Well, I was just speaking of my own experience with real estate. Here is a tidbit of data:

In King County, Washington, since 2012, real estate returns had average annual price increases of 8%

Anybody could have borrowed at 4% or lower during that time period. Real estate allows you to borrow at very low rates with no danger of a margin call. So you can borrow $1,000,000 zero down or for 200,000 if you want to avoid PMI and you are effectively making 4% on 800k of not your own money risk free while you wait for property values to go up then take your capital gain tax free up to 500k...

Oh yeah, and I forgot to add you get to live in that place rent free...
