It would probably be easier to get the loan if you had an open line of business credt. The thing about revolving credit is that just because you have it doesn't mean you have to use it. Pick the card/LOC with the best terms AND benefits (because alot of them now offer incentives and programs that are beneficial to small business needs) and just keep it available in case you ever need it.

Good luck and if you need any further advise , feel free to email me.
