It must be very rewarding for you to have achieved 82 properties and for that you should commend yourself. Although your way worked for you, I wouldn't recommend it for anyone who would ask me. Risk is a calculation that affects the outcome of cash flow, debt and the decision on what to invest in. Some investors are willing to take a large risk and levarage their way into multiple properties. Statistically, for most people it will ruin them financially. All it takes is a market down turn, rental decrease, more vacanies due to the economy, a death in the family, a job loss, income loss. All of these factors can ruin one's financial world.
Although Mike's cash flow is currently at $300 a month, he still has a very high mortgage payment and not a ton of equity which can take a 30% to 40% dive like it did in the housing crash of 2008 and 2009. That dive also hurt rental rates, because people couldn't afford the high costs of renting, which at that time hurt property owners cash flow, which in result led to difficulty in paying ones mortgage. In turn those who needed out of the rental, couldn't sell without bringing money to the table.
So, yes just using mathematics without calculating for risk, this deal looks to good to be true and as a result, it is most of the time. So on that note, I don't recommend leveraging beyond your means and putting more of your money into each deal and to allow the extra cash flow to pay down the mortgage and to gain equity. To me, it's more about not taking such high risks and it's more about being able to withstand any horrible disaster that took place in 2008 and 2009, that bankrupted so many people.
As they say, risk=rewards, well risk also ='s great losses.
