We advertised our house on three internet websites, (two of which we had to pay a smallish fee up front and the other we agreed via a "gentleman's agreement" to pay if it sold via that site). We also put the house with two local agents and told them that we had advertised on those sites and said we wouldn't put it with them if we couldn't sell it privately ourselves, should we get the opportunity. It was agreed within our contract that we could sell privately - which we did in the end.
The thing to be aware of is that if anyone contacts you via a website you've advertised on, you need to tell them which agent it is with as if the agent gives them details of your house, then it has to be sold via the agent - which will cost the buyer a lot more because of the commission so they need to tell the agent that they have already seen or got details of your house.
I kept a list of everyone who enquired via the websites and of all the viewers (we had 16 sets of viewers in all).
I kept the agents updated with progress, as requested. One agent (in Guéret) was very helpful and regularly kept in touch and brought a quarter of our total number of viewers to see the house. The other in Jarnages - well, we didn't hear anything else at all until we told her it was sold.
We sold within three months of putting our house on the market.
As Zebedee says, the Notaire will deduct his fees from the house sale amount and he can pay you either by a cheque or he can send it electronically to your bank but be aware there may be a delay of a week or so before it turns up!
Our Notaire's office also advised the electricity company that we had sold on that date and gave them the reading from that morning. He also advised the trésorerie regarding the taxe fonciere. You need to take your bills with you when you go to him so that he can give those offices the account numbers etc.
