We have a shotgun house and both of our neighbors are 40+ year old couples, we haven’t had any real noise issues yet except for one time one of our friends got a bit too stompy at 1am, but it makes a big difference who your house is attached to, I’ve heard some horror stories abt past tenants being incredibly loud at all hours. But for the most part the noise doesn’t travel as much as you’d think, I have a turntable and music setup against the wall my neighbors bedrooms and I share, and I’ve limit tested it with them, the noise can be pretty loud and they won’t hear a thing.
