Would those numbers be real?
They are about to be right about dublin, the rent price is not right.
I rent a 3 bed house for 1150, outside city centre. 15km away from city centre and a good area
Site says 1700
Would these prices be correct if you buy in germany like in lorrach?
Another thing to take into account is education. You mentioned you have a daughter, how old is she? In Ireland you would get a decent free education in English whereases in Switzerland you may want to go for international schools which are expensive.
She is 1 year old.
I think she would go to a free school in CH
I cannot emphasize Rufus' advice enough. Do NOT assume that because you are an experienced software engineer that it will be easy to get a job in either Zurich or Basil. Especially if you don't know German! On another thread there's another guy who is struggling to find a job and he has a masters degree in physics. Look to see what jobs are available---and which employers are interested in you---before you come to Switzerland.
That being said, congratulations in advance of getting your new job. Welcome to Switzerland and the English Forum!
