Thanks again everyone,
I must admit that credit is not somehting i had really considered before, as the checks here in Aus are not as strenuous (payslips usually suffice). We do have an AMEX card so might have to get a US version of that
I will talk to work about an executive apartment or about them paying the rent. The move is indefinite from works end, from a personal perspective we are going to give it a yr and see how i am going in the role and if we like LA, USA etc etc, so in short, it will be minimum of one year, probably longer
