Associating the articles to your property using the "Write an article for..."-link works, but you have to select the "None"-option from the dropdown menu. That way it associates the article to that property, and nothing else... I'm still checking out if something would work on the deleting the associated articles - so far no luck - so we might indeed need Aynara's magic for this... it might be that the only way would be that you'd have to ask a demi to delete your article.

PS: You can move the article from your property to a hood page, eg. from "None" to "Tula", but it doesn't work the other way round once you've associated the article to a real place. Bugs galore...
