Maybe a tad on the high side, considering the source is a recruitment agent that have their fees entangled in these numbers.
Still, interesting to see how UK agency is so badly paid. Surely such levels won't attract over-achievers to the industry.
In the US, it isn't uncommon for real estate agents to earn 6 figures and the best (especially in New York) can earn 7 figures a year in commissions.
Food for thought, in the UK's estate agency race to the bottom in fees and service levels.
