Mortgage rates 2026: trends, scenarios and impact on your loan

Mortgage rates 2026: why they are central to your buy or rent choice

The mortgage rate is the most sensitive variable in any home-buying plan. In 2024–2025, rates in the eurozone have stabilised around 3.5–4% for 20 years for solid profiles, after peaking above 4%. For 2026, the key question is: will rates fall, stay flat or rise again?

The answer is uncertain, but the impact is very concrete: between a 3.6% and a 2.5% rate, the total interest cost can differ by more than €40,000 over 25 years for a typical borrower. This is exactly what the taux_pret (loan rate) parameter in our buy or rent simulator is designed to capture.

This article looks at possible trends for mortgage rates 2026, with data-driven scenarios and practical examples, and shows how they affect the decision to buy or rent. It is not personalised financial advice, but a framework to help you use a tool like buy-or-rent.net more effectively.

Where are mortgage rates now, before 2026?

To think about 2026, you need to start from today’s environment:

• Average rate 2024–2025: around 3.6% over 20 years for good profiles, sometimes 4% or more for riskier borrowers.
• Borrower insurance: often between 0.25% and 0.45% of the loan per year, which adds roughly 0.3–0.4 percentage point to the effective rate.
• Inflation: easing back towards 2–3% after peaks above 5%, which shapes central bank decisions and bank funding costs.

Concretely, a household borrowing €250,000 over 25 years at 3.6% gets a monthly payment (principal + interest, no insurance) of roughly:

• €1,268 / month
• Total interest over 25 years: about €130,000

At 1.5% (levels seen in 2021), the same loan would have cost about €1,000 / month, with total interest closer to €50,000. The roughly €80,000 gap illustrates why the loan rate is central in any buy or rent calculation.

Mortgage rates 2026: three realistic scenarios

No one can predict mortgage rates 2026 with certainty, but you can build reasonable scenarios based on:

• inflation and central bank policy,
• bank risk appetite and funding costs,
• the health of the housing market.

Scenario 1: moderate decline in rates (2.8–3.2%)

In this case, inflation stabilises around 2%, the ECB cuts its key rates gradually, and banks pass part of that through to mortgages.

Assumption: 3.0% mortgage rate in 2026 over 25 years for a strong borrower.

On a €250,000 loan over 25 years:

• At 3.6%: monthly ≈ €1,268, total interest ≈ €130,000.
• At 3.0%: monthly ≈ €1,186, total interest ≈ €105,000.

Difference: about €82 less per month and roughly €25,000 interest saved over the term.

Impact on the buy or rent question:

• Lower rates make buying more attractive over the long run.
• But prices may stabilise or rise slightly again, offsetting part of the benefit.
• You still need to compare this with the return you could get by investing your savings instead of locking them into a property.

Scenario 2: stable rates (3.3–3.8%)

In this scenario, mortgage rates 2026 remain close to 2024–2025 levels:

• Loan rate: around 3.5–3.6% over 20–25 years.
• Insurance: still 0.25–0.45%, meaning an effective annual percentage rate often near 4%.

For our typical household (€250,000, 25 years at 3.6%):

• Monthly payment: €1,268.
• Total interest: ≈ €130,000.

Here, the buy or rent decision depends more on:

• the annual rent increase (linked to inflation indices),
• the return on investments if you remain a tenant (investment rate),
• property tax and its annual reassessment,
• closing costs and any renovation budget.

The loan rate (taux_pret) still matters, but it no longer changes the answer by itself.

Scenario 3: rates rise (4% and above)

In this scenario, inflation resurges or central banks tighten more, banks increase their margins, and mortgage rates 2026 move higher.

Assumption: 4.2% mortgage rate over 25 years.

For a €250,000 loan:

• At 3.6%: monthly ≈ €1,268, interest ≈ €130,000.
• At 4.2%: monthly ≈ €1,348, interest ≈ €155,000.

Difference: roughly €80 more per month and about €25,000 extra interest.

In that environment, renting can stay competitive for longer, especially if:

• rents grow only moderately,
• you can achieve a decent investment rate (e.g. 3–5% per year in diversified funds),
• you expect to move again within a few years (you pay the highest share of interest in the early years).

This is exactly the sort of case where a buy or rent simulator lets you test different loan-rate values (3.5%, 4%, 4.5%) and see at which point buying stops making sense over your chosen horizon.

Worked example: how the 2026 mortgage rate changes the picture

Let’s take a concrete example to visualise the impact of mortgage rates 2026 on the buy or rent decision.

