Not about your reno - but about project management.
My FIL is in a care facility dying of cancer. He will never return to his home. He has lately started asking about major maintenance issues with the house, replacing the windows, exterior painting, etc. The plan that my DW and her siblings have is to wait until after his passing and see if the house should be sold as-is, the most common way with estate sales, or if the realtor thinks that certain deep maintenance would increase the profit margin. As the retired one who lives nearby, it would fall on me to oversee the contractors who would be doing the work. Since I think the house has too many deep issues (plumbing, electrical is no longer sufficient, etc) I think the as-is would be the best bet. For the moment we are stalling.
With my engineering background I know I can do the administration/oversite of the various contractors, but I would like to put that off until we know that we will not be selling the house as-is.
