Acting fast and honest is the best way to fix credit and probably the most efficient. You need to build a healthy relationship with your creditor, because his interest is to get the money back from you, even if it takes more time than initially evaluated. If you talk to the creditor on a regular basis and explain your financial problems you will certainly be able to receive an extension and smaller payments that you can actually afford.
Since the start of the crisis many people have found themselves in the impossibility of paying their credits. To fix credit these days could mean selling property, but you do not need to do that, especially if you still have a steady and consistent income. Now, even though income is not as large as it used to be, you can talk to the people that you owe money and, as I mentioned earlier, ask for an extension. This is something that people do these days more often than any other period, so it is nothing special. You just need to realize that there is a problem and to talk to the creditors.
There could also be problems with the information in one or more of your credits. This is a problem that can be solved easily, without any kind of stress. You can ask for a credit report and identify the incorrect information. After that is done you just need to send a letter with the correct information to the credit or go yourself if you have the time.
When it comes to fix credit for a large company there could be an additional problem that occurs often. It is not the difficulty of the fix credit process, but the amount of information that needs to be processed. This is why most companies have an entire department working with this type of situations. If your company does not have such a department you can employ a fix credit company that can do the work for you. Be careful when choosing the company and get informed about their former experience before hiring them. It is your money you are playing with, so caution is advised. You can also be part of the team that works on the problem and manage things yourself, but put the burden on the employees of the fix credit company. You will need to do this probably because they handle all your money, literally.
