If you don’t have very good credit, financing your home may not be easy. If possible, apply for an FHA loan; these loans are backed by the United States government. Even when the resources for making down payments or paying closing costs are lacking, FHA loans can help.
If your credit card has a balance of over 50% of your limit, it should be your number one priority to pay it off until the balance is under 50%. Your credit score can diminish with balances over 50%, so spread out the debt or pay off the credit cards.
