Can I get my home back after the Foreclosure Sale?

Here is our situation, We both lost our jobs, house went into foreclosure, bank know owns the house and they transferred it over to the REO department (Realestate Owned). We are still in the house trying to figure out a way to get our house back. We don't have much money due to our situation because I recently got a regular income/benefits job. My credit score is right around the 500 mark. I've contact the REO to get a purchase price for our house but the bank doesn not have one so since the current principal balance is 283,721 I offered them less (instructed by another company to put something on the table to see what they come back with) I am awaiting a response from the REO or real estate agent that is currently working with the bank. To date we still live in the home and have not received an eviction notice. CAN YOU HELP US. Can you also tell me the name of your company since there are so many scams out there and there are so many people like me in the same situation. Do you think that you might be able to help us buy our home back. We recently received a letter of 30 day notice from the bank's attorney and if we don't leave the court eviction process will start. I currently reside in Brockton Massachusetts and my lender is Ocwen. Due to our circumstances we are both working but we want to keep our home. To date we have not received an eviction notice but we are trying to research every possible avenue to try and keep our home. If you can help us or can refer us to an agency within our state I welcome any advise you can give us.
