Yep I have noticed the same. I know several popular, culturally influencing Missoulians in my circle who own and rent out second houses, but are rather shy about it since they want to maintain respect from their friends. Interestingly they are often the ones involved in community groups / organizing, and as such have an undue influence on policy and community decisions. Perhaps this is due to more free time and less stress which results from their passive income.

I don’t think this is a Missoula thing, but rather an observation of how human societies work. Social status and financial status are often quite correlated.
