Congress has inserted a special provision in the Bankruptcy Code that prevents reducing the amount due on the first mortgage on your home. Bitter battles have been fought in congress on this issue where debtors have lost.
Redemption and reaffirmation are complex options which have many traps for the unwary. Unfortunately your question shows that most non lawyers including you do not have the knowledge to avoid them
There may be options to save your home such as loan modification which you should explore. You need to consult with an attorney who knows loan modification and bankruptcy.
There is way too much information required to give any good advice about this issue in a forum like this.
You REALLY need to meet with a competent local attorney familiar with bankruptcy and loan modification.
You may need to convert your Chapter 7 to a Chapter 13 to save your house, but time is limited. You need to talk to that attorney SOON!

You did not mention whether you have an attorney helping with your case. If so, you should discuss the options ASAP. If you don't, you should find one to explain your options. Redemption, reaffirmation and the other options available are each distinct, separate legal remedies with consequences for both your bankruptcy and your finances after bankruptcy. Best of luck.

Bankruptcy law is a very complex and is beyond the clear understanding of most individuals as well as attorneys who do not practice in that area. Your questions will be best answered either by your attorney, if you have one, or by consulting with an experienced bankruptcy attorney. There are many options, including converting to a Chapter 13 bankruptcy, that need to be considered when trying to maximize the benefit of discharging debts and retaining ones home.
