oki am 100% sure that the financial iniitsuttons will not require a personal guarantee but that is only because I know which accounts to apply for. With respect to corps and LLC, last year I applied to the same company for a LOC about a month apart with 2 separate companies that I started. The LLC received a 5k like and the Corp received a 12K line. But remember, this is not a rule but using a corp just increases the chances of success and thats what the Business Credit game is about.
