Everything I own is for sale, ask me and I will give you a quote.

I have to admit that sometimes it is hard for me, but I try not to hold too many sentiments in things, because ultimately, it's the memories with the people that are related to the thing that matters.

Resale value is how much money can you get if you put the item up in the market for sale. The resale value is fair because it doesn't factor any sentimental or functional value, but just how much the next buyer will be willing to pay for.

So just because your house worth 1 million according to the market or your painting worth 10 million just because your mom says so doesn't mean anything until you can find a buyer who is willing to pay that amount.

If the product is illiquid (can't be sold), or you plan to give it away eventually
