Mortgage advice needed

We owe $190K on a home in San Bernardino that is worth less than $119K. Should we just turn it in for a deed in lieu? The payments are about $1900K a month and we could only rent it out for about $1500. Do you think WAMU will accept less than what we owe rather than a deed in lieu??? Has anyone had any luck with WAMU or can suggest a good lawyer to help us negotiate the principle down or anything like that???

Anyone have any luck negotiating the principle of the loan down??? Thanks!!!
