Can a "Right of Redemption" be bought and sold ?

Oregon : Trust Note : Judicial Foreclosure: Right of Redemption

Oregon has 180 days for "homeowner . borrower" to redeem.  I know this doesn't happen a lot but I heard a crazy story .... Could it be true ?

"Investor" buys the homeowners "Right of Redemption".  If an flipper puts work in the house the owner of the "Right of Redemption"  buys back the property during the 180 days.  This gives them the title to the fixed up home at the auction price + what ever they paid for the Right of Redemption.

I think this falls in to the " Wrong but Legal" category.

Anyone else out there have experience with this ?  Is it preventable ?  How in the heck would a lawyer write up a contract for something like this ?
