Lostinlife,
I got a similar mod from
CW a couple of weeks ago. Our interest rate stayed the same, my payment went from 764 to 855 (+$90). The only difference is that they told us we didn't need any money upfront. I am surprised that they required you to give them 5k. I actually told them that I had 4k upfront funds (I had been saving my payments), and they told me to keep it.
I wonder (if you decide to accept this mod), if they would waive the down payment for you...
We have accepted our modification because I have no more fight left in me....I have heard of a lot of members having great success, though, with NACA. Hang in there

Whatever you decide, it seems like a good time to be applying for modifications.
