You get what you pay for. We used them last time. Yes the house sold, but we did nearly all of it ourselves. I've bought and sold lots of times so that was ok, but if you're not experienced in selling homes, you won't get much help
Specifically:
Agents cover large areas so may have little local knowledge.
Pictures were awful and I was told that if we wanted quality pictures we should have gone to a professional photographer(!)
We explained we had a difficult neighbour so the for sale sign mustn't be put on their land. It was.
Once the initial viewings died down, we had to chase the agent and suggest a price drop, there was no proactive contact with us. She was impossible to get hold of most of the time. She eventually changed the listing to reflect the revised price and we received offers within days
We seemed to be expected to deal with all the negotiations on price ourselves.
Our agent said she had got proof of funds from the purchasers, I've no idea if that was true or not.
We never heard from her again after that point on.
I agree entirely about negative reviews being removed. Mine was, and I had to provide evidence before it was reinstated. I bet most people give up and don't provide the evidence, so most negative reviews are simply deleted.
Oh and my conveyancer said to never use PB conveyancing services as she always ran into trouble dealing with them. Our buyers did use them, and the service they got was desperate.
