Why Do 2nd Lenders Make The Short Sales Process SO Hard?

O.K. So we all know the short sale process is really fun to start with, but what are 2nd lenders thinking?? We represent many sellers in the short sale process and we all know several will have 2nd mortgages. We are working a file now that has a 2nd and the wonderful bank wants 20% of the balance owed to settle and give approval for the short sale. After going back and forth with them for many weeks and trying to counter, they just come back with the... Sorry, it's 20% ( cash only, no payments) or nothing. O.K. so you want 20% or nothing, the first will give you $3,000, but if you only want 20% or nothing, I guess you will get NOTHING !! The home will be taken back by the 1st, the wonderful 2nd lender will be wiped out and they will get their wish of NOTHING. What on earth are they thinking? Good luck with the hard ball play, it just won't work in the long run.
