Other options include borrowing from your retirement plan if that's an option (it might not be wise but it is an option)

I remember back in 2007 when real estate was booming -- but borrowers were getting no-doc loans and people without income or assets were leveraged up to their necks.A couple years later, everyone was saying, "I'm not sure how it wasn't obvious to everyone that the market was broken and it all had to come crumbling down?"

For example, I know that you can borrow against your 401k for a penalty, and I'm wondering if there are any similar fees/penalties for setting this up?

You may also be able to borrow money from your 401K. 

So I would be borrowing $80K. 

At this point, an entity I created purchased the non-performing note from a private lender who originated the note.Because the borrower wasn't required to make monthly payments, we had to wait until the note maturity date to start the foreclosure process.

The other thing you could do to make your own money go further, is to couple it with a private money loan on a purchase, but with you as the borrower of the loan.

Any advice on how to get leads to borrowers??

Lets say you borrow hard money at 5pts and 12%. 5 points just means you get charged 5% of the loan amount as a one time loan origination fee! 

Can you borrow against your brokerage account?
