When i paid off my house and calculated my total payments, it came out to 6.8 years of the rent we had been paying when we bought it, (which was of course going up annually so it's probably better than 6x)
100x was a bit extreme for the sake of a simple example, but rental yields in eg Singapore are around 2-4% apparently. And they don't have capital gains tax. So investing in stocks or bonds and using the returns to pay rent really does look more realistic in that part of the world.
100x is just bad decision making
