I have a few bad accounts on my credit report which will be deleted around 2008-2009. However we are looking to buy a house in the next year, and these do have a negitive effect on my credit score. I heard that if I dispute these items, they may be removed from my credit report. In fact I have disputed some items, and they have been removed. HOWEVER, I have disputed one item, and while it was paid off (thru collections) after the dispute the amount owed was put back on ($600). I needed to call the collection agency, and after a long conversation, it was put back to $0.
