That is a very good idea Dragon. When I think of collateral I lean towards property as that would tie into the financing thing. Although, in not sure that it would fly with some residents.
Several residents have been very successful in getting others to loan them money (called "deposits"

by starting unregulated "banks" in SL. Some have even started stock companies that sell stock for Lindens, and supposedly invest the capital raised in land or businesses (usually casinos and night clubs).
There are multiple threads on the pros and cons of this. Just search the forums for "bank" and you'll find them, ranging back for years. Some are about particular in-game banks, others about the theory. That should give you plenty to think about.
Because SL banks are not regulated, audited or otherwise controlled, opening a "bank" is a good way to take others' money, convert it into US dollars and then leave the game. If you search in the forums on "Ponzi", you'll find many threads warning of this risk. A fellow named Ponzi is famous for the original "Ponzi scheme" in which a fraudster promises people high returns on their investments, and pays the dividends out of money received from the latest suckers. Eventually, the string plays out and the fraudster has to leave town in a hurry (with the money, of course).
Collateral is challenging, because the only thing in game that has real value is land, which has high carry costs. Various "land barons" sell parcels "on credit," using the same method as car dealers ... if you don't make the payments, I take the car back. For third parties wanting to be banks, the technical issues are daunting, and the carry cost that must be paid to LL for holding collateral is high.
For an extensive discussion of the issues of enforcing contracts (a loan is just that, of course) and potential solutions, there is a white paper and discussion in the Political Science forum, "Towards a Theory of Enforcing Contracts, Resolving Disputes and Incorporation," at:
