just cheaper and when done properly is not a big deal, the only issue is just the permits needed to go from point a to b because a crew has to move lines, maybe even temporarily remove traffic lights, etc it's rare that people do it, but when they do it's because the house might be old and historic or it's a family heirloom someone is rich enough to move somewhere else. it's cheaper to build another home but that's not the folks doing it
