Andrew, when I came house hunting I got personal attention from an agent. It turns out she was working alone, having been sacked by the agency but still without her siret. Anyway, accidentally I called the agency and they blew a fuse. In the end it meant they we escaped the commission fees that she was setting higher than normal for both the vendor and us. Beware such scams. My OH, for lack of any of our regular work, is part time working for an estate agency. THis one is trying to play the game straight, not messing people about and ripping whoever off which some 'British' ones do and plenty of French agencies try. I know several people who have fallen into a trap by joining a 'sell it yourself' website and then paying really through the nose. Yes, Elaine is right about Connexions but its distribution is not clever and the other paper, which I used to buy each month for a while, folded last summer.
Angloinfo, Leboncoin and the like attract scammers, unfortunately, which is not their fault but criminals have to survive like the rest of us after all - unless it is us!
Brits ARE looking at France right now and come Spring should be back. Those with a bit of money to invest who are expecting UK prices to plummet are looking for 'cheap' properties here. Cheap is relative of course, for some of them €300,000 gets many times more than over there - like a small chateau instead of a flat in some cases. My OH has a few visits coming up. Now this particular agency are doing well and have plenty of French (and other) buyers and sellers, not just UK buyers like some of the others. They have been here a long enough time to know the form and field and not put all their eggs in one basket. They've also very cleverly worked out that French agents putting a union flag in their window and having one person who mutters a few words of English but has not a hope in Hell with regional accents which make for a loser.
I am not in the business of publicising the firm, even for my missus, but if you want to know and in order to look at their site or talk to them (worth doing always) e-mail if you want and I'll let you have their main coordinates. As for my nearest and dearest, she is too far away from your area to be interested so this is not on our behalf at all because their is no bounty for finding them people off own territory by such means. I must say, after her seminars with them, training and so on what she has brought home is revelatory and having dealt with two of our local agents before the British person I began with I am not impressed and would have originally reco'd avoiding agents.
Give it a thought, if it works that way, ask and I shall give.
