In the Zurich Greater Area, you can get this for example: https://www.immoscout24.ch/buy/4002631314. Keep in mind that in most of Europe, real estate ads show the living space, i.e. surface net of walls, corridors, closets, cupboards, etc... whereas in US/Canada it's the gross surface. Those 350sqm are prolly 280 "livable". So if you're willing to live outside the Zurich city core, prices are comparable to Seattle but construction quality is way higher.

Also, most mortgages in Switzerland are very peculiar: you pay 20% down, but then you don't ever pay off the principal, only interest on the remaining 80% which is owned in perpetuity by the bank. The interest rates are kept very low and the currency quite stable, because most of the citizens rely on it. So your monthly interest could be 400-500 CHF, and you invest the rest however you prefer.
