hi guys, I have a serious question here. I buy my house 10 years ago with a mortgage loan of 150k. due to a lot of late payment and interest charge, after 10 years I still own the bank 179 k now. During the 10 years I already pay like 100k of interest. I am planning to sell my house now. Question is is there anyway I can ask the bank to lower the balance I own them? Or any sifu  here can teach me what to do? Thanks.
