My wife sold her mom's house and I sold my mom's house as an estate sale. One of the things this means is that the the sale was exempt from some disclosures. That was because there are things we did not know about the houses because we hadn't lived in them, in my wife's case in 17 years, and in my case in 31 years.
My wife's house beyond that was a normal sale. An inspection by the buyer revealed some dry rot, which we fixed before the sale closed.
My mom's house, I was prepared to make repairs if an inspection found issues, however the buyer's offer specified they did not want to have an inspection, and that THEY wanted to buy the house "as is"
