Product: Mortgage

We built our house in XX/XX/XXXX. XXXX sq. feet finished, XXXX sq. feet unfinished basement, XXXX car garage on a XXXX acres. The mortgage was XXXX XXXX and XXXX XXXX. We wanted to finish the basement and the home appraised for XXXX when completed. We took out enough to finish the basement and purchase a rental property ( down payment ). We borrowed XXXX total by XX/XX/XXXX. We were thinking that we were good with XXXX still in equity. Our builder went out out of business by XX/XX/XXXX and left XXXX vacant lots in our subdivision. A new builder came in around XX/XX/XXXX building homes that were listed in the XXXX 's and we owed XXXX. I had an appraisal done XXXX XXXX that came back at XXXX. This absolutely baffled me as we have XXXX sq. feet and the new homes were XXXX-XXXX with no basements. The appraiser said they had to use the comps from MY neighborhood since there were XXXX homes sold in the last 6 months. There are no homes on the comparisons like our home whereas when they originally appraised it in XX/XX/XXXX, they used outside homes. ( All B of A ) The XXXX is now at prime +0 and the XXXX is a standard 30 year mortgage ( XXXX are with Bank of America ). By XX/XX/XXXX We started trying to fix the rate on the XXXX predicting that rates were going to increase and wanted the security of knowing our payment not fluctuating on the market or the upcoming elections. B of A stated that they could n't because the value was n't there. My mortgage was n't backed by XXXX or XXXX so HARP could n't help. I am not a veteran so that was no good. I did n't lose my job or have " loss '' of income so that could n't help. I called them for about 4 years trying to lock in a rate while my months to repay the now XXXX XXXX kept shrinking as it has to be repaid with a max of 15 years. ( my XXXX mortgage is now less than this HELOC ) XXXX HELOC and XXXX on the XXXX ) When discussing this situation, they said the only way would be a modification to the HELOC which would negatively impact our credit. I have no idea why the bank that has both mortgages would want to negatively impact our credit. I am not moving, I just want a logical fixed payment on the XXXX where if I wait until next XXXX XXXX that payment would go from XXXX per month to XXXX per month. Meanwhile, my XXXX is at XXXX and we have 19 years left on it with a monthly payment of XXXX. I am trying to do the right thing by pro-actively searching for solutions for the last 4 years and Bank of America seems to have no options. I know that we can not afford a XXXX mortgage payment and do n't want to lose our home. 
We both have student loans which does n't help our monthly budget but we are paying them down. As of XX/XX/XXXX, we have no unsecured debt, just the XXXX mortgages here and XXXX with the XXXX. We have XXXX car payments. I do n't want to walk away from our home as our XXXX children have grown here and we love the neighborhood. I do n't want to threaten the bank, however it seems as though they are pushing us in a corner. We do n't want to hurt our credit as we both have worked all of our lives to build it and ethically and morally I believe in always paying your debts. Please help.
