Sometimes people that are in really big houses are also in really big debt. Therefore, IF something changes with their cash flow, their world comes crashing down.
There is a story here in southern NH from twenty years ago about a rich guy that lived in a big fancy house.
One day he went down to the Nashua airport, took off in his private plane, flew over to his house west of town and dive bombed the plane into the house. He killed himself and burned the house to the ground. Fortunately, his wife and son were not home. She wanted a divorce.
I had a neighbor with two new foreign cars and a nice house. The water company came by and did a little digging in a 10 x 10 area and threw down some seeds and straw and called it good. He was complaining to me that he didn’t have enough money after his monthly expenses to hire someone to bring it back to mature grass. Couldn’t believe it.
