The property was in her childrens names since the early 80's. She passed away in 2016 and we sold the home in 2017 (home on market for almost a year before sold). I know we will get a 1099-S at year end. My question is whether it will qualify for the home exclusion on the gain? This home was not a primary residence for any of her children. If it doesn't qualify for the exclusion, how do I come up with a basis. I have no records for when my parents built the house.
Thank you.
