COVER LETTER TO 2ND LIENDHOLDER

How would you tell the 2nd lien that you are offering minimum to them and you need for them to reliese the lien?
would you say something like:
Here is a shortsale for the subject property. You are the lienholder and we just received a modest offer to purchase it. Due to many costs, we are offering 10k to release the lien.
need ideas. thanks.
