Probably the refrigerator. We don’t have any high-end jewelry or electronics. Our art is just stuff we like, none of which is worth more than a few hundred dollars. I have a Franklin Mint Collectible vase that my grandmother had bought as an “investment” - I’d bet it’s still not worth as much as she must have paid for it.
Or maybe the dining room furniture. It’s 7 years old, but it cost a couple thousand dollars or so. Although I doubt I could sell it for $1K today…
