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:
- 2021: historically low rates around 1% on 20 years.
- 2023: sharp increase, often between 3.5 and 4.5%.
- 2024‑2025: stabilization around 3.6% (a typical reference in simulations), with spreads depending on borrower profile and country.
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.
- Property price: €300,000
- Down payment: €30,000
- Loan amount: €270,000
- Term: 20 years (240 months)
- Loan rate (taux_pret): 3.6%
Using the standard annuity formula, we get approximately:
- Monthly payment ≈ €1,590 (principal + interest, excluding insurance)
- Total interest paid ≈ €111,600
- Total repaid ≈ €381,600
In this scenario, the buy or rent comparison depends mainly on:
- the return on your savings if you remain a tenant (investment rate),
- the likely evolution of rents (indexation similar to the IRL in France),
- your expected income growth over time.
Scenario 2: rates easing to 2.5%
Now imagine rates fall back in 2026 to around 2.5% for 20‑year loans.
- Same baseline assumptions: €270,000 borrowed over 20 years.
- Loan rate: 2.5%
Result:
- Monthly payment ≈ €1,430
- Total interest ≈ €73,200
- Total repaid ≈ €343,200
Compared with the 3.6% scenario:
- Monthly payment is lower by about €160.
- Total interest drops by about €38,400.
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.
- Loan amount: €270,000
- Term: 20 years
- Loan rate: 4.5%
We obtain:
- Monthly payment ≈ €1,710
- Total interest ≈ €140,400
- Total repaid ≈ €410,400
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:
- Monthly payment: higher rates mean higher monthly payments for the same principal and term.
- Interest share: a larger share of each payment goes to interest at the beginning of the loan, and this effect is stronger at higher rates.
- Borrowing capacity: for a given income, a higher rate reduces the maximum principal you can borrow.
- Break‑even horizon between buying and renting: the number of years after which owning becomes more advantageous can shift significantly when rates change.
Take a household that can allocate €1,500/month to housing costs (excluding charges):
- At 2.5% over 20 years, they can borrow roughly €283,000.
- At 3.6%, this falls to around €255,000.
- At 4.5%, it drops to about €236,000.
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.
- On €270,000 at 3.6% with 0.30% insurance, total insurance cost can exceed €15,000 over 20 years.
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
- Notary fees: typically 7–8% of the price for existing properties, 2–3% for new builds (depending on country and legal system).
- Agency fees: often in the 3–5% range.
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:
- Purchase price: €300,000 (existing property)
- Current rent: €1,200/month (excluding service charges)
- Down payment: €40,000
- Loan term: 20 years
- Property tax: €1,200/year (3% annual increase)
- Annual inflation: 2%
- Investment rate if renting: 4%/year (diversified ETF portfolio, for example)
Case 1: mortgage rates 2026 at 2.5%
With taux_pret = 2.5%:
- Effective loan after fees/down payment: assume €260,000
- Monthly payment ≈ €1,260
- Total interest ≈ €68,000
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%:
- Monthly payment ≈ €1,380
- Total interest ≈ €95,000
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%:
- Monthly payment ≈ €1,500
- Total interest ≈ €120,000
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:
- run an initial simulation with taux_pret = 3.6% (approximate current average),
- then run it again with 2.5% and 4.5%,
- compare after how many years buying becomes more advantageous than renting in each scenario.
At the same time, adjust:
- the investment rate for your savings (3, 4, 5%),
- the annual rent increase (linked to local rent indices, similar to IRL),
- annual inflation,
- the annual property tax increase.
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:
- test several taux_pret assumptions in the simulator,
- keep a safety margin in your budget (avoid stretching your debt‑to‑income ratio),
- avoid basing your entire strategy on the hope that rates will fall soon.
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 full cost of owning (interest, insurance, closing costs, property tax, maintenance, potential renovation),
- the potential return on financial investments if you remain a tenant.
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.
