Two more years of falling house prices? Could it be? Well, the chairman of Citigroup thinks so and he’s made that prediction in an interview Saturday with the BBC.

Win Bischoff, whose name certainly doesn’t match his bank’s performance, says he thinks prices will continue to go down, down, down–both in the U.S. and Britain–for another couple of years.

For the few of you left out there who are optimistic about the economy, this may actually sound like good news: two years more of lower and lower house prices…think of all the cheap homes that will be available to buy!

But there is a catch. Isn’t there always? You see, Bischoff also thinks the current credit crunch (which sounds like something you’d eat in a bowel with milk) will also keep on going right through 2009!

Translation: There may be tens of thousands of relatively cheap houses for sale, but not a lot of people around who’ll be able to obtain the credit to buy them.
