If the US defaults on its debt the housing market will be the least of your concerns. It's difficult to predict exactly what would happen, but a total global economic collapse would be in the right ballpark.

That said, nothing is going to happen. The "debt ceiling" is political theater and the idiots in Congress do this every year.
