It really depends on your lender. I do loan modifications with an attorney. Our office is in San Jose, Ca.
You really need to be on top of the process. I have stopped a few foreclosures within days of the sale date by getting in all of the required documents.
You have to get everything in writing. Usually, if you have all of your info in and your with a negotiatior they will not foreclose while your trying to work out a modification.
It is not a guarantee, you really should have a plan and know how your going to proceed.
I am happy to answer questions and maybe give tips to make sure your on the right direction..
