Notary fees on land: the specific calculation you must know

Why notary fees on land follow a specific calculation

Notary fees on land are often summarized as “about 7–8%”, but for a serious buy or rent analysis this shortcut is not enough. The calculation is specific, depends on the type of land (building plot, agricultural, serviced lot), and directly affects the parameter montant_fn (total notary fees) in our simulator. Underestimating this line by just 2 percentage points on a 150,000 € land purchase already creates a 3,000 € error in your scenario.

In France in 2024, notary fees on bare land bought in the “old” market typically stand around 7–8% of the price. For land sold by a developer with VAT, the structure of the fees changes and the effective rate is often closer to 2–3%. The difference can reach several thousand euros and significantly shift the balance in a buy or rent comparison.

Our buy-or-rent.net engine models this item via the montant_fn parameter, which you must fill with the total notary fees on the land. Understanding how to estimate it is key for a realistic simulation.

The components of notary fees on land

Notary fees on land are not a simple commission. They combine four main blocks:

• Transfer taxes and duties: registration tax, land registry tax, and various public levies (usually the largest portion, around 5–6% of the price on old land).
• Notary’s fees (emoluments): regulated remuneration, proportional to the price, often around 0.8–1%.
• Disbursements: amounts advanced by the notary (land registry extracts, planning documents, surveys…), usually a few hundred euros.
• VAT: applied to the notary’s emoluments and some services.

From an investment standpoint, all of these are sunk costs: they do not increase the market value of the land. In a buy or rent comparison, they are an upfront cost that must be weighed against what you could earn by renting and investing your savings instead. That is exactly the role of the montant_fn parameter in the simulator.

Old land vs new land: impact on montant_fn

For the simulator, the nature of the land indirectly drives the level of montant_fn you enter:

• Old land (no VAT on the price): global notary fees usually fall around 7–8% of the purchase price.
• Building land sold with VAT (developer, lot developer): transfer duties are reduced, so total notary fees are often closer to 2–3% of the gross price (price before VAT + VAT).

Illustrative 2024 example:

• Old land 100,000 €: montant_fn ≈ 7,500 € (7.5%).
• New building land 100,000 € + 20,000 € VAT: montant_fn ≈ 3,000 € (≈2.5% of 120,000 €).

For the same 100,000 € base, the gap in notary fees on land can exceed 4,000 €. Over a 20–25 year horizon in a buy or rent scenario, this difference changes the break-even point between buying and renting.

Numerical example: buying a 150,000 € building plot

Assume you are considering a 150,000 € building plot (old land, no VAT on the price) to build a house. You hesitate between buying this land and staying a tenant while investing your savings at 4% per year. Here is how to incorporate notary fees on land into the montant_fn parameter.

Step 1: estimate notary fees on land

Realistic assumptions in 2024:

• Land price: 150,000 €.
• Old land, not subject to VAT on the sale price.
• Global notary fee rate: 7.5% of the price.

Calculation:

• montant_fn = 150,000 € × 7.5% = 11,250 €.

In the buy-or-rent.net simulator, you would therefore enter montant_fn = 11,250 €. This amount is added to the purchase cost of the land but will never be recovered, even if the land doubles in value.

Step 2: how this affects your buy or rent decision

Suppose you finance the land and the future house with a 25‑year mortgage at a loan rate of 3.6%, with borrower insurance at 0.30%. The 11,250 € notary fees on land:

• increase the initial capital you need to pay or finance,
• generate extra interest over 25 years if they are financed,
• represent cash that could have been invested instead.

In the alternative “rent + invest” scenario, you do not pay these 11,250 € of notary fees on land. If you invest them at a placement rate of 4% net per year instead, the future value after 25 years is:

Future value ≈ 11,250 € × (1.04^25) ≈ 11,250 € × 2.666 ≈ 29,243 €.

So the 11,250 € of montant_fn actually carry an opportunity cost close to 30,000 € in the “rent + invest” strategy. The simulator makes this trade‑off visible, instead of hiding it in a vague “buy is always better” statement.

Land + house: why you must separate the costs

In many real‑life projects, you do not buy “just” land; you buy land plus a new house. Legally and financially, these are two different components:

• The land is subject to notary fees (7–8% for old land, 2–3% for VAT‑land).
• The house (under a building contract) is generally subject to VAT, not to classic notary transfer duties.

For the simulator, you should therefore:

• identify the land price separately,
• calculate notary fees only on that land price,
• enter this amount in the montant_fn parameter.

