My post is not a rant at estate agents (although they are clearly part of the problem), but a genuine query as to why people aren't protected from unscrupulous, disgraceful behaviour.
Wouldnt the Scottish system just bring your disdain further back just prior to the aforementioned Scottish 'agree a deal' stage if they then backed out at that stage in that country and why is the later 'agree deal' stage (exchange of contracts) here in England deemed by you so inappropriate in comparison ??
Serious question.
