I would be incredibly surprised if what you suggest was even remotely common, to have it happen twice is almost beyond comprehension!
I worked as an estate agent for over 20 years, at time for a large multi-national PLC, other times for a large multi office independent firm, not currently a partner in a single office operation. I've genuinely never heard of a colleague or someone in another firm nearby selling a property to a mate/relative on preferential terms.
What is far more likely is that once an offer has been received, even if a property has been on the market for several months, is that the EA will call other prospective buyers who have viewed, or expressed interest to let them know an offer has been put forward. Sometimes this encourages a viewer who was sitting on the fence to commit to an offer.
I'm not for one minute suggesting there aren't a very small minority of dodgy EAs, and certainly a larger group of annoying ones, but to suggest this is common practice is simply untrue, imho.
However, it is a lot easier to accuse the EA of being dishonest, like the OP on this thread chose to accuse the EA of "playing games" when they have presented not the remotest indication of any games been played.
