I'm sorry that you're going through this. That's not necessarily true. Did you request the HOA minutes. Couldn't you have requested these from the seller? Didn't you have a right to rescind? These will all be defenses to your case.
Your statements are vague regarding what representations were made to you although that doesn't mean that you don't have a case. They could have been presented in a manner that would be a material misrepresentation. I really don't know based on the facts you presented and I haven't reviewed any of the documents or reports regarding your case. Did you have the property inspected before you bought it? As a real estate lawyer, I generally recommend that you spend the money to do it right the first time and hire a contractor to inspect the premises before you buy. Of course, that's not the situation here although you ought to know that for future reference.
Regarding your case, $27,000.00 sounds like a lot of money for major repairs. I would speak with a real estate lawyer in your area soon. There are certain statutes of limitations regarding your case and, if you do not act, you could blow the statute and jeopardize or otherwise waive your legal rights.
There are several highly skilled lawyers on Avvo, as examples. I would suggest that you hire one of them to see if you have a case.
