The two rules
France has two rules. Both must be met.
Every French bank is bound by the HCSF regulation since 2022. The 35% cap is the hard one — but without enough savings, the notary fees alone can block you.
35%
Maximum debt-to-income
Total monthly debt service — mortgage repayment plus mandatory borrower insurance — cannot exceed 35% of net household income. This is a hard cap, not a guideline.
debt <= income x 0.35
10%
Expected down payment
Banks expect at least 10% of the purchase price as apport personnel to cover frais de notaire (~8% for existing properties) and guarantee fees. Not legally required, but practically mandatory.
apport >= 0.10 x price
Have a place in mind?
Drop in a price and see where it fails.
Each test is independent: you need to clear both. The 35% income rule limits your monthly payment; the down payment rule ensures you have cash for notary fees and bank guarantees.

The lever you can actually pull
Two ceilings. Whichever is lower wins.
With your savings fixed, the price you can afford scales linearly with income — until the down payment rule starts to bind. Above the kink, more salary will not buy you a bigger place; more savings will.

Your monthly budget
What you would actually pay each month.
France uses the actual rate — no stress test. Your monthly payment at 3.5% over 25 years is what you qualify on and what you pay. The insurance adds about 0.3% on top.

The stress test charges you 1.0× what you will actually pay. That spread is what you have, in theory, to absorb a rate cycle, or invest, if you would rather.
Where this lands you
Median 3-room apartment, by city.
Your purchase-price ceiling (drawn in cyan) cuts across the price of a typical 3-room apartment (~65m2) in France's largest cities. Cities above the line are out of reach without more income or more savings.

Before you sign
This is probably the largest financial commitment of your life.
A home purchase is not just the price tag. There are significant costs on top that are not included in the affordability test above.
~8%
Frais de notaire (ancien)
For existing properties, notary fees run 7-8% of the purchase price. This covers registration taxes (droits de mutation), notary fees, and various administrative costs. Paid in cash at signing.
1-3%
Taxe fonciere + charges
Annual property tax (taxe fonciere) varies by commune but averages 1-2% of a reference value. Co-ownership charges (charges de copropriete) add another 1-3% for apartments.
?
Renting might still win
In Paris and other expensive cities, the rent-vs-buy math often favors renting and investing the difference, especially for stays under 8-10 years. Ownership locks your capital and has high transaction costs.
None of this means you should not buy. It means you should go in with open eyes. The affordability test tells you what you can do. Whether you should depends on how long you plan to stay, your alternative investments, and the local market dynamics.
