FL tax liens, Solo 401(k)

[David Morgan]

Florida tax liens look interesting.

1.) Does anyone have a recommendation for a place to set up a self-directed 401(k) with Roth? Or is this a bad strategy for buying liens?

2.) What happens to the liens that aren't bought in an auction? I see tons of them listed online in some counties, and it's well past the auction date. Why didn't someone snatch them up?

Thanks!
