Legal Question in Real Estate Law in California

Re: California Anti deficiency law

As I understand Code of Civil Procedure section 580b, it would bar a deficiency judgment on any loan used for purchase money, whether it is a first or a second, if the building in question is a one-to-four family structure and you occupied at least part of it as your principal residence. You might be liable for a deficiency if there were any "cash out" or loan-application fraud. I believe this is true whether it was the same lender on both portions of the financing or not. I am a bit hesitant to say I'm 100% sure without having the opportunity to read the documents in question.
