private lender money ?

Im after money to do short sales with banks ,also i deal with people having mortgage problems that will sell to me at a discount also.
Discounted properties is basically what its all about,banks take too much time to get different deals done. The security for the lender would be that they can own the title and all i do is control the property for a certain amount of time ,if i default they have a property they can sell and make even more money.
This is comon practice in the US and im just wondering if any one does this over here,or is aware of it.
cheers

Thanks for the advice.
But surely theres people out there that would take high intrest rates to off set risk,or share part profits,or am i just crazy to think this?
As in if i found a property for 80,000 worth 100,000 for simple terms,wouldn this be more secure than me buying it at retail for 100,000 with 10% down,makin the risk for the lender still 90%.
am i missing something?
This is called hard money,which im positive youve heard of .Is this type of funding difiicult to find here?
cheers
