Ask Money Girl: What Does "Insufficient Credit History" Mean?
Q. My new apartment asked for a deposit due to my "insufficient credit history." I do have some negative items lingering on my credit report, but I don’t currently owe anyone anything. What more can I do?
A. Having an insufficient credit history simply means that your credit file wasn’t old enough to satisfy the apartment. The best way to build a history of positive transactions is to use a credit card responsibly by making charges that you pay off in full and on time every month.
