We have finally found a flat we love and have put an offer in and our mortgage application has been submitted. It is in a purpose built on the mid floor from the 70s- we have neighbours upstairs and downstairs. We returned for a viewing yesterday with a builder, a Saturday morning, and we could hear child stamping upstairs. We asked the current tentante how the sound travels and they said other than the noise from upstairs it's pretty quiet. They said upstairs they have a little kid and sometimes can hear him in the night. We couldn't hear any voices or other sounds other than the child running around. The estate agent was present and we stupidly didn't ask more questions about it! Now I'm getting worried that we may be making a very expansive mistakes if we went ahead. We are also expecting a baby and our life is not going to be quiet Saturday mornings anymore so maybe we won't be that bothered as we'd have our own child making noises. We have a surveyor visiting Tuesday and we wanted to ask him to keep an ear out and maybe to pass us onto the tenants to cheekily ask them some more questions. We have emailed the estate agents with some more questions from the tenants as well about the frequency of the noise, whether it wakes them up at night etc but I doubt we'll get sufficient info from the estate agent! The tenants have lived there for 4 years, that's a good sign I guess.
I need some advice on how I can investigate the noise pollution into the day further before we commit to this flat.
