Is it rude to tell people in a social setting how much your mortgage payment is?

I’m in my mid 30s, living in a major city and everyone constantly talks about how much their rent is. I bought a decade ago and pay nothing for my mortgage compared to rents today because of the housing market. Should I just keep that to myself? I tell close friends and I know that’s fine, but would it be a turn off or considered bragging around less known people?
