Yes please - and also why people should be "aware of giving power of attorney to estate agents" - it is far preferable in most cases to giving it to the builder/developer, what with the builder/developer being able to get finance secured on the property and the agent not. An agent would never sign on behalf of a client to take a property into their ownership while it holds a debt. Unless you know different.
Not trying to start an inquisition of you here - my heart goes out to you - I just hope you can give details so people have all the information they need.
