For estate planning, you can leave assets to your heirs through thoughtful estate planning using trusts and LLCs.My advice is to check out the book "Start Your Own Corporation: Why the Rich Own Their Own Companies and Everyone Else Works for Them (Rich Dad Advisors)" by Garrett Sutton (Lawyer).

I feel like the question you are asking is how do I become rich enough or make enough money in real estate, stock market or whatever vehicle you are using to live my current lifestyle so that I can not have to work and leave the rat race.This is a very different question then the initial one.  

You should Google Rich Dad Poor Dad Tax guy, and get the book he wrote. 

I read the Rich Dad, Poor Dad book and I'm amped about acquiring assets.

Start by reading "rich dad, poor dad", "set for life", and "the house hacking strategy".

I fully second @Rich O'Neill.

Created by Joe Berlinger, the Emmy-winning director of The Ted Bundy Tapes and Jeffrey Epstein: Filthy Rich, Crime Scene, "The Vanishing at the Cecil Hotel" arrives this Wednesday, February 10.

I agree with both Scott and Rich, an LLC is the way to go, especially if you're doing it as a 50/50 partnership.

@Rich O'Neill Thanks for the response!
