Your credit score does not directly impact the loan amount in which you will qualify. The factors that determine your maximum loan amount/buying power is your debt to income ratio. Your document-able income, current debts (minimum monthly payments) as well as your down payment will determine the loan amount that you will qualify for. As for your credit score, in order to qualify for a loan you will likely need to have a credit score of 620 or higher. I say, "likely" because the required credit score is also based on your overall credit profile. We can offer a loan to a person with a 580 credit score if they meet a other requirements. It is also possible that a higher credit score will be required for some programs. However for most programs a 620 score will suffice.I hope this helps to answer your question.
