Finding Raw Land with Owners Who Owe Taxes

[KC T.]

Hi folks,

I ran across the podcast linked below:

http://www.sidehustlenation.com/the-best-passive-i...

It's about flipping raw land.  They discuss finding raw land owned by people who owe taxes on it and may be eager to sell, then sending them offers.

I'm trying to learn how to do this without paying to guru who talks about it in the podcast.  So far, all I am hearing about in my research is auctions on tax distressed land that has ALREADY been seized by the state.

Can anyone clearly explain to me how to search for tax distressed properties that are still in possession of the individual owners?
