The interest-free loan (PTZ) remains in 2026 one of the rare pieces of public support that genuinely changes the equation for a first-time buyer in Paris. In a city where the average price per square metre exceeds 10,000 euros and where the required personal deposit runs to tens of thousands of euros, an interest-free loan of 100,000 to 180,000 euros is not a gimmick: it is the difference between a feasible project and a deferred dream.
Yet the PTZ remains underused. The eligibility conditions are perceived as complex, the income thresholds seem exclusionary, and many Parisian first-time buyers assume, wrongly, that they earn too much to qualify. Others do not know that the PTZ has been significantly broadened in recent years, with more flexible conditions and more generous amounts.
At Home Select, our property hunters regularly support first-time buyers through their first purchase in Paris. The PTZ is one of the financing levers we integrate from the outset of the discussion, not as a last-minute bonus, but as a pillar of the financing plan that determines the search budget and therefore the type of property accessible.
The PTZ in 2026: what has changed
The PTZ has undergone several major changes since its creation. The recent trend is toward broadening the scheme, with a stated political intention to facilitate home ownership in high-demand zones like Paris.
The most significant changes for Parisian buyers concern the broadening of eligibility for existing property (subject to works and energy performance conditions), the revision of income thresholds to better reflect the cost of living in zone A bis, and the increase in the financeable quota for low and middle-income households.
Paris is classified as zone A bis, the most high-demand zone in the country, with the most favourable operation ceilings and conditions. This is a structural advantage for Parisian first-time buyers: the maximum PTZ amount is the highest in France.
Important: the precise PTZ conditions (income thresholds, quotas, repayment durations) are set by decree and may change from one year to the next. The information in this article reflects the general framework of the scheme in 2026. Before assembling your application, check the current scales on service-public.fr or with the ANIL (Agence Nationale pour l’Information sur le Logement). Your bank or broker can confirm the exact conditions applicable to your situation.
Eligibility conditions: who can qualify?
The PTZ is subject to three main conditions: a first-time buyer condition, an income condition, and a condition related to the property purchased.
First-time buyer status. You must not have owned your primary residence during the two years preceding the loan offer. If you own a second home or a buy-to-let investment, you remain eligible: it is the primary residence that counts. The exceptions to the first-time buyer condition are limited: holders of an invalidity card or the mobilite inclusion card, victims of a natural or technological disaster that rendered the home uninhabitable.
A point many overlook: if you are in a couple and one partner already owns or has owned their primary residence within the past two years, the PTZ is excluded for the couple. However, if your partner owns a rental property or a second home, the PTZ remains accessible.
Income thresholds. The fiscal reference income for year N-2 (shown on your tax notice from the year before last) must not exceed a threshold that varies by geographical zone and household size. In Paris (zone A bis), the thresholds are the highest in the country.
As a guide for zone A bis, the approximate thresholds are as follows: approximately 49,000 euros for a single person, approximately 73,000 euros for a couple without children, approximately 88,000 euros for a couple with one child, approximately 105,000 euros for a couple with two children. These thresholds should be verified, as they are revised by decree and the exact amounts in force at the date of your application may differ.
A Parisian couple with two children earning a combined fiscal reference income of 95,000 euros may therefore be eligible for the PTZ. This is not a scheme reserved for very low-income households. It is a tool accessible to a broad section of the Parisian middle class.
Property conditions. The PTZ finances the purchase of a primary residence. The property must be occupied as a primary residence within one year of purchase (or completion of works). Letting is only permitted after a personal occupation period of six years.
In Paris, the PTZ is accessible for new-build purchases (apartment off-plan or construction) and, subject to conditions, for existing property with works. For existing property, works must represent at least 25% of the total operation cost and the property must reach a minimum energy performance level after works. These conditions steer the existing-property PTZ toward properties requiring significant renovation, which happens to correspond to part of the Parisian housing stock (apartments rated E, F or G on the DPE).
The PTZ amount: how much can you borrow?
The PTZ amount calculation combines three parameters: the capped purchase price, the financeable quota, and the household income bracket.
The capped purchase price. The PTZ does not finance the entire purchase price. An operation ceiling is set by zone and household size. In Paris (zone A bis), these ceilings are the highest. For a couple with one child, the ceiling is around 360,000 euros, which in Paris corresponds to a studio or small one-bedroom in the least expensive arrondissements. For a couple with two or more children, the ceiling is higher.
