BiggerPockets is a great resource to build your team and get started.If you have significant time then you can use sites like PropertyRadar & Propstream and even local newspapers to find foreclosures.

Many people try to avoid paying the 10% tax and many people advertise their STR's in newspapers, on craiglist and other websites.

Here in Orlando they use to post them in the news paper for a few weeks before the actual sale.

You may want to puts ads in newspaper, bandit signs or mail out to homeowner saying that you buy House or something like that.

Go to classifieds then legal notices, Look for "Notice to Petition Administer Estate Of"What your only paying for is the newspaper to get your probate lead....

Also, for Fulton county the list is usually post on the sheriffs page (although it's usually posted later in the month) The website is http://www.fultonsheriff.org/tax-sales.html.The liens are also posted in the online legal organ (newspaper) now being hosted on https://www.law.com/dailyreportonline/public-notic...They are usually posted a lot sooner on the newspaper than the sheriff.For Gwinnett, it is posted here https://gwinnetttaxcommissioner.publicaccessnow.co...and here (online newspaper)https://www.gwinnettdailypost.com/classifieds/sear...

The most recent it found me was a 2016 court case against the newspaper for publishing these articles... 

Local social media, fb marketplace, craigslist, storage finder apps, local newspapers, hang signs, etc.

But this is something your not going to find from headlines on  newspapers, looking at schools/crime rankings from the internet.

That is how the governments keep revenue coming in.Just because you read in the legal news papers that an owner is in tax sales, does not mean that the property will, go on the auction block.There are times, when a property owner is late paying a lien that their name will appear in the papers.
