Why notary fees matter so much in every buy or rent decision
When you compare whether to buy or rent, notary fees are one of the most underestimated costs. In France, they typically represent around 7–8% of the price for existing properties and 2–3% for new builds. On a €250,000 apartment, that means:
- Existing: €250,000 × 8% ≈ €20,000
- New: €250,000 × 3% ≈ €7,500
These amounts are crucial in any buy or rent analysis because they are one‑off sunk costs: once paid, they never come back, unlike the principal you repay on your mortgage. In the acheter-ou-louer.com simulator, they appear as the parameter montant_fn (total notary fees paid at purchase).
The good news: while you can’t avoid notary fees entirely, you can often save several thousand euros legally. Here are 5 data‑driven tips to save on notary fees and refine your buy or rent decision.
Tip 1: Choose new or recent property to mechanically cut fees
The first way to reduce notary fees is simply to buy a type of property where fees are structurally lower.
Existing vs new: the hard numbers
For the same purchase price, the gap is huge:
- Existing property: notary fees ≈ 7–8% of price
- New build: notary fees ≈ 2–3% of price
Example with a €300,000 budget:
- Existing at €300,000:
- Fees ≈ 8% → €24,000
- montant_fn in the simulator: 24,000
- New at €300,000:
- Fees ≈ 3% → €9,000
- montant_fn: 9,000
Immediate difference: €15,000. That’s the equivalent of several years of rent for some households, or capital that could stay invested at an investment rate of 4–5% per year.
Impact in a buy or rent simulation
In the acheter-ou-louer.com simulator, cutting montant_fn from €24,000 to €9,000:
- reduces the amount you need to finance (if you roll fees into the loan), so you pay less interest at the current loan rate (~3.6%);
- keeps more of your cash free to invest at your chosen investment rate (e.g. 4% in diversified ETFs) instead of being sunk into fees;
- improves the long‑term comparison between buying and renting over 10–20 years.
However, new builds are often more expensive per square metre than older stock, which can offset part of the savings. You need to compare the full picture: price, notary fees, property tax, service charges, resale prospects. Use the simulator to test different montant_fn values and see the real impact on your buy or rent outcome.
Tip 2: Separate property and furniture to reduce the taxable base
The largest part of French “notary fees” are actually transfer taxes, calculated only on the value of the building and land, not on movable items like fitted kitchens, wardrobes, or appliances. By separating the value of the furniture, you can reduce the taxable base and thus the fees.
How it works in practice
Imagine you buy an existing apartment advertised at €260,000 “all inclusive”, with:
- bare property value: €250,000
- furniture and equipment (kitchen, wardrobes, appliances…): €10,000
If you don’t separate them, notary fees are calculated on €260,000. If you do, the taxable base drops to €250,000.
With an 8% rate on existing property:
- Without separation: €260,000 × 8% = €20,800
- With separation: €250,000 × 8% = €20,000
You just saved €800 on notary fees legally. In the simulator, that’s simply lowering montant_fn from 20,800 to 20,000.
Rules you must follow to stay compliant
- The furniture amount must be realistic and documented (invoices, quotes, written estimate).
- In typical apartments, furniture is often in the €3,000–10,000 range, rarely more than 5% of the total price.
- The notary must validate the split and include it in the deed. Artificially inflating furniture value can trigger a tax audit.
In a buy or rent framework, these savings don’t change everything, but they lower your entry cost. Every euro of montant_fn you avoid is a euro that can either stay in cash or be invested at your preferred investment rate instead of being lost in transaction costs.
Tip 3: Negotiate the price, not the notary’s fee
Many buyers assume they can significantly save on notary fees by bargaining with the notary. In reality, most of what we call “notary fees” are taxes paid to the State and local authorities, not the notary’s remuneration.
What is – and isn’t – negotiable
- Transfer taxes (around 5.8% in existing property) are not negotiable.
- Administrative disbursements are heavily regulated.
- Only a small fraction of the notary’s own fee can sometimes be discounted, usually a few hundred euros at best.
By contrast, negotiating the purchase price has a direct impact on:
- the amount of transfer tax you pay;
- the notary’s fee (since it’s partly proportional to price);
- the principal borrowed, and thus interest at the loan rate (~3.6%);
- associated costs like buyer‑paid agency fees or borrower insurance (typically 0.25–0.45% of the loan per year).
Example: a €10,000 discount on price
Take an existing property advertised at €300,000 that you negotiate down to €290,000.
- Notary fees at 8%:
- Before: €300,000 × 8% = €24,000
- After: €290,000 × 8% = €23,200
You save €800 on notary fees plus €10,000 on the price. In the acheter-ou-louer.com simulator, both the property price and montant_fn go down. Over 20 years at 3.6%, that lower principal also means several thousand euros less in interest.
