Regarding the Keperra house, my hubby would remove all the ceilings and walls and redo the wiring while he is at it. Is that overkill or just a darned good idea since, if we were to get it, it would be as a long term hold?
As for road noise (our biggest bug-bear) I have found that if a house is lower than the road, the noise isnt as bad as if you are higher than it. I dont know this particular house, but in that area they tend to be lower.
If you go to the trouble of removing existing wall and ceiling lining then take the opportunity to insulate all the external/internal walls as well as under floor and ceiling.
I did this on a townhouse that was an IP but now a PPOR. It was worth the effort ... The place is totally soundproof and you can heat it in winter with a candle .... I also insulated between floors ... makes a big difference to noise from upstairs.
