NEW YORK ( TheStreet) -- The five largest mortgage servicers have provided more than $45 billion in gross relief to nearly 550,000 consumers as part of a nationwide settlement over foreclosure violations, settlement monitor Joseph Smith said Thursday. Still, banks' efforts to provide relief might not be enough to satisfy demands that more needs to be done for borrowers. Consumer advocates and critics of the settlement would point to the fact that the bulk of the relief came in the form of short sales and forgiveness of second-home loans, which do little to keep borrowers in their homes. And a recent settlement that abruptly put an end to independent foreclosure reviews promised to borrowers in an earlier enforcement action has raised concerns in Washington and increased calls for more justice related to the foreclosure abuses. As a quick background, Bank of America ( BAC), JPMorgan Chase ( JPM), Citigroup ( C), Wells Fargo ( WFC) and Ally Financial entered into a $26 billion settlement last March with 49 states over alleged foreclosure violations known as "robo-signing." The settlement required banks to provide at least $20 billion in relief to consumers through a combination of principal forgiveness, loan modifications, refinancing and offer delinquent borrowers alternatives to foreclosure such as short sales and deeds-in-lieu of foreclosure. Banks only get partial credit for every dollar of relief extended, so the $45 billion provided so far meets only a part of that obligation. However, the monitor recently said Ally Financial has completed its obligation under the settlement. "I believe we have made progress, particularly as it relates to consumer relief, but I know from my regular conversations with advocates across the nation that the banks and I have much more work to do on behalf of borrowers," Smith said in a statement. According to the latest report from the settlement monitor, banks conducted short sales totaling $19.5 billion between March 1 and Dec. 31, 2012. In a short sale, the bank agrees to let the borrower sell the property for an amount less than what is owed on the mortgage. The proceeds are used to settle the debt and the remaining mortgage is forgiven.
