Dont get me wrong but new inquiry going to hurt your score.
- New account wont report after a few week . I dont know why the broker would suggest you do that but if you had someone can add you as an authorize user on their longest CC would be a best option. Nothing lose on this case and your score would be increase if they had long and steady with no late history.
Starting Score: 560
Credit Card company ussually report to credit bureau couple days after your statement cut. Some not report at all if you wont used your card like Credit One in my experience.
I heard some sub prime CC not report to credit bureau about AU but its YMMV. Hope its answer your question.
Thanks guys. It looks like I'm going to have to ask for an extension. I'm pretty sure I will get it. The home owner has said he would wait. With an extension what would be my best option. Will my score increase without a second card. If i use the one card correctly with a 9% utilization, I've read this seems to be the right #, and make my two i.stallment payments on time will that do it. I wouldn't have to worry about a hard pull. An AU isn't an option. 
The inquiry will cause a score drop. Also, some lenders dislike seeing new Apps before underwriting.
Is there anything else you can do that will improve the score? Utilization less than 9% has to be on statement date. Any old late payments where a goodwill adjustment might help?
Cap 1 isn't a company that would typically give a CLI, so that's out of the question.
You may inherit the 5 points next month with no effort at all between average account age slightly improving and the Cap 1 inquiry getting a tad bit older.
