An older person advises a younger one that that apparently very cheap old rotted house (with years of poorly done repairs executed by a variety of amateur repairers and fly-by-night gypsy home contractors, many repairs of which exacerbated the decay) is too far gone and trying to fix it is going to be a waste of money that will lead to a loss of time and money invested. They'd be better off in the long run looking into some totally different better house, or if they must have that house and location, knocking down the rotted house and building a new one that looks like the old one but which has a coherent and efficient modern infrastructure underneath the gingerboard.
The younger person then will always say, "OK, boomer, so you think better things aren't possible. Whatever, cynical grandpa!", rolling their eyes. The old person shrugs because he expected nothing different. And the young one finalizes that purchase of the house and they set to being the latest owner that's going to fix it once and for all and maybe even flip it for a profit. Decades later, the house is worse off than when they started and they are broke.
