Frankie, I understand completely but I would like to say that a lot of the problems came about because the "estate agents" recommended a solicitor to use for the purchaser. Most of those were already in the pockets of the land owner/builder/agent and perhaps an independent (or at least out of town/area professionals) would or could have given better advice instead of looking for their commission!!!
When we came over here many years ago for a week or two holiday and looking around to buy, staying with a friend who had moved out a few years earlier, he said "every Brit over here is an estate agent" It's still true!!
I know it's no consolation to the people affected but what looks like a good deal isn't always, professional advice (especially in a foreign country) can always be reflected back to the "professional" ... same everywhere in the world : caveat emptor
