Commission rates are usually roughly the same between agents; they deliberately keep it this way. If you’re looking to complete a Barcelona property sale then you’ll probably be looking at between 3% and 5% of the selling price.
However, it is possible to find an agent that will charge you a fixed fee, regardless of what price they sell your property for. This means you know exactly what you will be paying before you even find a buyer. This can help you budget and allow you to negotiate easily with potential buyers.
A good real estate agent will be putting in a lot of hours trying to get your property for sale in Barcelona sold. If you are not comfortable with the commission they are charging you can always negotiate.
However, you need to do this before you agree to list with them. Once the agreement is signed the conditions will be locked in place for a set period of time.
