A paper by Brent T. White University of Arizona - James E. Rogers College of Law pretty much explains why.
Underwater and Not Walking Away: Shame, Fear and the Social Management of the Housing Crisis
pg 39 - 42
"...Recent studies seeking to explain this apparently irrational behavior have shown that lenders are simply operating to maximize profit and minimize losses, just as they would be expected to do. First, lenders know that borrowers with high credit scores are unlikely to default even at high levels of negative equity. To modify loans for these homeowners would be to throw money away – and to encourage more homeowners to ask for modifications. Second, a significant number of homeowners who temporarily default on their mortgages “self-cure” without any help from their lender – though self cure rates have dropped precipitously in the last two years.
Again, to modify the loans of individuals who would otherwise self cure would be to throw away money. Third, homeowners with poor credit, or who end up in arrears because of “triggering events,” such as unemployment, divorce, or other financially devastating circumstances are likely to default on the modified loan as well. To modify loans for these individuals is to waste time and risk housing prices falling further before the lender eventually has to foreclosure and sell the property anyway."
Given these economic incentives for the lender, a seriously underwater homeowner with good credit and solid mortgage payment history who responsibly calls his lender to work out a loan modification is likely to be told by his lender that it will not discuss a loan modification until the homeowner is 30 days or more delinquent on his mortgage payment.
The lender is making a bet (and a good one) that the homeowner values his credit score too much to miss a payment and will just give up the idea of a loan modification. However, if the homeowner does what the lender suggests, misses a payment, and calls back to discuss a loan modification in 30 days, the homeowner is likely to be told to call back when he is 90 days delinquent.
In the meantime, the lender will send the borrower a series of stronglyworded notices reminding him of his moral obligation to pay and threatening legal action, including foreclosure and a deficiency judgment, if the homeowner does not bring his mortgage payments current. The lender is again making a bet (and again a good one) that the homeowner will be shamed or frightened into paying their mortgage. If the homeowner calls the lender’s bluff and calls back when he is 90 days delinquent, there is a good possibility that he will be told that his credit score is now so low that he does not qualify for a loan modification.
The homeowner must then decide whether to bring the loan current or face foreclosure. If the homeowner somehow makes clear to the lender that he has chosen foreclosure, the lender may finally be willing to negotiate a loan modification, a short-sale or a deed-in-lieu of foreclosure – all of which still leave the homeowner’s credit in tatters (at least temporary)."
