Some common reasons for a home loan denial include low credit score, high debt-to-income ratio, insufficient income, and a history of late payments or delinquencies. Other factors may include a low appraisal value, insufficient collateral, or a lack of down payment. It's important to work on improving your credit score and financial standing before applying for a home loan, and to shop around for lenders who may be more willing to work with individuals with bad credit.
