I have a 984 Vantage right now. The negatives that are holding me back on my FICO scores are late payments. I have about seven accounts that went late for a period of 6 months in 2008. The lates range up as high as 150 days. My Vantage score was around 850 until recently when it shot up to 984. That was right around the time my late payments aged past 4 years. Hard to say if that was the reason, but maybe Vantage virtually ingores late payments once they age past 4 years.
Starting Score: ~500 (12/01/2008)
