Extract: Learn how real estate agency fees are calculated and why expert local agencies like Nicolas Immobilier guarantee transparency, reliability and tailored service.

What are agency fees and why do they matter?

Agency fees represent the commission earned by a real estate professional for successfully handling a transaction. Unlike fixed rates seen in other industries, these fees are usually calculated as a percentage of the sale price, typically between 3% and 10% depending on location, services and the type of property. Their calculation influences the final price the buyer pays, the seller's profits and even notary costs. Agencies also offer fixed-fee options for certain situations.

Determining the percentage or flat fee

Most traditional agencies opt for a tiered percentage model. For example, a sale at €300,000 with a 5% fee means €15,000 as agency commission. As a seller, you may encounter sliding scales, where rates drop for higher property values. Alternatively, online agencies might offer a fixed fee—particularly attractive for high-value properties. The choice of exclusive or simple mandate and the complexity of your sale directly affect how fees are set.

Who pays the agency fees: buyer or seller?

Agency fees can be paid by either party, depending on what is agreed in the sales mandate. Most often in France, the buyer assumes the commission, which may result in lower notary fees compared to when the seller pays. Full transparency about who is liable is mandatory on all listings and marketing material.

What services do agency fees cover?

Agency fees cover a wide range of services:

  • Accurate property estimation and market pricing

  • Creation and distribution of listings on major portals

  • Management and scheduling of viewings, including virtual tours and professional photography

  • Negotiation support and legal administrative assistance until closing
    Clients benefit from added value when local expertise is applied, allowing for optimal pricing and reduced time to sale.
