Give me a museum and I'll fill it. (Picasso) Give me a forum ...
If you decide to have a "life garage sale", your furniture, pots, pans, stuff in the garage, stuff in the attic is likely worth something. If you include TVs, computers, smart phones, tablets, guns, art, you may have a pretty good amount tied up into those items. Is it easy to get the money out? Maybe or maybe not.
After a house, a car is likely most peoples largest expense. Yes, the value goes down, but a car worth $20k is certainly part of your net worth.
A pot may be worth $2, so your level of tracking might only go down to $1,000 or higher. Or have a bucket like "Household Items".
Back when I had nothing (literally) my car WAS my NW. Now, I don't even think of it as part of NW. BUT this is a good exercise. I think it's good to know what we value and % of NW may (or may not) be eye opening. We've done this exercise with house value as well, even though most do not include house value in NW.
Again, the exercise might be useful in evaluating our priorities while it really has nothing to do with NW as we here think of NW. YMMV of course.
