Borrowing private cash.

[Justin Fox]

So when borrowing money you have the interest rate and term.  What are some other 'perks' in an investment contract the private money lender will look for or consider standard?  I guess an example would be an early pay-off bonus?

I know this is vague and subject to individual deals but some examples and explanations would be awesome.  A link to a really good book would be great too.

Thanks,

Justin
