I bought 4 properties in the absolute bottom of the market cycle, fixed them up by myself and turned those properties into 8 rental units. Took me 2.5 years of 80 hours per week. When I was done it bought me approximately 8 years to figure out what to do next before the rules would change. Usually that's the amount of time you get until you need to reinvest. This allowed me to study bitcoin full time, which changed everything.
