Speaking from experience of the death of close family member - if there is no external reason to hurry through the next tasks do them at your own pace, Wolf. You will know when you are ready to do the next thing, and what that is.
I know my current situation is different, in that my mum is still alive, but I am pacing myself in the disposal of her effects, and glad that I am not (yet) being hurried out of the cottage we rented (and are still renting) for her. This has allowed me to do things my way - starting with things that didn't matter, given to people who would return them if, miraculously, my mother returned to normal. Only this week have I begun to do things that are irreversible - selling stuff, taking stuff to the charity shop [thrift store], throwing stuff away, packing up things which define her as a person to send away in the hope that they'll be useful in the future to others with similar interests.
Of course, with momwolf living in your flat, you have different considerations - but this is a time when you should be gentle with yourself. Listen to your heart and be guided by it. Be kind to yourself.
