Depending on where you are in the foreclosure process, it may not be too late to contact your lender and try to work with them. Remember, lenders are in business to make money, not to own homes.

Unless you have already received a notice that your home is going to be auctioned, it's not too late to work with the lender. Consider contacting the HUD office in your local area, with all of the publicity recently about foreclosures (and the new Foreclosure hotline) you may still be able to save your home. There may be help available to you.

If the reason for the foreclosure is you simply cannot make your mortgage payments and you know that you're not in a position to keep the payments up after re-negotiations you should contact an attorney who specializes in foreclosures or a real estate attorney. If you do renegotiate, then chances are that there will be NO real warning on foreclosure after renegotiation because then you will be asked for 'deed in lieu of foreclosure' and that will mean that after whatever process is legally required by the laws in your state (see the links below) then the mortgage company can immediately auction your home.

None of the options are probably going to be free of charge so I'd recommend you contact friends and family members about enough of a loan to cover your legal (or other) fees.

Good luck.
