You should do lots of research and drive by each property that you might bid on.It depends on the laws in your state as to how string your tax deed is.I have been very luck and now have a nice portfolio of tax deed houses.I am also currently litigating a tax deed property where the precious owner is trying to over turn the county issued deed.With proper research you can mitigate a lot of the risk.There is  lot of information on the BP forums that you can study on tax liens.

As the story goes, apparently Marcus was selling a house for him, and the house was pretty far away from civilization.

Then I'd have to go through litigation which will be very costly.

Now I have to go back to the drawing board, I am trying to determine if it's worth getting a lawyer in hopes that I can get a judgement against him and ask that he pay my lawyer fees (I'm not sure how that works since I have a civil case.) 

After two weeks, my guess would be one of the above.I've bounced off of this scenario more than a few times, and I've come to two conclusions:1 - They're going to leave you hanging, be late or not at all with the rent, try litigation, etc...and in the end be a vacant property...with late/missing rent payments.2 - ...and, my solution (see above) became a case of, "If you can't lose it, use it". 

I graduated in 2019 from Auburn University with a degree in Civil Engineering.

When you file the suit, you can file a court lien against the property notifying subsequent purchasers that it is currently bogged down in litigation. 

The tenant does not abide by the rules and is a potential litigant. 

It may cost money, but it will be done right without violating any civil or criminal laws.
