My point was more about how journalists too often spout "PRICES DOUBLED!" to get attention like blood in the water, including here. And, in too many cases, it's over a time period that's 10+ years, so it's not really doubling, but 6%/year.
And, yes, leverage can profit, but it can bite hard too. Plenty of people bought at $500k with $100k down, then saw the value drop to $300k, meaning they lost 200+100 = $300k if they had to sell.
All fun math, with, yes, GROSS simplifications here.
