Judgement lien options on real estate

[Pauline Jones]

I listened to a course by Mike Allen on buying discounted judgement liens options for $1

and then cashing them in when property is sold.  Has anyone done this?

He makes it sound so easy but I tried to find county records and there are

hundreds of thousands, the ideal is to find a property that is in contract

and option the judgement at a discount...too good to be true??
