strictly an anectdotal observation based on friends who’ve sold..
Move about 90% of your stuff to storage. Have the barest minimum to “stage” the house, and live in it as a staged house.
All personal photos, kids toys, any art work that isn’t 100% bland… take it out. Take out 1/2 of the furniture to make it look more spacious. Make sure nothing is on the kitchen counter. Even hide the toothbrushes and other stuff that ends up on bathroom counters.
