Renegotiating your mortgage: when, how, and why?

In response to fluctuating market interest rates, many borrowers are looking to optimize the total cost of their loans. Renegotiating a home loan is an internal and effective solution to reduce monthly payments or shorten the repayment duration. Discover all aspects of loan renegotiation, from feasibility conditions to associated banking fees, to help you make an informed decision regarding your loan contract.

What is loan renegotiation?

Loan renegotiation, also known as restructuring or modification, is a process that involves requesting your bank or current lender to modify the terms of your initial loan contract. The primary aim of this process is to obtain a more favorable interest rate than the one originally negotiated.

Typically, renegotiation allows for a reduction in the total cost of credit by decreasing the remaining monthly payments, or by maintaining the same payment schedule while shortening the repayment duration. It is an internal operation that does not require switching to a different banking institution. It is governed by an amendment to the initial contract, formalizing the new borrowing conditions.

If rate renegotiation proves to be complex or unsuccessful, the borrower has a much simpler and often very profitable alternative: changing the loan insurance. Thanks to existing laws, you can terminate your group insurance contract to choose another one from an external company, and this can be done at any time and without fees for changing the borrower’s insurance. This process, which is less burdensome than loan renegotiation, allows for substantial savings on insurance costs, thereby reducing the total cost of the home loan.

What are the costs of renegotiating a home loan?

While loan renegotiation is an internal operation, it is not exempt from fees. Your bank will indeed charge you administrative fees for the study and preparation of the amendment to the initial loan contract. These banking fees are generally fixed or calculated as a percentage of the remaining capital owed.

The costs incurred by this process primarily include:

It is essential to negotiate these fees with your bank advisor to maximize the benefits of the operation.

Why renegotiate instead of opting for a credit buyout?

The choice between loan renegotiation and credit buyout often depends on the balance between simplicity and potential savings.

Choosing internal renegotiation with your current banking institution offers a major advantage: the absence of early repayment penalties (IRA).

Unlike a loan buyout by a competing bank, which imposes the payment of these penalties, renegotiation is exempt from this cost.

Furthermore, it generally incurs lower administrative fees and does not require modifying the guarantees associated with your loan (mortgage or surety). It is a quicker and less administratively complex process, which can make the operation overall more profitable, even if the interest rate obtained is only slightly lower than what a buyout offer might propose.

The conditions for renegotiating a home loan

For your loan renegotiation request to be accepted by your bank, several conditions generally need to be met. The lending institution will assess the feasibility of the operation based on the potential savings for the borrower and its own commercial interest.

Key criteria for a rate renegotiation to be considered include:

A good account management and a trusting relationship with your advisor are also major assets.

When to renegotiate your loan?

The ideal time to consider renegotiating your home loan generally falls within the first third of the repayment duration of the loan.

It is during this phase that the burden of interest is the heaviest, making the impact of a rate decrease maximal on the total cost of credit.

For the process to be relevant and profitable, there must be a significant drop in market interest rates compared to the rate stated in your initial loan contract, ideally by at least 1%.

It is also important to act while the remaining capital owed is significant, as the savings achieved on future monthly payments will be proportional to that amount. Regularly monitoring financing conditions is therefore key to seizing the opportunity for a favorable renegotiation with your banking institution.
