I've been reading more of this forum post as creative financing and no down-payments interest me. One, I have no money for a down payment! Two, for those who have money, I tend to think of deals with down-payments and turn-key rentals as "low hanging fruit." If you have the ability, you can walk in to a bank and get a conventional mortgage easily and start cash-flowing immediately. The really good deals take time and effort as @Ben Leybovich points out, as he only has done one deal a year.
So it is a matter of how quickly and immediately do you want a deal? They are easy to get with money down. But if you wait and look and be patient, you can get truly amazing deals with no money down, utilizing OPM, having a smaller share in more properties than a huge share in just one. I go back to McElroy's book, I would rather have 10% equity in multiple big properties than 100% in one property where everything is on the line. I think multi-family units and apartments could be the way to go for me, if I put the effort and time in to studying cash flow operations and creating opportunities. I will have to study more on this, but it seems this strategy could be really promising for me. But also, each person has different situations and circumstances. So it seems finding the right strategy for the person is key. Like @Ali Boone says, find what you enjoy doing and do that. Don't force yourself to do something that you are not designed and have no desire to do.
