The article wasn't very clear, but I went to Fannie's site and read the details. The biggest change is that income from non-borrowers can be counted. The DTI max goes up to 50%, up from 43% DTI with 680 Fico. Definitely not sub prime, but the DTI is quite high. Most renters in high cost areas pay about 50% of their income in rent anyway though. It will be interesting to see how this plays out, will non-borrower income be fudged? Maybe who knows, but it looks like it will help more borrowers qualify that ordinarily wouldn't.
