Ways to leverage cash

[Ted L.]

Is there a loan product like this: I deposit a sum of cash with a bank and receive tiny bank interest of say 1-2%. They extend a line of credit that is perhaps double the amount deposited and then charge line-of credit type rates? I guess I’m trying to leverage the money I have available without having to go through the process of applying for a loan or paying mortgage tax every time I buy a property. Furthermore, this would allow me to more easily provide a proof of funds. I would think a bank would find this acceptable since they are partially secured.
