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:

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:

Example with a €300,000 budget:

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:

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:

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:

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

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

By contrast, negotiating the purchase price has a direct impact on:

Example: a €10,000 discount on price

Take an existing property advertised at €300,000 that you negotiate down to €290,000.

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:

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:

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:

For a main home, notary fees produce no direct income. In a buy or rent simulation, you should compare:

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

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:

How this indirectly helps you lower montant_fn

By anticipating all these costs, you can:

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:

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.
