Soundproofing?

[Brian Kehoe]

I'm curious if anybody has ever had an existing apartment soundproofed before? If so how was the process and was it worth it or not. I have a great tenant with three young kids who lives above me. You can hear a good amount of noise from the kids running around. I know kids are heavy footed and it would be next to impossible to not hear them. My dilemma is I'm looking to move out soon and buy another multi family but I'm worried about not being able to find somebody who wants to live below three young kids. They're great tenants, always pay on time and never bother me at all I would hate to lose them. So I'm wondering if investing in some type of soundproofing would be a good idea or not.
