What is the fastest way to retire, using passive income on real estate 
Rule of thumb: To retire with a yearly income of $X, you need to save $(20*X) -- in other words, the safe assumption is that you'll average 4% returns on your stabilized savings/investments. In the case of retiring with a $50k passive pretax income, that means you need savings of $1M by the time you retire. If you want the $50,000 to be real post-tax spendable dollars, and your savings aren't in something like a Roth 401k or Roth IRA, increase that proportionately to account for taxes. How you get there depends on what you start with, how much you put into it every year, how you invest it and how many years you have before your retirement date. Passive investment alone will not do it unless you start with a lot of money; passive ongoing investment may depending on how much you can make yourself save when. To find out whether any specific plan will do what you need, you have to work with real numbers.
