再问一下

"If you have a very credit /personal credit line, you can use that nmoney. I remember there is once a man who use his credit card money to start a company and sold to IBM a few years later."

Did you mean "If you have a very (good) credit"?
And when you say "You can use that nmoney", did you mean the money that I can borrow like "mortgage"?

Not sure if I want to get on the credit card, the interest is way too high.

Thanks.
