He is recently divorced, taking care of his kid and filed for BK earlier this year and has been discharged.

Why wouldn't you offer the vendor the price of the property minus your repair estimate (+ buffer) and leave it up to her/him to discharge their HELoC out of proceeds just as they would a remaining mortgage note?

They would only do that IF the borrower filed a chapter 13, filed a motion to lien strip a junior lien, was successful in that motion, and completed the chapter 13 and got their discharge and THEN notified the lender to reconvey the title back to them.

Credit score is 699 but no conventional loan people would look at me until the ch.7 discharge is 4 years old My question is can she turn over the mortgage to me ?

Tax deeds convey title to the purchaser free of all prior encumbrances (i.e. mortgage liens, judgment creditors, etc) EXCEPT liens specified by Revenue and Taxation Code Section 3712, Lis Pendens actions and any IRS liens that are not discharged by the sale. 

Hey @Neel Shah the cause of loss with either fall under accidental discharge or overflow of water or freezing pipe.

You may already know this, but due to your medical discharge, the required funding fee for a VA loan could be waived.  

He had only liability insurance and was on disability.  6 surgeries and 14 months learning how to walk again left me filing for bankruptcy. 2009 march, bankruptcy discharged.

I think you need a discharge that was not dishorable, not sure.

Other than the IRS and weed abatement liens, are there any other liabilities that do NOT get discharged from the property bought at the Auction?