Initial assumptions

• Purchase price: €300,000 (existing property).
• Down payment: €30,000.
• Loan amount: €270,000 over 25 years.
• Closing costs (notary etc.): about 8% ≈ €24,000.
• Equivalent rent today: €1,150 / month.
• Annual rent increase: 2% / year.
• Property tax: €1,200 / year, rising 2% annually.
• Investment return if you rent: 3% / year net on your savings.

We compare three possible mortgage rates in 2026: 3.0%, 3.6% and 4.2%.

Scenario A: 3.0% mortgage rate

• Monthly payment for €270,000 over 25 years at 3.0%: ≈ €1,280.
• Total interest: ≈ €113,000.
• Insurance (0.30%): ≈ €675 / year, or about €56 / month.

Owner’s monthly outlay (excluding maintenance and service charges):

• €1,280 mortgage + €56 insurance + €100 property tax (1,200/12) ≈ €1,436 / month in year one.

Compared with rent of €1,150, you pay about €286 more per month, but:

• part of that payment builds equity,
• rent rises by 2% per year, reaching roughly €1,700 / month after 15 years,
• property tax also increases, though from a lower base.

Scenario B: 3.6% mortgage rate

• Monthly payment for €270,000 at 3.6% over 25 years: ≈ €1,370.
• Total interest: ≈ €135,000.
• Insurance: still ≈ €56 / month.

Owner’s monthly outlay:

• €1,370 + €56 + €100 ≈ €1,526 / month.

Gap vs rent: about €376 / month in year one, or roughly €4,500 per year. Buying can still win over the long term, but the breakeven point in a buy or rent simulation moves further into the future.

Scenario C: 4.2% mortgage rate

• Monthly payment for €270,000 at 4.2% over 25 years: ≈ €1,460.
• Total interest: ≈ €158,000.
• Insurance: ≈ €56 / month.

Owner’s monthly outlay:

• €1,460 + €56 + €100 ≈ €1,616 / month.

Gap vs rent: about €466 / month in year one, or more than €5,500 per year. In this case, remaining a tenant and investing the difference at a decent investment rate can remain competitive for many years, depending on how rents and property prices evolve.

These figures show how strongly the taux_pret (mortgage rate) reshapes the economics of buying versus renting in 2026.

How to factor 2026 mortgage rates into your strategy

1. Don’t base your entire plan on rate forecasts

No one knows exactly where mortgage rates 2026 will land. What you can do instead is:

• test several loan-rate assumptions (for example 3%, 3.5%, 4%),
• observe how the buy or rent breakeven moves,
• identify your safety margin: up to what rate does buying still make sense for you?

2. Look at the full APR, not just the headline rate

The nominal loan rate is only one part of the cost:

• Borrower insurance: typically adds 0.25–0.45 percentage point.
• Fees and guarantees: increase the effective cost over the life of the loan.
• Closing costs: 7–8% in existing stock, 2–3% in new builds.

A 3.4% mortgage with expensive insurance can be worse than a 3.6% loan with optimised insurance. In a buy or rent simulator, you should set the taux_pret in line with your overall APR, not just the nominal rate seen in marketing materials.

3. Combine mortgage rates with other critical parameters

For 2026, the buy or rent decision also depends on:

• Annual inflation: it erodes the real burden of fixed mortgage payments, but also erodes the real value of cash if it’s not invested well.
• Rent indexation: a rent that rises by 2–3% per year becomes very expensive over 20 years.
• Property tax and reassessment: in some cities, taxes have jumped by more than 20% in just a few years.
• Investment returns: if you can reliably earn 4–5% per year over the long term, staying a tenant and investing the difference can be rational, especially with high mortgage rates.

The taux_pret parameter therefore needs to be analysed together with these other factors, not in isolation.

Using a buy or rent simulator with 2026 mortgage rate scenarios

Rather than chasing the “perfect timing”, it is usually more useful to simulate several scenarios:

• Optimistic: mortgage rate at 3.0%.
• Base case: 3.6%.
• Cautious: 4.2%.

On buy-or-rent.net, you can:

• adjust the taux_pret parameter to each scenario,
• see the impact on monthly payments and total interest,
• compare your net wealth after X years if you buy versus if you rent and invest the savings.

In a few minutes, you will see at which mortgage rate 2026 buying starts to outperform renting for your assumptions, and where the opposite becomes true.

Conclusion: 2026 will be important, but the answer remains “it depends”

Mortgage rates 2026 are likely to be lower than the 2023 peak, but there is no guarantee of a return to the ultra-low levels of 2021. Between a 3.0% and a 4.2% loan, the difference in cost over 20–25 years is substantial and can flip the result of your buy or rent analysis.

There is no universal answer: everything depends on how long you plan to stay, your risk tolerance, your borrowing capacity, and the investment returns you can realistically achieve. Parameters such as the loan rate, rent inflation, property tax and general inflation all need to be considered together.
