I have bought many collections or hoards of parts in the past. I have seen entire houses full of motorcycles and parts. Kitchen cabinets full of motorcycle parts not dishes. Many times there were dozens of bikes and not one running motorcycle.
A few years ago I got a call from a long time customer stating he wanted me to buy his collection. I drove to a small west Texas town about 5 hours away to look at the stuff. I had not seen him in a few years. When I arrived I noticed he had trouble with his hand trembling non stop. I am sure he had the beginnings of medical problems but I did not ask about it. He had a workshop full of good bikes, a barn with more project bikes and a shed full of parts. About 20 bikes in all. We were looking over the stuff when his wife went inside to get us some iced tea. As soon as she left he looked at me and said" Keith you have to buy this stuff. That women has put up with me and my motorcycles for 55 years and I am not leaving this stuff for her to deal with. I owe her that much." We did the deal that day.
I got a call about a collection of stuff not far from the shop and went to see it. The guy had died from a heart attack while sitting at his desk at work. He was due to retire the following week. The widow had a garage full of bikes she knew about. After he passed she had two people tell her that the guy had some bikes in their garage and then she found the keys to a whole other storage unit with more bikes and parts she knew nothing about. She was not happy about her husband keeping secrets.
My ultimate find was in 2008. This guy was a true hoarder and had great taste in motorcycles. Here is link to story about the collection.

Dealing with the family can be tricky as many times the person who has passed had been telling the family how valuable all the stuff is but the fact that nothing runs, missing titles, non matching numbers and other factors means that the value is not that much on the open market. Many times they think you are trying to get the stuff for cheap as they fail to see the facts and just want as much money as they can get. They go to the internet and see a Rapide for 50k and now the pile parts in the shed are worth 50k. Nothing you say can change their mind.
Got a call about a 1968 Triumph TR6 back in the 90's. A women was moving into rest home and she had a bike in the garage. They wanted 800 dollars for it. Drove over and nearly fell out on the floor when the door opened. Her son had went to Vietnam and never came home. It had 1600 miles on it and was perfect. It had sit in the same spot since 1969. I told her I could not pay 800 dollars for that bike but I would pay 5000. The tears in her eyes made the bike worth it. The bike just came in for service this week and still is one of my favorite bikes. I sold it to the right person that worships it.
The emotions that motorcycles can evoke can not be matched by many other things in this world.
