«Buying is always smarter than renting, you’re just throwing money away otherwise.» We must have heard some version of that sentence a hundred times over the years, usually from people who never actually ran the numbers on their own situation. It isn’t wrong exactly. It’s just far less universal than it sounds.
Whether buying beats renting depends almost entirely on how long you plan to stay put and how the numbers work in your specific case, not on a general rule. Below five years, renting usually wins once you account for notaire fees and the cost of selling again. Beyond seven to fifteen years in the same place, buying tends to pull ahead, especially if the property is well negotiated.
The short version:
- Under 5 years in the same home, renting is usually the more rational financial choice once purchase and resale costs are counted.
- Between 7 and 15 years, buying tends to become advantageous, particularly with a well-negotiated price.
- Mortgage rates sat around 3.15% to 3.40% in mid-2026 depending on the loan length, a real factor in the calculation.
- Your job’s mobility and your own temperament matter just as much as the maths, maybe more.
The break-even point nobody mentions at the dinner table
Buying a home comes with costs that renting simply does not: a down payment, notaire fees running 7 to 8.5% of the price, and if you sell again within a few years, agency fees on the way out too. Those upfront costs need time to be absorbed by the equity you build with each mortgage payment.
As a rough rule that keeps coming up across the market analyses we have read this year, staying under five years in the same property usually favours renting once those transaction costs are factored in. Between seven and fifteen years, the balance tends to tip toward buying, and a genuinely well-negotiated purchase price can shift that break-even point earlier still. Nobody can give you an exact number without knowing your specific mortgage rate, your down payment, and the local market, but the principle holds fairly consistently.
What today’s mortgage rates change in the equation
Rates move the whole calculation more than people expect. In mid-2026, average French mortgage rates sat around 3.15% over 15 years, 3.25% over 20 years, and 3.40% over 25 years, with some forecasts pointing toward a slight further rise by year end. A percentage point of difference on a 20-year loan changes your monthly payment enough to shift the buy-versus-rent balance on its own, which is exactly why we always tell people to run their own simulation rather than trust a rule of thumb from a few years ago.
If your work moves you every few years
This is where the original advice we grew up hearing actually holds up well: if your job pushes you to relocate every three to five years, owning your main home can become a genuine headache, selling and buying again each time eats into any equity gained. A rental investment bought in one place while you keep renting wherever your work sends you can make more sense: it builds equity and produces rental income without tying your own housing to a single address.
This is also, in our experience, as much a question of personality as of spreadsheets. Some people genuinely thrive on the freedom of a lease they can walk away from with a month or two’s notice. Others feel unsettled without four walls that are truly theirs. Neither instinct is wrong, but it is worth being honest with yourself about which one describes you before signing anything.
The zero-interest loan trap to know about
France’s prêt à taux zéro (PTZ) is a genuinely useful tool for a first purchase, but it comes with a condition that catches people out: the property must become your main home within a year and generally stay that way for at least six years, with only limited exceptions (job relocation, health reasons, retirement). If you already know your situation is likely to change within that window, whether professionally or personally, factor that constraint in before applying, since it can conflict directly with a mobile lifestyle.
We chose to keep renting for years before buying anything, mostly because Michel’s work kept moving us around. Looking back, it was the right call for that period of our life, even if it wasn’t the «smart» answer everyone kept repeating to us.

Frequently asked questions
Is buying always cheaper than renting in the long run? Only if you stay long enough to absorb the purchase and resale costs, generally beyond seven years, otherwise renting often works out cheaper overall.
What is the PTZ and who can get it? A zero-interest loan for first-time buyers under income conditions, which requires making the property your main home within a year and keeping it that way for around six years.
Does a rising mortgage rate change the answer? Yes, significantly, a higher rate pushes the break-even point further out and can tip a borderline decision back toward renting.
Can I buy a rental investment while renting my own home? Yes, and it is a common strategy for people with mobile careers, it builds equity and rental income without tying your own address down.
This reflects our own experience weighing this decision more than once, not financial advice: a mortgage broker or financial adviser can run the actual numbers for your income, rate and local market far more precisely than we can here.
