My (paid for) house in the Bay Area was built ~70 years ago, and it’s just fine, thanks :)

As a European living over here for the last two decades, I agree that European houses are generally sturdier (my parents house pre-dates the USA, I don’t expect mine to last that long), but when you’re spending 6 figures on something, looking after it is a good policy. Catching problems early is the key - as soon as you notice something, fix it and fix the cause…