Example:

• Land (old): 80,000 €.
• House (new build, VAT‑included): 220,000 €.
• Assumed notary fee rate on land: 7.5%.

Calculation:

• montant_fn = 80,000 € × 7.5% = 6,000 €.
• Total project cost excluding other fees: 80,000 + 220,000 + 6,000 = 306,000 €.

In the buy or rent logic, the simulator compares this purchase path with the cost of renting (rent plus annual rent increase indexed to inflation) and the performance of your savings if invested instead.

Beyond montant_fn: property tax, works and inflation

Notary fees on land are only one piece of the ownership puzzle. To properly decide whether to buy or rent, you need to combine montant_fn with several other simulator parameters:

• Property tax: for a house on its own land, annual property tax can range from roughly 450 € to more than 5,000 € depending on the municipality.
• Property tax increase: property tax is reassessed almost every year; the simulator models this via an annual revaluation rate.
• Renovation cost (montant travaux): servicing the land (utilities, access road), soil studies, drainage, energy performance upgrades if you later add buildings.
• Annual inflation: inflation erodes the real value of a fixed‑rate mortgage but also impacts rents and construction costs.

The interest rate environment also matters. With mortgage rates around 3.6% in 2024 and savings or ETF portfolios that can aim for 3–5% per year over the long term, the opportunity cost of immobilizing capital in notary fees on land is real. The simulator allows you to set a realistic investment rate and see how much wealth you could potentially accumulate by renting.

Special case: buying agricultural or leisure land

When buying agricultural or purely recreational land, the financial logic changes:

• Notary fees on land are still mostly transfer taxes plus notary emoluments, often around 7–8% for old land.
• However, the land may generate no rent savings (you would not have rented an equivalent plot otherwise).

In this case, the only quantifiable return can be:

• future capital gains if the land appreciates,
• possible rental income (e.g. leasing the land to a farmer),
• and personal utility (which is hard to quantify).

For a pure financial comparison, the montant_fn parameter becomes even more critical. If you pay 8,000 € of notary fees on a 100,000 € plot that does not save you any rent, you should compare this to investing 108,000 € at, say, 4% per year. Over 20–25 years, the gap can be very large. The buy-or-rent.net simulator lets you build such a scenario and see the opportunity cost curve.

How to estimate montant_fn realistically

To feed the simulator with reliable data, you need a robust estimate of the montant_fn parameter. Here are three practical methods:

• Quick rule of thumb: 7.5% of the land price for old land, 2.5–3% for VAT‑land sold by a professional.
• Intermediate method: use a dedicated French notary‑fee calculator for land purchases, then copy the result into montant_fn on buy-or-rent.net.
• Precise method: ask the notary for a detailed fee estimate based on the preliminary sale agreement.

When in doubt, it is safer to slightly overestimate notary fees on land. Underestimating by 1,000–2,000 € may look minor now, but once you factor in a 3–5% annual investment rate over 20+ years, the opportunity cost of that error grows noticeably.

Interaction with loan rate and prepayment penalties

Another subtle effect of notary fees on land is their interaction with your mortgage structure:

• If you finance montant_fn with the loan, you pay interest and insurance on that amount for the full term.
• If you pay it cash, you reduce your financial cushion and your capacity to invest at a positive return.

With current loan rates around 3.6% and borrower insurance typically between 0.25% and 0.45%, financing 10,000 € of notary fees on land over 25 years can lead to several thousand euros in additional interest and insurance premiums.

If you later sell the property and repay the loan early, prepayment penalties (capped at 3% of the remaining principal or 6 months of interest) may also apply. Indirectly, part of these penalties is linked to the financed notary fees. The simulator integrates loan amortization and prepayment assumptions so you can see the full lifecycle cost, not just the purchase day snapshot.

Conclusion: montant_fn is a key input in any buy or rent analysis

For land purchases, notary fees are not a detail. The montant_fn parameter in our simulator captures:

• the specific nature of your land (old vs VAT‑land),
• the exact size of your upfront sunk cost,
• the opportunity cost of this cash compared with long‑term investing,
• its indirect impact on interest, insurance, and potential prepayment penalties.

Whether it is better to buy or rent in your case depends on many factors: land price, local market, rent level, loan rate, investment rate, holding period, property tax dynamics, and more. There is no universal answer. This article provides quantitative guidelines on notary fees for land, but it is not personalized financial advice.

To evaluate your own land purchase project, adjust the montant_fn input, test different loan rates, investment rates and holding periods, and compare against realistic rents.
