> I bought my current home in 2011 for $420k, and the Zillow currently estimates its value at $757k.

Well yeah, in the last 20 to 30 years in most countries the story has been the same. My parents bought a house in Brazil in the early 90's for 30k and we're now selling it for 400k. My relatives in Australia bought a house in Adelaide for 400k around 5 years ago. Prices exploded there and it's now around 700k. They got 300k dollars in a few years while actually earning less than that in salaries over the same period.

On the other hand, me, in Europe, managed to lose money on a house I bought 10 years ago because I overpaid (at the time it was really hard to buy as competition was huge) and after COVID, prices in my region fell 20% and never recovered... Also, I invested too much on a new building in the property which people in this country don't actually value a lot, so the investment did not pay off.

But before that I had made 60k on an apartment in just 2 years. So, while I know too well that the housing market can be unpredictable, I would continue to bet on it going up in most markets since the conditions which made prices increase have not changed.

You also have to factor out inflation over those periods of time, as often it turns out the return is relatively anemic, but the time periods are long.
