Mortgage rates 2026: why the loan rate will be decisive

The mortgage rates 2026 outlook is the central parameter in any buy or rent decision. In 2024‑2025, average mortgage rates in the euro area are around 3.5 to 4% for 20‑year loans, after peaking above 4.5% in 2023. For 2026, the key question is not just whether rates will go up or down, but rather: how does a 1‑point change in the loan rate affect my total cost?

On buy-or-rent.net (acheter-ou-louer.com in French), the taux_pret / loan rate parameter lets you test this impact precisely. A 0.5‑point difference can mean tens of thousands of euros over the life of a mortgage. Understanding these magnitudes is essential before you decide whether to buy or rent.

Where are mortgage rates before 2026?

To think about mortgage rates 2026, start from recent figures:

This rapid rise has already changed the answer to the question "buy or rent?" for many households. Buying the same property with a 1% loan rate or a 4% rate does not produce the same monthly burden or the same return compared with investing in a diversified ETF portfolio.

Mortgage rates 2026: three numerical scenarios

Rate forecasts are never guaranteed, but we can build working scenarios and test them in the buy or rent simulator by adjusting the taux_pret / loan rate parameter.

Scenario 1: stabilization around 3.6%

Assume an average 3.6% rate for 20‑year mortgages in 2026, close to current levels.

Using the standard annuity formula, we get approximately:

In this scenario, the buy or rent comparison depends mainly on:

Scenario 2: rates easing to 2.5%

Now imagine rates fall back in 2026 to around 2.5% for 20‑year loans.

Result:

Compared with the 3.6% scenario:

With mortgage rates 2026 at 2.5%, buying becomes mechanically more attractive in the buy or rent comparison, if property prices do not surge at the same time.

Scenario 3: rates climbing back to 4.5%

Finally, assume a tighter rate environment in 2026, with an average mortgage rate of 4.5% on 20 years.

We obtain:

Compared with 2.5%, the monthly payment is higher by about €280, and total interest by more than €67,000. In such a context, the answer to "buy or rent in 2026?" becomes much less obvious and depends more heavily on your life plans (how long you will stay, job mobility, family situation).

How the loan rate shapes the buy or rent calculation

In the buy-or-rent.net simulator, a default taux_pret / loan rate of around 3.6% is often used, and you can change it freely. When you adjust this parameter, several things change:

Take a household that can allocate €1,500/month to housing costs (excluding charges):

The level of mortgage rates 2026 will therefore influence not only your monthly payment, but also the type of property you can realistically buy (size, neighborhood), and thus the true comparison between the property you could own and the one you would rent.

Mortgage rates 2026 and other costs you must factor in

The loan rate is only one part of the equation. Even if we focus on the taux_pret parameter, the overall cost of buying also depends on other items that you can (and should) enter into the simulator.

Borrower insurance

The insurance rate (often between 0.25 and 0.45% of the capital per year) is added on top of the nominal loan rate.

In a 2026 environment where mortgage rates are stable or slightly falling, optimizing insurance (switching providers, negotiating coverage) can have an impact comparable to a few tenths of a point on the loan rate itself.

Notary and agency fees

For a €300,000 existing home, it is common to reach €25,000–30,000 in upfront transaction costs (notary + agency). These amounts are not directly affected by mortgage rates 2026, but they do extend the time needed for buying to become more attractive than renting.

Property tax and reassessments

Property tax can range from a few hundred euros to more than €5,000 per year depending on the city, with frequent annual reassessments that may outpace inflation. If you pay €1,200 in property tax in year one and it increases by 3% per year on average, you will pay around €2,170 per year after 20 years.

Even if mortgage rates 2026 are low, a strong upward trend in property tax and maintenance costs can offset part of the financial advantage of owning.

Full example: buy or rent in 2026 with different rates

Consider a household in 2026 hesitating between buying and renting an equivalent apartment:

Case 1: mortgage rates 2026 at 2.5%

With taux_pret = 2.5%:

The monthly cost is close to the rent, but part of each payment builds equity. If the household stayed a tenant, they could invest the €40,000 down payment plus any monthly savings at 4%. In the simulator, buying often becomes more favorable after roughly 10–15 years under these assumptions, assuming flat real estate prices.

Case 2: mortgage rates 2026 at 3.6%

With taux_pret = 3.6%:

The monthly effort is now €180 higher than the rent. The opportunity cost of not investing this extra €180/month at 4% becomes significant. In many simulations, the break‑even horizon where buying overtakes renting may move beyond 15 years, depending on rent indexation and property value growth.

Case 3: mortgage rates 2026 at 4.5%

With taux_pret = 4.5%:

The gap versus rent reaches €300/month. If the household chooses to rent, they can invest the initial €40,000 plus these €300/month at 4% per year. After 20 years, the accumulated capital can rival, or sometimes exceed, the net equity they would have built as owners, especially if property prices stagnate.

This example shows how changing only the loan rate can flip the result of a buy or rent analysis, even when all other parameters remain the same.

Using the simulator to test your 2026 rate scenarios

On buy-or-rent.net, the taux_pret / mortgage rate field is fully customizable. A practical way to use it is:

At the same time, adjust:

This gives you a quantified view of the impact of mortgage rates 2026 on your buy or rent decision, instead of relying on a single macroeconomic forecast.

Caveats and limits of rate forecasts

Forecasts for mortgage rates 2026 depend on many moving parts: central bank policy, inflation trends, growth prospects, banking regulation and credit risk. No one can guarantee an exact level two years ahead. It is therefore prudent to:

If rates fall after you buy, you may be able to refinance, but refinancing has costs (prepayment penalties, new fees, potential new collateral costs). The simulator lets you approximate the benefit by comparing your current rate with a hypothetical lower mortgage rates 2026 scenario.

Conclusion: mortgage rates 2026 and the buy or rent decision

Mortgage rates 2026 will be a key input in your decision, but not the only one. For the same property, a 1–2 point difference in the mortgage rate can dramatically change the result of a buy or rent comparison, especially if you correctly account for:

The most robust approach is to simulate multiple taux_pret scenarios (2.5%, 3.6%, 4.5%, etc.) side by side, while also adjusting rent growth, inflation, investment returns and property tax increases.
