I believe there are a number of fancy home furnishings that can fall into this category-
The basement sports bar. The piano. The pool in the back yard. The water feature.
I am enamored with the thought of creating a basement sports bar- but the reality is that it would become a dusty accumulation of junk. For the few times that we entertain, we can walk down the street to several sports bars.
We considered moving a piano that was DW's childhood piano. It was nice, and I'm sure it was a significant outlay for her family. The reality is that it is a dust collector. We decided to let it go, and our kids found a family that really wanted a piano. I told my wife that if she still wants one, we can buy a nice electric piano/keyboard. (Anyone want a player piano? We still have one of those in the basement of the old house that our son is buying from us...)
They key is- don't spend the money on things in the first place that you will end up spending money to get hauled away later. That is what we learned from cleaning our parent's houses, and cleaning out our own junk when we moved.
It is tough letting go of things that you spent good money on, especially when the value went to zero or below. Anybody need a set of encyclopedias?
