If you lend at 100% of FV, what type of safety net you have to safeguard your investment (the loan). If you hand over $1M in exchange for a $1M BG, and the borrower defaults, you must liquidate the asset (the BG). And, if you came to me and offered me the BG, there is a huge chance that I will offer you only $65 for the $100M BG, so I can turn around and sell it to another party at $75 and the buyer will then flip it at $90 or so.
So, what kind of business person are you? Not a good one. Unless, you are simply looking for potential victims and steal the BG and that would be 100% profit to you.
