Hello P.,
I don't know if that website is valid or not, unfortunately I have to say that I probably is NOT. I am in the same situation that you are (SAHM trying to help out)
That being said, I just want to add to the comment that I have been working with my lender (Citi Mortage) for many, many months trying to get our loan modified and I feel sort of like a cat chasing her tail! one run around after another. They want you to let your loan go past due and even into forclosure before that will offer any help and after that it still can take up to 6 months. It's a tough gamble.
I really hope that you guys get the help that you need. I know that this is crazy, but I enrolled in Grad school so that I could use my tuition refunds as a supplemental income. (This is just how tough things have gotten...)
Best Wishes,
Christina
