Has there been any news or stories of Bitcoin being used as collateral for a real estate purchase? I know it has been used to make the actual purchase but what about as collateral?
Given the nature of the block chain (ie. public ledger), it would be easy for a real estate entity to confirm a signee's Bitcoin ownership has not changed while still staying in possession/control of the signee.
I think the new US regulation will open up a new world of 'Bitcoin as collateral' and less so as a 'currency' per se.
If you use bitcoin as collateral then it would need to be possible for the lender to be able to seize your coins in the event you are unable to make your loan payments.
My question is how would the lender seize your coins? Unless you transferred your BTC to an address that the lender controls they would have no way to seize them. Even multisig would not work as collateral would be seized without the "consent" of the debtor (as they would have consented when they signed the loan agreement pledging the coins as collateral).
