Fox Money, a personal finance hub, provides insights on credit scores and their impact on mortgage loans. Credit scores, primarily based on payment history, credit utilization, and credit history length, influence loan approval and interest rates. Minimum scores vary by loan type: FHA loans require a score of 500 with a 10% down payment, while conventional loans typically need at least 620. Improving credit scores can enhance loan approval chances and lower rates. Tips include correcting report errors, timely payments, and managing credit utilization.
