How much mortgage debt is nearby within the USA?

Given all the worries about credit surrounded by this country, and subprime mortgages, I was curious as to what the entire amount of home mortgage debt is. There are about 110 million households within the country, with 70% of them owned residences. Let's say in attendance are 75 million owned homes. Not all have mortgages, but if 70 million do, and the average mortgage amount on such homes is $200,000, that comes out to a terrifying $14 TRILLION of mortgage debt in the USA. If just 2% defaulting, the amount of bad home loans is $280 billion. It could obviously be much better.

Does anyone know what total mortgage debt is per household and in total? This is a real problem that could destruction the economy.

I don't know the numbers, but it is an astronomical amount.
