I'm not familiar with using NPV for a loan mod. I've found that the borrower must have at least a 35% DTI (debt to income) ratio in order to qualify. So, you may have to fudge your utility bills to come down or go up to get to that number. If you're too low percentage wise, they may turn you down because you don't need it. If it's too high, it's because you can't afford anything. Other factors include but are not limited to: Loan to Value, area of property and foreclosures in area, lender (wells fargo doesn't foreclose for up to 12 months), mortgage history in the past, and how often you call them to update on your situation. Those who don't call, don't get as much attention.
