To qualify for a mortgage, lenders evaluate creditworthiness, focusing on credit score, stable income, low debt-to-income ratio, and clean payment history. Mortgages are long-term loans secured by property, with varying terms and interest types. Credit scores range from 300-850, influencing loan access. FHA loans require a minimum 580 score for a 3.5% down payment, while VA loans have no strict minimum but often prefer 580-660. Credit repair services can help improve scores for better mortgage options.
