PTZ 2026: is a deposit required? Complete guide for first-time buyers
Published on July 06, 2026 · PTZ & first-time buyers
Do you dream of buying your first main residence but lack savings? You are asking the crucial question: is a deposit really mandatory to access the Prêt à Taux Zéro (PTZ) in 2026?
The short answer: no, a deposit is not mandatory, but it is more nuanced. This article explains the real conditions of the PTZ, how the financing works in 100 %, and the pitfalls to avoid.
PTZ without a deposit: theoretically possible
What is the PTZ?
The Prêt à Taux Zéro is a state mechanism aimed at first-time buyers (those buying their first main residence) to increase their financing capacity without interest cost.
Key points:
- Nominal rate: 0 %
- Duration varies according to your area and income
- Purchase price ceilings set by geographic area
- Reserved for new or existing property undergoing renovation
A deposit is not a legal condition
Contrary to popular belief, no personal deposit is legally required to apply for a PTZ. Theoretically, you can finance your property entirely through:
- A PTZ (up to 50 % of the purchase price, depending on the area)
- A conventional mortgage (market rate)
- Other aid (Action Logement, family loans, etc.)
However, in practice, banks almost always require a minimum deposit.
Why banks want a deposit, even with a PTZ
The "PTZ without a deposit" paradox
Although legally possible, borrowing 100 % without a deposit carries risks for the lender:
- Default risk: you have no personal funds at stake, so less "skin in the game"
- Over-indebtedness: your debt-to-income ratio (loans / income) rises quickly
- Need for mortgage security: the bank requires a mortgage over the property
- Hidden costs: borrower insurance, arrangement fees, and potentially a guarantee (Crédit Logement, Garantme, etc.)
The reality in 2026: even with PTZ, a deposit of 5 % to 10 % of the purchase price has become highly expected by lending institutions. Some may accept 0 %, but this is rare and more costly.
Debt-to-income ratio: the real limit
Your debt ratio (total loans / net income) should not exceed 35 % (the 2026 standard). With PTZ alone, this balance is fragile.
Concrete example:
- Purchase price: 250 000 €
- PTZ zone B1: ~90 000 € (36 %)
- Remaining mortgage: ~160 000 €
- Notary fees (new-build): ~5 000 €
- Total financing: 255 000 €
- Without a deposit: you must borrow 255 000 €, which may break your debt ratio depending on your income.
With a deposit of 12 500 € (5 %), you borrow 242 500 €, which makes your file breathe.
The real alternatives to the PTZ when you have no deposit
1. Action Logement (formerly -1 % employers' contribution)
If your employer is a member of Action Logement, you gain access to:
- A savings-based housing loan at a reduced rate (subject to conditions)
- A home ownership loan of up to 25 000 € at zero rate
- Additional aid (prima)

2. MaPrimeAdapt' or other local aid
Depending on your region:
- Regional aid for first-time buyers
- Local authority grants (communes, departments)
- Notary fee exemptions (rare but possible)
3. Structured family loans
To bridge the gap without a bank deposit:
- Written family loan (formalised before a notary)
- Temporary gift from a parent or grandparent
- A family loan improves your credibility with the bank (= effective deposit)
4. New-build property with reduced VAT
Buying new-build offers advantages regarding the deposit:
- Reduced notary fees (2–3 % vs 7–8 %)
- Possibility of reduced VAT (5,5 %) in certain areas
- Lower initial outlay, so easier to finance without a deposit
Strategy: how to optimise PTZ + mortgage without a deposit (or with a minimal one)
Step 1: Choose your property carefully
New-build is required to reduce initial costs.
- Compare two PTZ/area scenarios to maximise the interest-free loan ceiling
- Favour areas where the PTZ % is higher (zone A bis or A)
Step 2: Optimise your financing structure
| Need | Amount | Source |
|---|---|---|
| Purchase | 250 000 € | PTZ (90 k) + conventional mortgage (160 k) |
| Notary fees | ~5 000 € | Action Logement or small savings |
| Borrower insurance | ~3 000 € | Included in the loan |
| Unforeseen costs | ~2 000 € | Small deposit (2 % = 5 k) |
Realistic minimum deposit: 5–8 k € (2–3 % of the price).
Step 3: Demonstrate your stability
Even without a deposit:
- CDI or stable profession (essential)
- Clean banking history (no defaults)
- Verifiable income (Kbis, tax notices, payslips)
- Complete and responsive file (builds confidence)
Step 4: Negotiate with banks
Two strategies:
Option A: Show a small deposit (5–10 %)
- Reduced mortgage
- Better debt ratio
- More competitive rate
Option B: Zero deposit + guarantee (Crédit Logement)
- Guarantee cost approx. 1,5 % of the amount borrowed
- Accepted by more banks
- Requires a thorough file review

Pitfalls to avoid
❌ Pitfall 1: Borrowing too quickly without comparing
Do not sign with the first bank. Compare 3–4 offers:
- Standard loan rate
- Arrangement fees
- Borrower insurance cost
- Repayment terms PTZ (deferral, stages)
❌ Pitfall 2: Overlooking hidden costs
Without a visible deposit, you bear:
- Credit insurance (0,3–0,6 % per year)
- Mortgage guarantee fees
- Arrangement fees (200–500 €)
- New-build notary fees (always payable)
Total real costs: 5–8 k € on a property at 250 k €.
❌ Pitfall 3: Exceeding your debt ratio
Even with PTZ, if your ratio rises above 35 %, the bank refuses. Calculate precisely:
(PTZ + Crédit classique + Autres crédits) / Revenus nets mensuels < 35 %
❌ Pitfall 4: Forgetting that PTZ = real charges
The PTZ is interest-free, but not cost-free:
- Compulsory borrower insurance
- Notary fees (even on new builds)
- Mortgage (registration fees)
PTZ 2026: the important changes
2026 context:
- Tighter access conditions (stricter debt ratio)
- PTZ ceilings maintained but zones reassessed
- Relative rise in mortgage rates → deposit even more useful
- Action Logement active, but criteria more selective

Conclusion: zero deposit is possible but difficult
The simple truth:
✅ Legally: you can obtain PTZ without a deposit
❌ In practice: almost everyone is asked for a minimum deposit (5–10 %)
💡 Strategically: a small deposit (2–5 k €) is better than a rejected file
Your action:
- Save at least 2–5 k € as a serious first-time buyer
- Target new-build property (reduced fees, VAT possible)
- Explore Action Logement (often overlooked)
- Consult a JL HOME adviser to optimise PTZ + loan according to your exact profile
An expert can:
- Check your actual PTZ eligibility (zone, 2026 ceilings)
- Simulate your financing without a deposit
- Negotiate with partner banks
- Identify hidden aid (Action Logement, local schemes)
Frequently asked questions
Q: PTZ and zero deposit: a real option in 2026?
A: Yes, but rare. Banks prefer 5–10 % as a deposit. It is less an obstacle than a difficulty to overcome with a sound file and an optimised structure.
Q: Does Action Logement replace the deposit?
A: Partly. Its accession loan (up to 25 k €) can cover fees and part of the price, freeing your cash for the expected bank deposit.
Q: What minimum deposit avoids rejection?
A: 5 % of the purchase price (= 12 500 € on 250 k €). Below this, the file is very tight; above it, normal comfort.
Q: PTZ + standard loan + Action Logement: does it work?
A: Yes, it is often the best structure. It allows a minimal deposit and maximises your borrowing capacity.
Q: Are notary fees and insurance included in the PTZ?
A: No. The PTZ finances the purchase price. Fees and insurance must be paid or built into a standard loan.
