The house is full of belongings and needs work. Where do I even start?

Start with the belongings before the repairs, since clearing the home makes it far easier to see what actually needs fixing and lets a contractor or inspector move through the space freely. An estate sale company or professional organizer can sort what sells, what a family member wants, and what gets donated or hauled away. Brian can recommend cleanout and repair resources so you are not tackling both jobs alone at the same time.
