2 junior liens up for trustee's sale

[Blaine Shannon]

I'm tracking a home that has 2 juniors liens going up for trustee's sale, the senior loan is huge...almost 1 mil. If nobody bids on the junior liens, they (the lender of the junior liens)own title to the home right? Do they begin forclosure? and is senior loan wiped out? Can I contact the lender to the junior loan and make an offer lower than the senior loan
