Hybrid estate agent Purplebricks has released a series of online adverts on the video sharing website youtube, which in some cases mock traditional estate agents.

The five videos, posted last month, have racked up nearly 4m views between them.

The short clips each address a question about the agent.

One, which has had just over half a million views, features a woman who asks: “OK Purplebricks, if you don’t have any branches, does that mean I have to do everything myself?”

A voiceover responds that Purplebricks’ Local Property Experts “can manage every aspect of your sale, wherever and whenever you need”.

It adds: “We think that’s far better than them twiddling their thumbs in an office on the high street.”

In another video, Purplebricks is asked: “Why should I take a risk with selling with someone new? Shouldn’t I just stick with one of the big dogs?”

The voiceover replies with “oh, we agree”, before going on to claim that Purplebricks is one of the biggest estate agents in the UK.

Other videos include questions such as: “How can you charge so little?”

Another asks: “Why bother to get the best price when you don’t charge commission?”

And a fifth video poses the question: “How can you give such great service when you charge so little?”
