Build LLC credit with cash secured credit line

[Ian Landy]

Has anyone played around with setting up secured credit lines with banks where you secure the credit line with cash for the purpose of building credit. For example setting up a secured credit line of $95-$100k and secure it with $100k cash. Yes you will pay maybe 5% extra to use your funds, but in the end won't building the LLC's credit and having future opportunities to leverage that $100k you started with out weigh that interest payment?

If you have heard of doing this or done it yourself please chime in. Bank recommendations would be appreciated as well.

If you purchase property on this type of credit line can it still be considered a cash offer?

Thank in advance for your help!
