No one can predict with certainty how interest rates will evolve. However, 2026 remains a pivotal period to:
- Buy your first home or a new property
- Build your dream house
- Renegotiate an existing mortgage on better terms
Principle of the Mortgage Loan
Obtaining a mortgage loan essentially depends on two key ratios carefully examined by lending institutions. The first is the ratio between the value of the property and the amount you wish to borrow, which generally should not exceed around 80%. The difference represents your personal contribution, or own funds. The more own funds you provide, the more reassuring your profile will be for the lender.
The second ratio is the level of your monthly expenses in relation to your household income. As a general rule, the total of your monthly payments, including your future mortgage, should not exceed approximately 33% of your net monthly income. In other words, your mortgage payment should remain limited to about one-third of your income to preserve a comfortable financial margin for daily living expenses and unexpected events.
Before submitting your application, it is wise to calculate your borrowing capacity and simulate different scenarios (term, rate type, amount of own funds). This will allow you to present a coherent and realistic file to your financial institution and to compare offers more objectively.
The Ideal Profile for a Mortgage Loan
Each lender has its own internal credit policy, but some criteria are commonly sought after. A couple with stable employment, both on permanent contracts and contributing at least 20% in own funds, will generally find it easier to obtain financing on attractive terms. This combination reduces the perceived risk for the bank and can open the door to more competitive interest rates.
The existence of additional personal guarantees is also a significant advantage. For example, the absence of ongoing consumer loans, a healthy savings cushion, and a clean credit history are all elements that will be taken into account positively. Conversely, frequent overdrafts or numerous outstanding loans can weaken your application and restrict your negotiating power.
Preparing your project in advance—by consolidating debts where possible, reducing unnecessary expenses and documenting your income and assets—enables you to present yourself as a strong, structured and credible borrower. This is exactly the kind of profile that financial institutions are keen to support over the long term.
Choosing the Best Interest Rate Strategy
Attractive interest rates can sometimes hide other realities: high property prices, increased land values, or tight market conditions. Before committing, take the time to analyse your local real estate market, compare several financial institutions and negotiate every aspect of the offer—not only the rate but also fees and ancillary products.
A fixed-rate loan offers visibility: you know in advance the amount of your monthly payments for the entire duration of the loan. A variable-rate loan, on the other hand, may fluctuate depending on market conditions and can reserve both good and bad surprises. The choice largely depends on your risk tolerance, your financial culture and your repayment capacity.
Intermediate solutions also exist, such as mixed formulas combining fixed and variable rates. Do not overlook ancillary products such as outstanding balance insurance, which can protect you and your loved ones in the event of death, incapacity for work or disability. A global approach to your financial protection is often more relevant than focusing solely on the nominal rate.
Fixed Rate
Stable and predictable monthly payments for the entire term of your loan. Ideal if you want security and long-term visibility on your budget without exposure to rate increases.
Variable or Mixed Rate
Potential benefit from rate decreases, with a higher risk in the event of increases. Suitable for borrowers with solid repayment capacity and a greater tolerance for fluctuations.
Protection & Insurance
Outstanding balance insurance and other ancillary products can secure your project in case of unforeseen events. They are a key element to discuss when structuring your mortgage package.
Managing Repayment Difficulties
Over a 20- or 30-year period, it is possible to encounter financial difficulties linked to life events such as job loss, illness, separation or unexpected expenses. Anticipating these situations and knowing the available options allows you to react quickly and limit the impact on your finances and your credit history.
Requesting a renegotiation of your initial rate can help reduce your monthly payments, especially if market conditions have evolved in your favor. This approach may involve fees, but it can generate significant savings over the long term if correctly negotiated and adapted to your situation.
In the event of a temporary difficulty, your lender may grant a suspension of capital repayment for a defined period, during which you may only pay interest. This provides short-term relief while allowing you to regularize your situation without immediately modifying the total duration of the loan.
Extending the duration of your loan is another solution to reduce monthly payments. This spreads the capital over a longer period, lowering the financial pressure each month, but may increase the total cost of the credit. It is therefore important to weigh the advantages and disadvantages with a professional adviser.
