I forgot to mention...
Runser immo in Saint-Louis

Jacky Runser speaks English pretty well..he could understand me pretty well which surprised me because I'm American and most French people aren't used to an American accent.
He's also a friend of my husband (no business relationship whatsoever) so he's a good guy too...
We just recently bought a house so I've probably talked with every real estate agency anywhere near the French-Swiss border.
And in case anyone was wondering...he didn't ask me to post this...
I just thought it might be helpful to anyone who is looking to rent or buy something just across the border in France...
You know...you can get some good deals that way sometimes...especially if you have trouble reading the French real estate ads yourself...
