How can I forget you have experience if I don't know you have? Very confusing, unless of course the French flag is your proof.
Figure of speech.
Perhaps my awareness of other relevant websites is a small clue.
Your experience is hearsay.
And your attitude seems to be "ne'er do well" so you try to deride others instead of a positive approach.
I don't try to deride others, some do a good enough job on their own.
Stating a region is the cheapest when it clearly isn't shows a lack of understanding of the topic in question. Giving false information is none productive and misleading and reflects upon yourself in a less than favourable way.
You are deluding yourself.
I give an opinion that the house is overpriced, supported by external reference. While you suggest that the house could be worth as much as €1.5M.
Can I suggest that you restrict yourself to areas of your own expertise, if there are any.
Your singular purpose on here, as far as I see, is to criticise others' comments.
Therefore, surely, you fit into JBR's image of a troll!
