Oh man, so sorry to hear about your mom IH, that's terrible! At least she went quickly and with little pain, it's a small silver lining but it's something.
I was executor for my grandmother's estate. I was handling it from 250 miles away. Her place was also a mess. We spent a week going through everything and throwing stuff away, giving stuff away, determining what we wanted to keep and what would go in the estate sale. I hired a person that specializes in estate sales and let her handle that part of it. Her place needed a ton of work but we elected to sell it as-is. Of course we got less for it, but in my opinion it was well worth the loss to not have to deal with renovations for months. So you might consider that. Consult with a realtor and find out how much it's worth as-is, and how much it would be worth renovated. Evaluate that against the renovation costs to decide if it's worth messing with. Good luck!
