Estate agent commission in Madrid 2026: how much you pay to sell a flat and how to save

For many families, selling a flat in Madrid is the biggest financial transaction of their lives. And there is one item that is often looked at too late and too lightly: the estate agent's commission. With an average price of €6,458/m² in the city of Madrid in September 2026, according to idealista, each percentage point of commission can mean several thousand euros.

In this guide we look at how much an estate agency really charges to sell a flat in Madrid, using data from the OCU (Spain's main consumer organisation) and specialist websites; what it means in euros; who pays it and when; what double commission is; which hidden costs come up most often; and what consumer law says. At the end you will find a checklist for reviewing the listing agreement. You will find the complete sales process in our guide “How to sell a flat in Madrid in 2026”.

How much an estate agency charges to sell a flat in Madrid in 2026

There is no official rate. Estate agent commission is freely set in Spain: each agency sets its own and agrees it with the owner in the listing agreement, which in the sector is usually called the hoja de encargo. As RealAdvisor points out in its guide updated in June 2026, there is no percentage set by law and no maximum cap.

The most recent figure with a known methodology comes from the OCU. In January 2026 it published a survey of 60 agencies in Barcelona, Madrid, Seville, Valencia and Zaragoza: sales commissions ranged from 2% to 6% of the price, with an average of 5%. In June 2024, a survey of sellers by the same organisation showed that 63% had sold through an agency and that the average commission paid was 3.6% plus VAT. What the agency asks for at first is not always what the seller ends up paying: commission is negotiable.

Comparison websites give similar ranges. HelpMyCash, in its February 2026 guide, puts traditional estate agencies at between 3% and 7%, with cases of up to 8%. RealAdvisor talks of between 3% and 7% plus VAT, and up to 10% for luxury homes over €500,000.

In practice, several charging models now exist side by side, and it is worth knowing which one you are dealing with before comparing:

• Percentage of the sale price: the classic model. The usual range is 3% to 7% plus VAT, with an average of 5% in the OCU's 2026 survey.
• Fixed fee: offered mainly by online estate agencies, with amounts of about €2,000 to €8,000 depending on the service chosen (RealAdvisor and HelpMyCash, 2026).
• Monthly fee or subscription: some online agencies charge from about €60 a month, according to HelpMyCash, whether or not the sale goes through.
• Agreed reduced commission: in 2024 the OCU negotiated with several agencies a commission of 2.5% plus VAT for its members, and slightly less for some subscribers.

It pays to compare carefully. A low fixed fee may come with services that are paid for separately, and a high percentage may include things another agency charges for separately. What matters is knowing the total cost, including tax, and exactly what it covers.

Estate agent commission and VAT: the 21% that sometimes goes unmentioned

An estate agency's commission is a professional service and carries 21% VAT. The OCU warns that this tax is not always made clear and that commission is usually advertised without it. HelpMyCash adds that traditional agencies tend to charge it on top, while online ones tend to include it in their fee.

The difference is not small. A 5% “plus VAT” is really 6.05% of the sale price. On a €450,000 flat, the gap between reading “5%” and paying 5% plus VAT is €4,725. So when you compare proposals, always ask for the final figure in euros including VAT, and ask for it to appear that way in the contract.

What commission means in euros: examples with Madrid prices

To make the percentages easier to understand, we have calculated the commission for three typical prices in Madrid. For reference, idealista put the average asking price of homes for sale in the city of Madrid at €6,458/m² in September 2026, ranging from €3,365/m² in Villaverde to €10,865/m² in the Barrio de Salamanca. Fotocasa gave €5,455/m² in July for second-hand homes across the Comunidad de Madrid (Madrid region), according to El Español.

At those prices, €300,000 is equivalent to about 46 m² at the city average; €450,000, to about 70 m² in the city or 82 m² at the regional average; and €600,000, to about 93 m² in the city or 110 m² in the region. These are very common prices in the Madrid market.

Source: our own calculation (price × percentage × 1.21 for 21% VAT). Reference prices: idealista (September 2026) and Fotocasa (July 2026).

And this is what the seller keeps by paying 2.5% + VAT instead of each of the other commissions:

Source: our own calculation. Difference in euros, VAT included, between each commission and one of 2.5% + VAT.

