Quitting my current job

[Elmer Wayne Fisher]

I currently own an SFR that is producing long term rentals, in fact I haven't even been to the house since I bought it 2 years ago. My management company is charging 8% but saves me a 1 hr drive when problems or basic maintenance arise.
 Regardless there is another house near lyn that I would like to buy if the numbers make sense, that being said if I buy this property it will most likely a lot of my time and energy ( and money ) to fix it up. 
  Would now be a good time to quit my current stable job and go all in on treating real estate as a business not just a side gig? 
  I’ve often wanted to own my very own business anyway. 

  Basically my question in a nutshell: at what point do you take the jump and say “I’m quitting my job and taking on real estate as my very own business?
