Ignorant Steve,
Renting there may be a luxury, but personally while I'm saving for a deposit I'm not going to live in a dingy bedsit.
I can pay only £600 in rent for what would cost me £950 on an IO mortgage.
Why not splash out? If you can still save then you can live wherever the feck you like.
My current landlord is in trouble too.
2 weeks till I move out:

He has had 1 viewing and no offers (not even a cheeky one).

He has had 1 viewing to re-let it, and they didn't seem interested.
He admits that even if he gets £30 a month more than we're paying now (thats what its being advertised for - won't get it IMHO) that it won't even cover the IO mortgage that he has, and thats with a 20% deposit.
And it has been valued by the EA at about the same price he purchased for 2 years ago, so he is likely looking at losing some of his deposit even if he does manage to sell.
I can imagine a few landlords I've known being in similar positions...