Put another way: on a €450,000 flat, going from 5% to 2.5% plus VAT leaves €13,612.50 more in the seller's pocket. That is money they can put towards their next home, paying off the outstanding mortgage or paying the taxes on the sale.

That said, a low commission is only a real saving if the service is complete. If you then have to pay separately for the valuation, the energy performance certificate, the paperwork or a lawyer, the comparison changes. The useful question is not “what percentage do you charge?” but “how much will I pay in total, and for what?”.

Who pays the estate agent's commission and when it is paid

In home sales there is no rule saying who must pay the estate agency: the contract decides. In Madrid, the seller usually pays, as the one who commissions the service. In its 2026 survey, the OCU did not find any agency in Madrid that also charged the buyer, something it did see in Barcelona and Seville.

When you pay is as important as how much. According to HelpMyCash, the most common practice is to charge on signing the arras (deposit contract), or half at the arras and the other half at the deed; only a minority charge everything on the day of signing before the notary. RealAdvisor also describes a 50% split at the arras and 50% at the deed as common.

Why does it matter so much? Because weeks or months can pass between the arras and the deed, and the deal can fall through: the buyer does not get the mortgage, an unexpected charge on the property appears or one of the parties pulls out. If the commission is paid at the arras, the seller may end up paying for a sale that never happens. The OCU recommends agreeing that fees are not paid until the deed is signed.

A tax tip: keep the invoice. As RealAdvisor explains, referring to the Agencia Tributaria (Spanish Tax Agency), the commission is deducted from the transfer value when calculating the capital gain for income tax (IRPF). Your adviser will tell you how to apply it in your case.

Double commission: when the buyer pays too

We speak of double commission when the agency charges the seller for selling and also charges the buyer for buying. The OCU documented it in its 2026 survey: in Barcelona and Seville, several agencies charged the seller between 2% and 6% and the buyer between 2% and 4% or a fixed amount. HelpMyCash also reports charges to the buyer of around 3% plus VAT.

In Madrid, the OCU survey did not find this charge, but that does not mean it cannot happen: the sample was limited and conditions vary from one office to another. So if you are buying at the same time as selling, ask in writing before the first viewing whether the agency will charge you anything and for what.

Double commission raises two problems. The first is financial: the buyer adds several thousand euros to the taxes and costs of the purchase itself (we go through them in “Costs of buying a home in the Comunidad de Madrid”), and this also affects the seller, because what the buyer pays the agency is money they cannot put into their offer. The second is about trust: it is hard to argue for the highest price for the seller and the lowest price for the buyer at the same time. The rules do not set who must pay, but they do require transparency, as we will see below.

Hidden costs when selling a flat: what is not always mentioned at the start

The OCU's January 2026 survey paints a clear picture of missing information. Only 5 of the 60 agencies consulted provided a sample listing agreement when first asked for information. Some did not specify when the commission was paid, and it was common to advertise it without VAT.

On top of that come services that may be invoiced separately. These are the items it is most worth asking about before signing:

• VAT on the commission (21%), if the percentage was given “plus VAT”.
• The energy performance certificate, needed to sell: the OCU found prices between €60 and €150.
• The nota simple (Land Registry extract) from the Registro de la Propiedad and the community of owners paperwork, if the agency obtains it and charges for it.
• Photo shoots, video, floor plans or virtual tours, when presented as “extras”.
• Later formalities: cancelling the mortgage at the Land Registry, calculating taxes or accompanying you to the notary.
• Amounts for withdrawing from the agreement or for not accepting an offer, which we discuss in the next section.

None of these items is in itself an abuse: many are real services with a real cost. The problem arises when you are not told about them before signing, or when they are presented as included and then turn out not to be. The OCU asks that basic information include the commission, the expected sale price and a breakdown of fees for additional services.

Penalty clauses and automatic renewals in the listing agreement

The listing agreement is a contract and, as such, may include obligations for the owner that go beyond paying if the property sells. HelpMyCash lists situations in which the agency can claim the commission even if there is no sale, or even if the sale comes later: when it introduces a buyer who accepts the agreed terms and the owner decides not to sell, or when the buyer introduced by the agency completes the purchase up to a year after the contract has ended.

