Bttrfly - adrenal support. I know you know what to do.

And get help with clearing out the house. It’s too emotional to do yourself.

I know you don’t want to clutter up your own basement, but I’d consider boxing up all the small stuff that is not clearly stuff to donate or sell , as you can go through that stuff more carefully one box at a time in the comfort of your own home at a later date. Move any furniture pieces you want to keep to your house then sell or donate the rest. Don’t keep any furniture for son unless he specifically requests it - too many think kids will want grandmas furniture when they move out but they rarely do. Then get the estate sale people in to sell everything, and hire a cleaner to come in and prepare it for renting.

Don’t try to sort everything before the estate sale - it’s too much, and too emotional, to go through all the small stuff. Just get it out of the house to address later and move forward quickly so you can start collecting rent. Enlist the help you need to get started - son, friends, etc.
