A rent that increases every year, a loan whose total cost makes one hesitate: the choice between renting and buying in 2026 is not just a personal preference. The conditions of the real estate market have significantly changed over the past two years, and traditional benchmarks no longer quite apply. Before signing anything, some recent data deserve careful consideration.
Duration of profitability for real estate purchase: the threshold that has changed
Are you wondering how many years it takes for a purchase to become more advantageous than renting? This timeframe varies by city, interest rates, and prices per square meter. In Paris, with rates around 3.2% over 25 years and prices that have stopped rising after a correction, the profitability threshold for buying has dropped from 29 years in 2024 to 21 years in 2025.
In practical terms, a household planning to stay in its home for more than twenty years now has an interest in buying in the capital. This calculation is based on comparing the total cost of the loan (interest, insurance, notary fees, property tax) with the cumulative rents paid over the same period.
For medium-sized cities where prices are lower, this threshold often falls below fifteen years. This criterion is detailed in the Tout Immo real estate guide, which offers a local approach to the calculation. The idea is simple: the longer you stay, the more buying wins out. If you change cities every five years, renting remains almost always less expensive.
Increase in rents in 2026: renting loses its flexibility
One of the classic arguments in favor of renting is mobility. You sign a lease, you can leave with notice, no notary fees or resale to manage. On paper, this is still true.
In reality, the situation has evolved. According to the SeLoger-Meilleurs Agents barometer, rents have increased by an average of 2.6% in France over one year as of July 1, 2026, and by 4.7% in Paris. This increase erodes tenants’ budget margins and reduces the monthly cost gap with loan repayments.
Another notable fact: a Maslow.immo study covering nearly 30,000 leases shows that the average length of stay for tenants has increased from 28.3 months in 2019 to 37.6 months in 2025. This is an increase of 33%. Tenants are staying longer, often out of necessity (rental pressure, difficulty finding better) rather than by choice.
This data challenges the idea that renting equates to flexibility. When the market is tight and rents are rising, moving becomes a financial gamble, not an advantage.
Real estate project and taxation: what really weighs in the balance
Beyond the calculation of monthly payment versus rent, taxation plays a decisive role. An owner-occupier does not pay tax on a potential “notional rent” (the rental value of their own home). This is an invisible but real long-term advantage.
For those considering a rental investment, the LMNP (non-professional furnished rental) regime remains a profitability lever, but the 2025 reform has changed the treatment of depreciation. LMNP depreciations are now reintegrated into the calculation of capital gains upon resale, which reduces the net tax advantage. This is a point to consider in any rental yield calculation.
Concrete criteria to evaluate before deciding
- The expected duration of occupancy of the property: below seven to eight years, renting is generally less expensive once acquisition costs are taken into account
- The monthly effort rate: the loan payment should not exceed 35% of net income, a rule applied by banks since the recommendations of the HCSF
- The capacity for personal contribution: without a down payment, the total cost of the loan increases significantly and extends the profitability threshold
- The expected evolution of income: a purchase is more justified if income is stable or increasing, as the monthly payment remains fixed while rents rise each year
Buy or rent in 2026: three profiles, three different answers
There is no single answer. Let’s take three typical situations to illustrate.
The young professional at the start of their career
Strong professional mobility, limited savings, uncertainty about the medium-term city of residence. Renting remains the rational choice for this profile, provided one does not remain a tenant out of inertia when the situation stabilizes.
The settled couple with regular income
Life project anchored in a city, established savings, predictable income. Buying makes perfect sense here, especially since current rates, although higher than those of 2021, allow for controlled loan costs over 20 or 25 years.
The property investor
For those seeking rental yield, the shortage of rental housing in many urban areas keeps occupancy rates high. The tight rental market works in favor of the investor, but the net profitability depends on the chosen tax regime and the purchase price. A precise calculation, incorporating the LMNP reform, is necessary before proceeding.
The real estate market of 2026 is neither euphoric nor in crisis. Prices are stabilizing, rates remain above 3%, and rents are rising. In this context, the right question is not “should I buy or rent” in general, but “how long will I stay in this property and what monthly financial effort can I absorb without straining my budget.” The answer to these two questions almost always settles the debate.