If you chose to rent instead, that €10,800 could remain invested at your chosen investment rate (say 4%). A rigorous buy or rent comparison must therefore factor in:
- the negotiated purchase price;
- the updated montant_fn;
- the potential return of that capital if you don’t lock it into a purchase.
Tip 4: Time your purchase and choose the right project type
Reducing notary fees isn’t only about formulas. It’s also about timing and strategy: what you buy, and when.
Benefit from lower prices to shrink montant_fn
Because notary fees are proportional to price, buying during a period of price correction automatically lowers montant_fn. For example:
- Same property at €320,000 in 2022 → fees ≈ €25,600 (8%)
- Negotiated at €280,000 in 2026 → fees ≈ €22,400
You save €3,200 on notary fees alone, plus €40,000 on price. In a market where mortgage rates hover around 3.6% and annual inflation is high, the buy or rent balance is subtle: lower prices may offset higher rates, but the cash you invest in property is still exposed to inflation risk and opportunity cost.
Primary residence vs rental investment
For a rental investment, notary fees are an entry cost that you can aim to recover through:
- rental income (subject to annual rent increases linked to the IRL index);
- potential long‑term capital appreciation;
- possible tax advantages (e.g. furnished rental regimes, deficit from renovation works, etc.).
For a main home, notary fees produce no direct income. In a buy or rent simulation, you should compare:
- the total cost of buying (interest, montant_fn, property tax that may rise each year, insurance, renovation costs to improve your energy rating);
- with the cost of renting (rent plus IRL‑indexed increases), while investing the cash you don’t spend on buying at your chosen investment rate.
Depending on your holding period (5, 10, 20 years), reducing montant_fn can tilt the outcome, but it never replaces a full analysis of all parameters.
Tip 5: Anticipate all related costs so fees don’t become the least of your worries
Many buyers focus on “how to reduce notary fees” but overlook that the real cost of buying vs renting lies elsewhere. If you ignore these items, an apparently attractive purchase can end up far more expensive than staying a tenant.
Key costs to integrate in your model
- Property tax: from about €450 up to €5,000+ per year depending on the city, with annual reassessment that can be steep.
- Borrower insurance: typically 0.25–0.45% of the loan per year.
- Agency fees: usually 3–5% of the price, sometimes paid by the buyer.
- Renovation cost (montant travaux): to bring the property up to standard and improve DPE/energy performance.
- Prepayment penalties: up to 3% of remaining principal or 6 months’ interest if you repay early.
On a €300,000 existing property with €20,000 notary fees, €10,000 of works and €8,000 agency fees, your real entry ticket is already around €338,000. In a buy or rent simulation, you should compare:
- those €338,000 committed (including the non‑recoverable montant_fn);
- versus staying a renter, paying rent indexed to IRL, but investing the difference at your selected investment rate.
How this indirectly helps you lower montant_fn
By anticipating all these costs, you can:
- negotiate a more realistic price that reflects the true level of renovation needed;
- avoid overpaying for properties with poor energy ratings that require high renovation costs later;
- select locations where property tax is sustainable over time.
Even if the percentage of notary fees stays the same, the absolute montant_fn in euros shrinks because you’re targeting more reasonably priced assets. It’s an indirect but very effective way to save on notary fees and improve your overall buy or rent economics.
Using a buy or rent simulator to measure real‑world impact
The 5 tips above can reduce notary fees, but whether they truly benefit you depends on your own situation: rent level, savings capacity, investment horizon, expected market trends, and how much return you can earn on your capital.
That’s why there is no universal rule like “always buy” or “always rent”. Instead, a tool such as acheter-ou-louer.com lets you:
- enter a precise montant_fn (e.g. €24,000, then €20,000 if you carve out furniture);
- test different loan rates (3.6%, 4%, etc.) and investment rates (2%, 4%, 6%);
- include property tax and its yearly increase;
- add realistic renovation costs, especially if the DPE is poor;
- simulate annual rent increases if you keep renting.
By comparing several scenarios (existing vs new, negotiated vs non‑negotiated price, buying now vs later), you can see how each euro of montant_fn saved shifts the balance in your personal buy or rent equation.
Conclusion: notary fees are a lever, not the whole story
It is absolutely possible to reduce notary fees: buying new, separating furniture, negotiating price, timing your purchase, and anticipating all related costs can significantly lower montant_fn. But they are only one piece of the puzzle. Mortgage conditions, inflation, property tax, renovation needs, and the return on your investments all play a major role in the buy or rent decision.
Whether it’s better to buy or rent will always depend on your individual situation, time horizon, and risk tolerance. This article is for educational purposes only and does not constitute personalised financial advice.
