Being a transient city, there's always people coming and going, regardless of how the economy goes. The prices may rise or fall to suit the economy, but by and large it's not going anywhere. There is a lot of new development, and a lot of new condo projects hitting the market, which may skew the vacancy numbers a bit. But while it may (and has) slowed a bit, I don't see it crashing. I've worked in real estate title for almost 15 years, mainly in DC, and even when the bottom fell out, DC wasn't affected nearly as badly as the surrounding metro areas
