近くに住んでるねって英語でなんて言うの？

There are many ways to say this one. You can say, "OH, I'm your neighbor", "that's where I live too", and "I live in that same area". You can also say, "I live near there", "that's close to my house", "we are neighbors", "I know where that is, it's next to me".

A common English saying to use when someone lives close by is 'just around the corner'. I could also use this in another context, for example - "The bakery is just around the corner from me." This may not always mean literally around an actual corner, but rather just implies that whoever you are talking to lives close to you.

A local, is someone who lives nearby the place where you are speaking - or who is a regular visitor of the pub/club/venue in which you are speaking.

Most of the time, when people realize they don't live too far from someone else, they just point out that they don't live too far away. There isn't much else that people say. This is a fairly understood phrase.

If someone lives close to you it is said they live 'near' you the term we use is 'nearby' A common saying for this is to live 'just round the corner'

If you are talking to someone for the first time and you learn that he/she lives very close to you, you could say a variety of things. For example, you could say "You live just around the corner from me". This is a common English saying which expresses that the distance is so close it almost like its just round the corner from your house. You could also say something more direct and state "I did not realise that we lived so close to each other"
