Hello , I’m a trainee outside the probation period. I raised such a sum around 2500-300€. My income is about 570€ net + extra earnings (Schiri) 150 a month. My brother meant that he would like to be a guarantor for me if I didn’t get a loan. He is a German citizen but lives and works in Switzerland. His earnings are about 4500 francs net. I live 30 km away from Zurich on the Swiss border, would the bank accept such a thing? Greeting
