How to build a big credit line?

[Mary Jay]

Hey guys,

So some people have huge business credit lines , like 800K...

How do you build something like that?

I think I have about 20-30K in business credit lines at 2 banks . Should I call the banks and ask them to increase the credit lines?

1) Or how do you increase it?

2) also, how do these credit lines work? Let say someone has 200K in credit lines, can this person go and buy a 150K property using that credit line?

Thank you