The financeable quota. The PTZ finances a percentage of the capped price, which varies by household income bracket. The lowest-income brackets benefit from a quota of up to 50%, while intermediate brackets sit at around 20 to 40%. The more modest your income (within the thresholds), the more generous the PTZ proportionally.
An indicative example. A couple with one child, fiscal reference income of 60,000 euros, buys an apartment in Paris for 350,000 euros. If the applicable operation ceiling is 360,000 euros, the price used is 350,000 euros. With a quota of 40% (based on income bracket), the PTZ would be 140,000 euros. That is 140,000 euros borrowed at 0% interest: a saving of several tens of thousands of euros in interest over the loan term.
The exact amounts depend on the scales in force. A simulation on the ANIL website or through your broker is essential to know the precise amount you are entitled to.

Repayment: the real advantage of the PTZ
The absence of interest is the obvious advantage of the PTZ. But the repayment mechanism is an equally important advantage, often underestimated.
The PTZ includes a deferred repayment period during which you repay only your main loan, not the PTZ. This deferral ranges from 5 to 15 years depending on your income: the more modest your income, the longer the deferral. During the deferral, your monthly payments are reduced since you are repaying only one loan instead of two.
After the deferral, PTZ repayment is added to the main loan repayment, but over a short period (10 to 15 years) and interest-free. The increase in monthly payments is predictable and can be anticipated in the financing plan.
This mechanism is particularly suited to first-time buyers at the start of their career, whose income is expected to grow in the years following the purchase. The deferral allows them to manage moderate monthly payments in the early years, when their repayment capacity is most constrained.
The total PTZ duration (deferral plus repayment) can reach 20 to 25 years depending on income bracket. This is consistent with a standard mortgage of 20 to 25 years: both loans mature at roughly the same time.
The PTZ in the Paris buying strategy: what changes in practice
The impact of the PTZ on a Parisian purchase project is measured at three levels.
Increased search budget. A PTZ of 140,000 euros at 0% interest is the equivalent of a standard loan of 160,000 to 170,000 euros in terms of total cost over 20 years (principal plus interest). The interest saving allows borrowing more at constant monthly payment, or reducing monthly payments at constant purchase budget. Either way, the PTZ broadens the field of possibilities.
Reduced deposit requirement. The PTZ is treated as personal deposit by some banks, which reduces the savings needed to assemble a solid financing application. A first-time buyer with 40,000 euros in savings and a PTZ of 120,000 euros has an effective deposit of 160,000 euros, a significantly more attractive profile for banks than a deposit of 40,000 euros alone.
Access to better-located properties. In Paris, 50,000 euros of additional budget makes the difference between a studio in the 19th and a studio in the 11th, or between a dark one-bedroom on the first floor and a bright one on the fourth. The PTZ does not transform a modest budget into a luxury one, but it shifts the cursor enough to access significantly better properties.
Our property hunters integrate the PTZ from the outset when defining the brief. A client eligible for the PTZ does not search for the same properties as a non-eligible client with an apparently equivalent budget: their real budget is higher, and the accessible arrondissements and property types differ.
PTZ and existing property with works: the Parisian opportunity
The extension of the PTZ to existing property with works opens an opportunity window in Paris, where the older housing stock is vast and many apartments require energy renovation works.
The principle is as follows: the PTZ finances the purchase of existing property provided that works representing at least 25% of the total operation cost (purchase plus works) are carried out, and the property reaches a satisfactory energy performance level after works.
In concrete terms, for a purchase at 300,000 euros with 100,000 euros of works (total cost 400,000 euros), works represent 25% of the total, meeting the minimum threshold. The works must bring the property to an energy consumption level that meets the scheme’s requirements.
This profile corresponds exactly to the type of purchase our property hunters regularly identify for first-time buyers: a well-located but run-down Parisian period apartment (DPE rated E, F or G), purchased at a 10 to 20% discount relative to the renovated market, and renovated to achieve a good performance level. The existing-property PTZ transforms what was a constraint (the obligation to renovate) into a financial opportunity (interest-free financing).
