Sorry if this seems a little long, I just wanted to give some history to help.
I have been doing a ton of research since I found this site. I have already increased my positive TL's from a single Orchard Card 300 CL to the following.
Sea Miles 1750
Credit One 600
Kay Jewelers 1650
My ultimate goal is to be in the position to purchase a house in about 2 years. At the time I hope to have raised my score signifigantlly as well as save a large down payment. I am also in the process of trying to clean up some baddies. I have had the Hooters, Sea Miles and credit one TL's for a coulpe months. I have used all of them and kept the Util at reporting time under 10%.
I have read in a few places that if you can get a secured card with one of the prime lenders and after 9 -12 months they will convert it to an unsecured account. My idea is to wait till about this time next year, when I will have had my current TL's for about a year. Apply for a secured card with BOA. If I put down $10,000. Will that amount later be converted to unsecured? If I have a large CL like that, will other prime lenders be willing to give me large CL's? Lastly, do secured accounts figure into your score any differently?
Thanks for all the help. I have already made big improvements, I just want to get up to prime market in 2 years, even with some baddies I can't remove.
This is an excellent question, but unfortunately, I don't really know myself (although I have thought about doing the exact thing you mentioned with $10,000 this past week in an effort to get that high CL, which hopefully would in turn significantly raise my FICO scores)...
