Getting a Collateral Loan.

I have some money coming in but it might be a week or so.  Rent is due.

I'm thinking of putting up my car for a collateral loan.

What would you recommend is the best way of going about this?

 I recommend you call the landlord and ask for a one week extension. I can't see a good reason to go through the whole collateral loan process given the relatively short time frame before you have income.
