My parents built new at retirement and purged A LOT.And when I say sorting through papers, I mean PAPERS...
I was down there yesterday running two shredders for six hours. I was shredding utility bills from the 90's...
I'm going to be fortunate that when their health deteriorates that the did that for me. Both of their parents left them with quite a burden document wise.
Also fortunate that when they did build, they chose a great floor plan, and they didn't do anything weird at all paint/cabinet/appliance wise that will make it difficult for me to sell.
