One other key difference that makes leverage in stocks scarier: once you hit zero, you’re wiped out. In your example, a 20% decline in stocks would wipe you out. In principle, the same thing can happen to a home. But there are two reasons it isn’t as bad : 1) as long as you keep up the payments, the lender won’t foreclose you. 2) there’s a dampening effect in home sales - when demand softens, volume collapses. So a 20% decline doesn’t happen as often. I owned a house in Redwood City during the 2008 collapse and ended up under-water in it for a while (negative equity). I just held on and it recovered nicely, and I sold it for a great profit in 2014. My stock broker would’ve never let me do that. More broadly, buying is also an “option” to stay in the area long term. In a place like the SF Bay Area, where you just can’t tell what will happen next to house prices, that should be factored in as part of the value.