The OCU also points out that contracts may include tacit renewals or notice periods for ending them. If you do not give notice in the time set, the agreement renews itself. It is a detail that is easily overlooked and worth noting in your calendar on the day you sign.

The Ley General para la Defensa de los Consumidores y Usuarios (General Consumer Protection Act) limits these clauses when the owner contracts as a private individual and the text has not been individually negotiated. Its article 82 considers unfair any non-negotiated terms that cause a significant imbalance in rights and obligations to the detriment of the consumer. Among the law's examples are imposing a disproportionately high compensation on anyone who does not comply (article 85.6) or creating onerous or disproportionate obstacles to exercising rights such as ending the contract (article 87.6). Whether a specific clause is unfair depends on each case and, ultimately, is decided by a judge: if a penalty seems excessive to you, get advice before signing.

Inflated valuations and pressure to lower the price

One of the most striking findings of the OCU survey directly concerns Madrid: all the agencies consulted in the city overvalued the property, by between 5% and 10% according to the organisation's estimates. In Barcelona the valuations were closer to the mark, and in Seville they tended to fall short.

A high valuation sounds good when you sign, but it comes at a cost. If the flat goes on the market above what buyers will pay, it gets few viewings, the listing goes stale and, weeks later, along comes the recommendation to lower the price. Sometimes that reduction is good advice; the problem arises when the initial valuation was inflated to win the instruction and the owner loses time and bargaining power.

The 2026 context makes this point more delicate. In idealista's survey of professionals for the third quarter, reported by Merca2 in July, 16% of agencies expected prices to fall, compared with 6% the previous quarter, and 26% expected fewer sales. Asking the agency for the data its valuation is based on (actual sales of similar flats, not just asking prices) is the best defence.

Unverified buyers: the risk of the sale falling through

Another frequent source of trouble is accepting an offer without knowing whether the buyer can pay. If the buyer signs the arras and the bank then refuses the mortgage, the deal falls through, the flat goes back on the market some time later and, if the commission was paid at the arras, the seller may find the agency claims it anyway. HelpMyCash expressly warns of this risk.

There are no public statistics on how many sales fall through for lack of financing, but the risk is easy to reduce. Before accepting an offer, ask for proof of financing: a recent bank pre-approval or evidence of enough savings for the part the mortgage does not cover. Also check the identity of the person signing, and ask the agency, before hiring it, how it verifies buyers.

What consumer law says about price information

Although commission is freely set, the information about it is not. Several rules require consumers to know the total price before committing. The most specific one for housing is Royal Decree 515/1989 of 21 April, on the information to be provided in the sale and letting of homes. It applies to the offer, promotion and advertising of homes aimed at consumers, and its article 6 is clear about the price:

Total sale price, which shall be understood to include, where applicable, the Agent's fees and VAT

Royal Decree 515/1989, article 6

In other words, the price presented to the buyer must include the agent's fees, where there are any. That is why the OCU asks for listings to show the total amount the buyer will pay.

For the owner who hires the agency, the General Consumer Protection Act (Royal Legislative Decree 1/2007) applies. Its article 60 requires the consumer to be informed of the total price, including all taxes and charges, clearly and comprehensibly, before they are bound. Article 20 requires commercial offers to state the full final price, and article 63 requires a receipt or copy of the contract to be provided.

Law 12/2023 on the right to housing added, in its article 31, a list of minimum information that anyone interested in buying or renting a home can request before completing the transaction and handing over any money on account. It includes the total price and the items it covers, as well as the financing or payment terms.

Is there a specific rule in the Comunidad de Madrid?

We have looked for a Madrid regional rule dedicated to information in home sales and have not found one. The region applies Royal Decree 515/1989 and national consumer law, together with Law 11/1998 on Consumer Protection in the Comunidad de Madrid, which sets out the right to know the total price including taxes and considers it an offence not to have complaint forms or to refuse to provide them.

What does exist is oversight. In 2023 the Ayuntamiento de Madrid (Madrid City Council) published the protocol for an inspection campaign at estate agencies that checks, among other things, that fees are disclosed in advance, that the client receives a signed document with the essential terms of the instruction, that there are no unfair clauses and that, in sales, the total price including the agent's fees is disclosed.

