Hi Love. I'm sorry to hear this happened to you. For your information, most agents carry E&O, or errors and omissions insurance. We can't even work without it in my office, it's mandatory. I personally don't know any agents that do not carry it.
It sounds to me like your situation fits a claim perfectly. The agent erred. The agent omitted to let you know about the true condition of the floors. Ask the seller's agent for a copy of their E&O coverage for the broker they work with and file a claim via an attorney asap. The longer you wait, the uglier the situation can get. Don't threaten, bully, scream or holler. Just file the claim immediately with an attorney representing you.
Then they will know just how serious you are.
GOOD LUCK and please let us know how it turns out, okay?
