its discussed here that exponential jumps is key to building the cash flow and financial freedom, if you have, say 300k liquid, how many jumps should one make to jump levels, I have flipped properties in the past, but never really held because I got hit by the 08 Crash. Of course, short term rentals and other asset classes are of interest to me.
