Quietly said, No, no, and no. Your job here is honoring your mother's memory, her life, and her "possessions" and estate. One would love to keep everything as it is or was, with no changes at all, hoping against hope someone will just walk in the door like nothing happened except a long vacation.
But that's not how it is unless there's resources to do so and create a time capsule, museum, or memorial. I don't know if you and your mother ever talked about the future without her (most families seldom do), but she entrusted you to make the tough decisions about what was important and material to her that she accumulated and was given throughout her life. That is a very big responsibility, and I'm sure it weighs upon you a lot because it creates all kinds of mixed feelings. And even with a will or living trust, where some or most of it is (hopefully reasonably) spelled out, there can and will be some obstacles via family and others. You'll have to navigate those as best you can, again hopefully with some guidance and help by legal representation, some negotiation, some prayers, and yes, even some quiet time discussions with your mom or at a graveside visit. I know its so soon but I'm confident you still hear your mother teaching or guiding you, or saying "whatever you think is best, I know you'll make the right decision. I love you."
For many of us, God owns it all. He gives us the opportunity to manage and shepherd those resources He provides us with, and when He calls us back, he wants those resources to help others, be it family, friends, or strangers. That help may come as reminders of a live well lived, the love that was given by God and reflected in your mom's life, or the material aspects to help someone else have something they didn't have yesterday. The important thing is to hopefully have your mother's spirit and intentions in mind, and know that she would be happy with your decisions.
"A house is still a home" and a house empty needs a new family to love it and fill it with joy. It is the cycle of things young and old.
