. The practical effect stands: if your lender's renewal offer is lazy, the exit door is wider than it used to be, and your lender knows it. If instead you want to change the loan itself — borrow more, extend amortization, consolidate debts — that is no longer a renewal but a refinance, with its own math in the refinance calculator.

Reading the renewal offer like a contract (because it is one)

When the offer arrives, read past the headline rate to the four terms that decide what the next term actually costs. Prepayment privileges: the lump-sum and payment-increase room (see the penalties guide) — a rock-bottom rate with thin privileges is a worse product for anyone planning lump sums. Portability: whether the mortgage can move to a new property, which matters if a move is even a maybe in the next five years. Penalty type: fixed-rate renewals carry IRD exposure, variable renewals carry the gentler three-months-interest calculation — the rate gap between fixed and variable offers should be weighed against that difference in exit cost. Collateral versus standard charge: some renewals quietly re-register the mortgage as a collateral charge, which can make a future switch to another lender require a legal refinance instead of a simple transfer — ask explicitly, because it rarely appears in the marketing summary. And one question worth asking out loud on the phone: "Is this your best rate for a client with my payment history, or your first offer?" Renewal offers are priced expecting a negotiation; the discount for asking is frequently a tenth or two of a percent, which on a $400,000 balance is roughly $2,000 of interest over a five-year term — real money for a five-minute question.

Penalties and early renewal: handle with care

At maturity itself, there is no penalty — the term is over. Penalties only enter if you break before maturity, including some "early renewal" offers that quietly blend your old and new rates. Any penalty figure a lender quotes before the fact is an estimate that moves with rates; the only number that counts is the one in writing for a specific payout date. The prepayment penalties guide explains how those numbers are built (3 months' interest versus the interest rate differential) so you can sanity-check any quote you are given. Renewal season is also the moment to reset your prepayment strategy for the new term — the prepayment calculator shows what an extra $200 a month does from day one of the new term, not as an afterthought.
