Buying from a private seller: does skipping agency fees really pay off?

Buying a home from a private seller, without an intermediary, is increasingly popular among buyers who want to save several thousand euros in agency fees. But are these savings always meaningful when you look at the bigger buy or rent question? And what concrete risks do you take when you cut out the middleman?

This guide focuses on one key simulator parameter: montant_fa (amount of agency fees). We’ll show, with numbers, how removing agency fees affects:

The goal is not to tell you whether you should buy or rent, nor to give personal financial advice, but to provide data so you can decide. Simulate your situation on buy-or-rent.net to adapt these examples to your own numbers.

1. What do agency fees really represent?

In many European markets, real estate agency fees typically range around 3–5% of the sale price, sometimes more on smaller properties. In the simulator, this cost is captured by the parameter montant_fa.

1.1 A simple numerical example

Let’s assume an apartment advertised as follows:

With a standard agency sale, you pay €260,000 (before closing costs). If you buy from a private seller, without intermediary, and the seller agrees to sell at the same net price (€250,000), you immediately save €10,000. That amount corresponds to montant_fa = 10,000 in the simulator.

But the impact goes beyond just €10,000: it also affects closing costs, loan size, interest paid, and ultimately your buy or rent comparison.

2. How agency fees change your total cost of buying

2.1 Impact on closing costs

Notary or closing costs are often a percentage of the purchase price: roughly 7–8% for older properties and 2–3% for new builds in France, with similar logic in other markets. Depending on how the contract is structured, including or excluding agency fees in the taxable base can slightly change the amount of tax and fees you pay.

Let’s keep our example:

Additional saving: about €800 on closing costs, on top of the €10,000 agency fee you don’t pay.

2.2 Impact on your mortgage and interest payments

Assume:

Scenario A – With agency

Scenario B – Private seller, no intermediary

Difference: €10,800 less principal to borrow (agency fees + lower closing costs).

At 3.6% over 25 years, monthly payments (excluding insurance) are roughly:

That’s about €55 less per month. Over 25 years, this translates into more than €16,000 saved in principal and interest. The montant_fa parameter therefore has a long-term impact on your finances, not just a one-off saving.

3. Financial benefits of buying from a private seller

3.1 Direct saving on agency fees

The most obvious benefit when you buy from a private seller is avoiding agency fees. For properties between €200,000 and €400,000, the typical saving ranges from €6,000 to €20,000, depending on the commission rate.

In the buy or rent simulator, by setting montant_fa = 0, you model a transaction without an agent. You can then compare this to a purchase with an agent (for example montant_fa = 12,000) and see the effect on:

3.2 More room for negotiation?

Without an agent, some sellers are willing to lower their price because they don’t have to pay commission. For example, a seller who wanted €250,000 net and added €10,000 of fees might agree to sell directly for €250,000, or even €245,000 if you negotiate well.

An extra €5,000 discount on top of skipping agency fees further reduces your loan amount and interest paid. In a buy or rent comparison, every euro saved at purchase improves the long-term performance of ownership versus renting.

4. Specific risks when buying from a private seller

Skipping agency fees is attractive, but removing the intermediary shifts more responsibility and risk onto you as the buyer.

4.1 Risk of mispricing the property

Agents (at least good ones) bring market expertise: recent comparable sales, knowledge of the neighbourhood, of demand trends, and of typical discounts. In a private sale, the seller may overprice or underprice the property.

Example:

You might feel you’re getting a deal paying “only” €270,000 with no agency fees, whereas with an agent the property might have been listed at €260,000 including €10,000 commission. You’re effectively overpaying by €10,000, cancelling out the fee saving in your buy or rent equation.

4.2 Legal and administrative risk

Agents also help secure the transaction: checking documents, coordinating with the notary, chasing missing information. In a private sale, you must personally ensure that:

Missing or misunderstood information can be costly. For example, finding out after purchase that a facade renovation of €25,000 is due and at your expense can wipe out the benefit of saving €10,000 in agency fees.

4.3 Underestimated renovation and upgrade costs

A diligent agent usually flags visible issues. In a direct deal, the seller may downplay needed work. Yet renovation cost (another key simulator parameter) can be a game changer in your buy or rent decision.

If you save €12,000 on agency fees but discover €20,000 of unexpected work (roof, wiring, insulation to improve the energy rating), the net financial outcome is negative. Your real budget is price + closing costs + renovation, and that total must be compared to the cost of renting a similar property.

5. Buying from a private seller vs renting: a global comparison

Choosing a private purchase isn’t just about cutting agency fees. You need to integrate it into the overall buy or rent strategy over 10, 15 or 20 years.

5.1 Comparing two buying scenarios

Imagine a household considering:

Shared assumptions:

In the simulator, the difference in montant_fa will:

Next, you compare both buying scenarios with renting a similar property:

The buy or rent simulator shows after how many years each buying option overtakes renting in terms of net wealth.

5.2 When does skipping agency fees really matter?

The higher montant_fa is relative to the property price, the more attractive a private purchase can be. On a small €120,000 apartment with €8,000 agency fees (~6.7%), the saving is proportionally large and may represent several years of rent.

On the other hand, on a very expensive property where you negotiate a 2% fee, the relative gain is smaller, and the risk of overpaying in a private deal can easily erase the advantage.

6. Best practices when buying from a private seller

6.1 Do your own market homework

Before making an offer, you should:

This helps you avoid “giving back” your agency fee saving by paying too much.

6.2 Use a notary and, if needed, an independent valuer

Even in a private sale, never skip the notary or legal professional. You can:

These costs (often a few hundred euros) are far below typical agency fees and significantly reduce legal and financial risks.

6.3 Feed all costs into your simulator

In your buy or rent reasoning, don’t just look at the advertised price:

On the renting side, account for rent indexed to inflation or a rental index, tenant insurance, and most importantly the capital you can invest at your assumed investment rate.

7. Conclusion: private seller or agent, buy or rent still depends on you

Buying from a private seller, without intermediary, often reduces montant_fa and therefore the overall cost of buying. However, risks (mispricing, legal issues, underestimated works) can quickly erode or even exceed the saving if the deal is not carefully prepared.

There is no universal rule: whether you should buy or rent depends entirely on your situation (how long you’ll stay, local rent levels, mortgage rate, taxes, life plans). This article is not personal financial advice, but a data-driven framework to help you think.

To see whether, in your specific case, buying from a private seller really improves your buy or rent outcome, adjust the montant_fa parameter and all other key settings (loan rate, property tax, investment return, inflation, renovation, etc.). Simulate your situation on buy-or-rent.net and compare, in a few clicks, different buying scenarios (with or without agent) against renting the same type of home.
