So if you are owed $23.4 on a $130 lien (18%), and someone pays $300 for it, then they are happy with an 8% return (23.4/300).I know NJ also has unique rules around the winner in certain circumstances getting the right to collect interest on subsequent tax payments without having to go to auction.

Tax lien investors will sacrifice not earning any interest on the front end but make it back on subsequent tax liens.

I'm looking for something to go on a slide bullet point.
