Yes, it can make things more difficult, but it doesn’t have to stop your plans. If you apply for a big loan together, like a mortgage, lenders will look at both credit scores. A low score from one partner can mean a higher interest rate or even a denial. The best move is to work on building both scores together. The partner with better credit might need to apply alone for some things at first, while the other focuses on paying down debt and making on-time payments to improve their score.

The rules are usually simpler than for a regular loan. You typically need to be a member of the credit union (which is easy to join), have a steady source of income, and be able to afford the monthly payments. They often don’t check your existing credit score heavily, because the whole point is to help you build it. The main thing they want to see is that you are reliable and can make those small payments each month.

You should ask them clear questions. Ask if they always pay the bill on time and in full. Ask what the credit limit is and how much of it they typically use. Most importantly, agree on clear rules about if you will actually use the card, what you can buy with it, and how you will pay them back for any charges you make.

The biggest risk is not having enough money in your bank account when the payment is taken out. This can cause the payment to fail and lead to fees from both your bank and the company you were trying to pay. To avoid this, always know when the money will come out. Treat it like any other important due date. Keep a cushion of extra money in your checking account as a safety net, and check your balance regularly.
