What to do with old tenant's stuff

[shumashi.livejournal.com]

I've been living in my current household for a year now, and the previous tenant still has a large amount of belongings here, which he claims to still want. About two rooms full. It's a bit excessive.

My housemate/landlord and I are resigned to have to deal with it ourselves. We'll do the polite "Here is your final deadline" thing with the old tenant, but I'm not entirely sure what we should do when he doesn't come to get it, which he almost certainly won't. I am looking for ways for it to go away at a minimum of fuss and expense to us.

It is fairly low quality stuff—neither of us wants any of it—but a charity might make use of some of it. Are there organizations that would come and cart it away to a good home? Or should I be looking into junkmen? (Does modern society have junkmen? It sounds so Charles Dickens.) My more-benevolent-in-this-particular-matter landlord was thinking of renting storage, moving it all there, paying for the first month in cash, handing the old tenant the key and declaring the matter resolved, but that seems both time-consuming and expensive to me, not to mention I'm not convinced you can rent storage and pass it over to someone else without their cooperation.

Advice and recommendations would be most helpful.
