Once you have verified with your lender the information that they require, gathered the necessary documents, and submitted your information, the negotiation phase begins.
Patience is a virtue when it comes to negotiating with lenders. It can take from two days to several months to work out an agreement. Lenders today are swamped with loan modification requests.
Although who your lender is makes a great deal of difference, if you are dealing with a large organization be prepared to submit your package more than once, wait on hold for long periods of time, and wait even longer for your calls to be returned.
The important thing to remember is not to let anxiousness overcome your ability to negotiate favorably. If you cannot do this hiring a professional may be your best bet.
