Eric,
It’s best to write the “actual” reason for the hardship that caused the default. Pull at the heart strings as much as you can.
Keep in mind that with most short sales the BEST you can get is a 20% discount off the appraised value or mortgage balance ( which ever is greater). The lender will give an additional discount for STRUCTURAL defects only. Plus, an assignment of contract or simultaneous close will not be possible so plan to provide a proof of funds along with your short sale package and be prepared to buy/close if your short sale is approved.
