Modification problems

i have been trying to modify my home mortgage for 5 months with no success. i lost my job and took on a new part-time job at 1/3 the former salary. in the meantime, i have used up all of my savings keeping my mortgage current--but the servicer keeps saying i have too much income despite the documentation i provided to them. (this is mostly because 5 times i have applied for modification--both through hamp and through the lender's in-house mod program) but every time the nameless paper pushers make errors and then refuse to change the errors (like writing down double my current income or verifying my previous income!). however, i have a credit rating of about 780 and will soon return to my former professional salary as the employer has said they will be putting me back to full-time very soon. i would like to stay in this house as a single mother with two children in school and i have put alot of money into this house to remodel and upgrade, as well as buy down the prinicipal. i cannot sell the house or refinance because the value is less than half of the mortgage outstanding--plus the servicer won't speak to me about that anyway because they insist i have adequate current income. my question is, is there somebody that would buy my mortgage at the current amount from this servicing company and let me pay them the money and the interest? i am obviously good for the money. the mortgage payoff is $167k and the current taxable value is $87k--but zillow says $105k.
