The iad France network publishes an annual maximum fee scale, not a fixed price list. This nuance changes the interpretation of the displayed percentages and complicates any direct comparison with traditional agencies or online platforms. For a seller or buyer looking to anticipate the real cost of a transaction in 2026, understanding the mechanics of this scale is a prerequisite for any negotiation.
Maximum iad Fees: A Degressive Scale, Not a Unique Rate
The official iad France scale, accessible on the network’s website, operates by price sale brackets. The indicated percentages are maximums including tax, meaning that the iad advisor can apply a lower rate depending on the signed mandate.
The degressive structure follows a simple logic: the higher the sale price, the lower the percentage. For properties sold up to 19,999 euros, the scale provides a flat fee of 10,000 euros including tax. Between 100,000 and 319,999 euros, the maximum rate gradually decreases from 8.4% to 7% including tax. From 320,000 to 699,999 euros, it drops to 6% including tax. Beyond 700,000 euros, the ceiling falls to 5% including tax.
This scale only concerns traditional real estate sales. It explicitly excludes commercial real estate, businesses, lease rights, VEFA, and VIR. A point that many comparative articles fail to specify, even though it alters the comparison scope with other networks.
Fees are the responsibility of the seller, unless otherwise stipulated in the mandate. In practice, a comparison detailing the iad fee scale 2026 shows that the distinction between seller and buyer fees directly influences the calculation of notary fees for the buyer.
iad Pricing Positioning Against Traditional Agencies and Online Platforms
The figures from the official scale do not reflect the fees actually charged. According to a comparison of agency fees published in August 2026, networks of agents like iad or Capifrance are practically positioned within a range of 3.5% to 5% including tax on transactions concluded in 2025-2026.
To provide a concrete order of magnitude from this same comparison: on a property priced at 150,000 euros, the observed rate is around 4.5%. At 300,000 euros, it drops to about 3.8%. At 500,000 euros, it goes down to approximately 3.5%. These effective rates are significantly lower than the maximums displayed in the official scale.
In contrast, traditional physical agencies average around 4.5% to 5.5% including tax nationally during the same period. The gap exists, but it narrows for high-priced properties, where traditional agencies also apply degressive rates.
Online agencies (Hosman, Homki, Imop) operate on a different model: fixed fee or reduced commission, sometimes below 3%. Their pricing promise is more aggressive, but the included services differ. A low fee may exclude handling visits, negotiation, or support up to the signing at the notary’s office.
What the Raw Comparison of Percentages Doesn’t Reveal
Comparing an iad rate to a Homki flat fee amounts to comparing two different services. Three variables deserve verification before concluding:
- The scope of the mandate: a simple mandate allows for direct selling, while an exclusive mandate does not. The commission accepted by the agent often depends on the type of mandate signed.
- The services included in the fees: estimation, professional photos, distribution on portals, legal support. Some networks charge for additional services.
- The responsibility for the fees (seller or buyer): when the fees are borne by the buyer, they are included in the calculation of transfer taxes, which increases the final bill.
iad Rental Fees: A Framework Capped by the ALUR Law
The iad scale is not limited to sales. In rentals, the network applies fees regulated by the ALUR ceilings, like any real estate professional. These ceilings vary according to the geographical area of the property and are expressed in euros per square meter of living space.
In 2026, the ceilings for the tenant’s share remain set by decree. Highly tense areas (Paris and nearby suburbs) apply the highest ceiling, while non-tense areas show significantly lower amounts. The owner’s share, however, remains free.
iad reports an average rate of 3.4% excluding tax on sales, according to the network’s communications. This figure corresponds to an average observed across all transactions, not a guaranteed rate. Field feedback varies on this point: some advisors apply rates close to the maximum scale, while others negotiate downwards to obtain an exclusive mandate.
Obligation to Display Fees: What the Regulations State in 2026
Since the decree of January 26, 2022, amending that of January 10, 2017, all real estate professionals must display their fees in a visible and readable manner, in their windows and on their websites. This obligation applies to iad advisors, even if they do not have a physical storefront.
The scale must indicate whether the fees are borne by the seller or the buyer and mention the amounts including tax. On real estate listings, the price must appear including fees with a breakdown of the fee amount. A seller consulting an iad listing must therefore be able to immediately identify the fee portion in the displayed price.
This regulatory transparency is a concrete comparison lever. Before signing a mandate, checking that the displayed scale corresponds to the conditions proposed in the mandate remains the most effective precaution, regardless of the chosen network.
The iad 2026 scale remains competitive in the segment of agent networks, with effective rates often lower than the maximums displayed. The comparison with traditional agencies or online platforms is not limited to a percentage: the type of mandate, included services, and the distribution of fees between seller and buyer weigh just as much as the gross rate in the final cost of a transaction.
