The Federal Trade Commission does not have good things to say about so-called "forensic loan audits" or "forensic mortgage loan audits." According to them, they are "a scam to exploit financially strapped homeowners." Read what they have to say about them at http://www.consumer.ftc.gov/articles/0130-forensic-loan-audits. In my experience, forensic loan audits are just another way for you to be victimized. The people that sell them typically charge you hundreds or thousands of dollars, for no benefit to you.
If you feel there is a problem with your mortgage loan, whether the problem relates to the origination of your loan, the servicing, or anything else, hire an experienced consumer law lawyer. He or she can either analyze the loan for you, or hire real, competent experts to help them analyze it to see if there are legal violations that may possibly benefit you.
My advice: don't waste your money on charlatans that are out to cheat you, no matter how fancy their website is, or how competent or knowledgeable they sound on the phone. No, you can't believe everything that is written on the internet.
If you are facing foreclosure, and you want to keep the property but your mortgage servicer will not agree to any kind of workout or loan modification, consider filing Chapter 13 bankruptcy to stop the foreclosure and allow you to catch up the loan over a period of time.