As for who can practise, in the Comunidad de Madrid there is no obligation to register in order to work as an estate agent. There is a voluntary Registro de Agentes Inmobiliarios (Register of Estate Agents), regulated by Decree 8/2018, which requires training or experience, civil liability insurance of at least €100,000 per claim and a guarantee of €60,000 per office. In June 2026, the regional government announced it will push for a compulsory register, according to idealista, although without dates. Catalonia, the Valencian Community and the Balearic Islands already require one, the OCU notes. Before signing, you can ask the agency whether it is registered and insured: not being registered does not mean it does a bad job, but it is useful information for comparing.

Checklist: what to review in a listing agreement before signing

Ask for the sample contract before committing and read it calmly at home, without haste or pressure. These are the points worth checking one by one:

1. Identification of the agency: company name, NIF (tax number), address and, if it has one, its number on the register of estate agents.
2. Commission as a percentage and in euros, with VAT shown separately and the final total.
3. When payment is due: better on the day of the deed than on signing the arras.
4. What happens if the sale falls through after the arras.
5. Services included (valuation, photos, listings, viewings, paperwork, arras, notary) and the price of any extras.
6. Whether the agency will also charge the buyer, and how much.
7. Asking price, minimum price and the data the valuation is based on.
8. Duration, automatic renewal and days' notice to end the agreement.
9. Penalties: how much you would pay for withdrawing the home, not accepting an offer or ending early.
10. The period during which the commission can be claimed if a buyer introduced by the agency buys after the contract ends.
11. How the agency will verify buyers' identity and financing.
12. A signed copy for you and no references to documents you have not been given.

If something is unclear, do not sign until it is clear. The terms of a listing agreement can be negotiated, and an agency that works transparently should have no problem explaining them or putting them in writing.

How to save on commission when selling your flat

Saving on commission does not take clever tricks, just careful comparison and clear terms from day one. These are the steps with the most impact:

• Ask for at least three proposals and compare them in final euros, including VAT.
• Negotiate: the gap between what agencies ask on average (5% in the OCU's 2026 survey) and what sellers said they paid in 2024 (3.6% plus VAT) shows there is room.
• Pay only if it sells and on the day of signing at the notary.
• Insist that everything included is put in writing.
• Prepare the basic paperwork yourself (energy certificate, IBI property tax and community fee receipts, nota simple) if they charge for it separately.
• Look for a realistic valuation from the start: a well-priced flat usually sells sooner and with fewer reductions.
• Keep the commission invoice for your income tax return.

Saving should not mean giving up safeguards. A sale also becomes more expensive if it falls through, if the buyer had no financing or if there is a mistake in the arras. What you should look for is a clear price and a service that covers those risks.

How we do it at Llavely

At Llavely we start from the problems described above: commissions you only find out about at the end, VAT that appears later, payments before the sale is final and buyers who may or may not be able to pay. With “Llavely Sale” you pay 2.5% + VAT, only if you sell and on the day of signing at the notary. Nothing up front and no minimum.

That 2.5% + VAT includes everything: specialist lawyers with more than 35 years of experience who review the nota simple, charges and debts, draft the arras, calculate the plusvalía (municipal capital gains tax) and income tax, prepare the deed, go with you in person to the notary on the day of signing and answer your questions; professional photos, video, floor plan and 360 virtual tour; a valuation against the market; the viewings, which we carry out ourselves so you do not have to show the home; anti-money-laundering checks, traceable payments and coordination with the notary. From your private seller portal you follow every viewing, every offer and the documents. Using the examples in this article, on a €450,000 flat you would pay €13,612.50 in total, VAT included. The only thing that is extra is the energy performance certificate, which is compulsory to sell.

For the buyer, Llavely is free: they pay nothing. Buyers are screened and verified by us: we speak to each one before showing your home, ask them how they would pay and check their ID before the viewing. We also check the identity and ownership of the seller. There are no extra payments or hidden costs for anyone: what you see is what you get. If you are thinking of selling in Madrid, ask for your free valuation: we call you within 24 hours, see the home and give you the price.
