So, yes they are legally required to disclose all known facts about the house called the seller's property disclosure.  

Very unlikely yes, but you get my pointYou should be at a minimum initialing every page on that original contract along with any other documentation (HOA addendum, seller disclosures, etc) to make sure you know exactly what terms you are agreeing toTypically the wholesaler is trying to conceal their fee.

Full disclosure, I'm a mortgage broker.The real answer is that it depends on your situation. 

Your local/state laws will dictate what must be disclosed but in order to avoid liability it has always been my practice to disclose EVERYTHING.Your contract should have either a section on the form itself or an addendum for disclosures.

My name is Luis and I recently began my venture into wholesaling here in Texas.After doing all my due diligence about wholesaling in Texas (learning the rules of disclosure, assignment and using the correct contracts, along with the appropriate language) I began driving for dollars and making phone calls.I came across a property that looks to be a killer deal after speaking with the owner, but I am not sure what the repair cost would be or if it would even be worth repairing.
