US property market is about to crash?

An article claims, that the property market in the United States will collapse any moment, since many home owners cannot make necessary mortgage payments.

Another one also discusses a problem with payments - this time describing a particular controversial mortgage product, still quite popular in the US, which the article claims was wrongly sold to many people who didn’t understand the risks involved.

I must admit that both articles were linked from Calculated risk - probably the biggest property crash whiners on the Internet.
