Empty pub

I walk past this pub twice a day. It used to be called the Princess Victoria but was renamed some time last year. Since then it went steadily downhill (at least from the outside - I've never been in it) and appeared to be open at random times. It now appears to have been shut for a couple of months or so and it's beginning to drift into dereliction (a couple of windows have been broken).

The reason I mention this is that it's got me to thinking how one might find out if a pub is on the market, and how much it's going for. When I first started looking into this "running a pub" idea, I just looked in Dalton's Weekly. I assume there must be specialist estate agents or the like for pubs - wonder if this pub is in one?

Not that I'm all that interested in this particular pub. Although it's location is pretty good there are several other pubs nearby so competition would be pretty fierce (which is maybe why it struggled before). Anyone got any ideas as to how I might find out whether it's up for sale (and how I might find other available pubs also)?
