I recently got a tour of an underpriced house that could easily be converted into a duplex. However, it would not be a side by side but, rather, a stacked duplex. I was wondering if anyone has had much experience with stacked duplexes and what the major downfalls are with stacked (specifically, noise issues)?
I was also curious with how effective sound proofing is and if it would add many costs in converting a single family into a duplex?
I would avoid converting anything due to the cost to make a new bathroom/move plumbing and electrical.
I currently have a stacked quadplex and I don't have any issues. If the tenant is noises that's a violation of their lease.
