the bigger the downpayment the more the bank will look to your 'skin in the game' and less to your credit.
They banks look at two critical factors
1) willingness to pay. The more the downpayment, the more you will be willing to pay each month in order to protect your equity. Does you past payment performance on other debts suggest you are willing to pay?
1) ability to pay. Can you income support the debt?
so if you have a poor credit history, but are putting more than 50% down (not kidding), then you would have a strong willingness to pay to protect the equity you invested in the home purchase. If you only put 5% down with a poor credit history, the equation is very different,
