When you buy a house, all your info is public information on your county's website (most up to date counties). Unfortunately, I don't think you can stop them from publishing that information and having bots scrape that data to send you junk mail.
That's not true of “large, secured loans” in general.
OTOH, it is true of certain real property interests, including those of both owners and secured lenders; this is about the size of a secured loan, it's about clarity of title to real estate.
My understanding is that if it can be repossessed, the lender must have recorded the debt.
It applies to assets other than real estate, too.
And the credit agencies will sell your info to anyone.
In what state? Dallas County (TX) and Broward County (FL) don't. Nor does New Jersey (we have a unified system for all 22 counties). In Dallas County I can even see the names of everyone who owned a property for the previous five years as well.
