Question for the financial wizards out there.
Scenario: My wife has zero debt, including credit cards. She has a cc (amex) that we pay off monthly, has been open for 10 years, unlimited credit. She has a spotless payment history, no hard inquiries, and a low number of open accounts. Somehow, her credit score is 720. I have a similar profile, but with 8k in student loan debt, and my score is 820. Is it that she has a lack of debt that is the problem?
Given her history/balances, shouldn't this be much higher? Is there something I can do to improve it? I don't even know what to do differently.
The reason I ask is because we are going to be applying for a mortgage in a few years. Is a 720 good enough to get the lowest rate possible? Should I even be worried about this at all?
Not trolling, realize this may seem like humble-bragging, but I want to optimize my situation.
