Bear with me, I was bored one day and typed the address of one of my neighbours into a well known search engine.
Although the double glazing and front door were as the council had installed them, they had bought their property and I found out a few other things too!
i wasn't bored but really curious and typed in a neighbours property, i knew it was private but not how much they rent it out for, fer crying out loud...
Alternatively, if the property has been sold since 1995 it will be listed (together with the price paid) when you enter the postcode here:
