Just adding what has already been listed. Looks like they did new windows throughout and slider or french doors next to kitchen. Probably did a new front door too. One bath got new tile surround and fixtures for bathtub. I think UCGal has a good estimate at about 30-50K.
I also agree that I would not like to pay 100K more for that amount of work. I don’t think the house would have sold for that low if it had a full kitchen.
