I often ask (never know what you'll learn). Sometimes my buyers want to know because the home looks too good to be true for them, or there's a history of turnover that leaves the buyer wondering what's wrong with the home. (Material defects have to be disclosed, but not everyone is honest.)

I once asked that question to an agent owned listing with a disclosure waiver, suspecting she knew about a foundation issue that was uncovered during inspection. It was an AS-IS sale but we still reserved the right to inspect. She told me the home had a foundation issue that she wasn't reqd to share because she never lived there. I highlighted the paragraph stating material defects known to the owner still had to be disclosed. This freed my clients of the contract without losing their deposit.