The typical arrangement: purchase of a two-bedroom of 55 m2 in the 20th arrondissement at 320,000 euros (as-is, DPE F) plus 110,000 euros of full renovation including insulation, windows and modernisation. Total cost: 430,000 euros. Works equal 25.6% of total, meeting PTZ eligibility. Estimated PTZ: 80,000 to 130,000 euros depending on household income. After works, the apartment is worth 420,000 to 450,000 euros in good condition with a DPE of C or D: a significant latent capital gain.
Common first-time buyer mistakes
Fifteen years of supporting first-time buyers in Paris have taught us that certain errors recur systematically.
Not checking PTZ eligibility. Many first-time buyers assume they earn too much. Before ruling out the PTZ, run a simulation. The zone A bis thresholds are higher than most people imagine.
Assembling the mortgage application without mentioning the PTZ. Some banks do not proactively offer the PTZ unless the client requests it. The PTZ is distributed by banks that have signed an agreement with the state: virtually all major French banks. But the initiative falls to the client or their broker.
Underestimating the processing time. Assembling an application with a PTZ is slightly more complex than a standard mortgage (additional documents, eligibility verification). Allow a processing time of six to eight weeks, which means starting the banking process as soon as the preliminary agreement is signed, without delay.
Forgetting that the PTZ is a supplementary loan. The PTZ finances only part of the purchase price. It must be supplemented by a main loan (standard bank mortgage) and ideally by personal savings. The financing plan must be conceived holistically: PTZ plus main loan plus deposit, plus potentially an Action Logement loan or housing savings loan (PEL).
Confusing primary residence and investment. The PTZ finances primary residences exclusively. If your project is a buy-to-let investment, the PTZ is not accessible. If you purchase a primary residence with the PTZ and subsequently wish to let the property, you must have occupied the home for at least six years.

PTZ and property hunter: a logical combination
The first-time buyer eligible for the PTZ is, almost by definition, a buyer who needs good support. Their budget is constrained, their knowledge of the Parisian market is often limited (it is their first purchase), and the financial stakes are proportionally greater: a 20,000 euro mistake on a 350,000 euro budget weighs more heavily than on a one-million-euro budget.
The involvement of a property hunter makes complete sense in this context. Identifying properties to renovate that are eligible for the existing-property PTZ, evaluating the works budget to verify the 25% threshold, negotiating the purchase price to maximise the margin between price paid and value after works, coordinating with the broker to optimise the PTZ-plus-main-loan financing plan: each step requires expertise the first-time buyer does not have.
At Home Select, the average negotiation of 6% on the seller price represents, on a purchase at 350,000 euros, a saving of 21,000 euros. Combined with a PTZ of 120,000 euros, this saving radically changes the project’s financial equation. It is no longer a tight purchase: it is a controlled purchase, with safety margins for the unexpected.
The PTZ is a powerful tool. But like any tool, it delivers the best results in the hands of someone who knows how to use it.
Frequently asked questions
Is the PTZ available for buying existing property in Paris in 2026?
The PTZ has been broadened since 2024. In Paris (zone A bis), it is accessible for new-build collective housing and, under certain energy performance conditions, for existing property with works representing at least 25% of the total operation cost. As the exact conditions evolve each year, check the criteria in force at the time of your project with your bank or on service-public.fr.
What are the income thresholds for the PTZ in Paris?
Paris is classified as zone A bis, the most high-demand zone. Income thresholds depend on household size. For a single person, the threshold is around 49,000 euros of fiscal reference income. For a couple with two children, around 74,000 euros. These thresholds are revised regularly. Check the current scales before assembling your application.
How much can you borrow with the PTZ in Paris?
The PTZ amount depends on the capped purchase price, the financeable quota and the income bracket. In Paris, the operation ceiling for a couple with one child is approximately 360,000 euros, and the quota varies from 20 to 50% depending on income. The PTZ can thus represent 70,000 to 180,000 euros of interest-free financing, a considerable lever for first-time buyers.
Can the PTZ be combined with other aids in Paris?
Yes. The PTZ can be combined with a standard mortgage, an Action Logement loan (employer-assisted), a housing savings loan (PEL/CEL), and any available local aids. Combining these schemes can significantly reduce the total credit cost for a first-time buyer.
Do you need to be a first-time buyer to qualify for the PTZ?
Yes. The PTZ is reserved for people who have not owned their primary residence during the two years preceding the loan offer. Exceptions exist: victims of natural disasters, persons with a disability holding an invalidity card.
