My most recent post is up on Angry Bear: Housing: Speculation and the Price-Rent Ratio
For a running list of News links on housing, see Patrick's Housing Crash site.
For an interesting graph and some great quotes, see Mish's "It's a Totally New Paradigm".
UPDATE: Another interesting article quoting Merrill Lynch chief economist David Rosenberg and Dean Baker, co-director of the Center for Economic & Policy Research: Bubble in housing will burst
Best to all.
