Okay, when I bought a house during the last refi/purchase boom I made sure I kept every single email, letter, signature, etc. I am hoping you did the same? I mean actually I still have them and I bought my house in 06. If this is the case then you are fine, as you have details and facts. However if everything was via phone, text, etc. then he may try to file a law suit sure, but as Flounder stated, just threaten a counter law suit and I think he will walk away. One of the things about being on a public site like Zillow etc. is they have to agree to let people posts comments regardless of what they are. I work for one of the largest lenders in the nation, we get shit like this all the time, non-stop, and we don't do shit about it because there are so many other opportunities out there. This guy is the same way and I am sure just throwing out the law suit out there. A few things I noticed; 1)The guy looks like a DB, always use a hott female Realtor, a family friend that you TRUST and know, or some guy that is young. They seem to be the ones that get things done. Hotties will do anyone to get the job done, family friends don't want to disgrace their family, and young guys are all about $$. This Realtor looks like he stopped at a doughnut store then had BK deliver to his house all while he was threatening law suits at people and looking at gay porn.
