I sued someone about 8 years ago because I bought a house from them and they had concealed a bunch of rotten wood in my garage. they told me it had all been redone, but in reality all he did was cover up the rotten wood with new drywall. They refused to fix it when I discovered it a week after buying it, so I sued them. Long story short, after almost a year and a half and paying the attorney about $5,000, we got about $15,000 back. It was the principle of the thing. I figure the whole thing cost them at least $20,000, but I bet they'll disclose everything they know about a house before they sell it next time.
