Which real estate strategy works best to escape the 9-5 rat race?

[Rodney Love]

My question for anyone that escape the 9-5 rat race is. What real estate strategy did you use?  Example if you had between $20,000-$70,000 to invest in real estate.  How would you use that to replace your income of  $7,000 a month from your job? Fix and flips, tax liens, mortgage notes,  rentals,  Airbnbs?
