As others have mentioned, there are other factors included in buying a home.
Other than credit score, you need to factor in your residual income. This is the money you have left over after all of your monthly payments.
For a home that you want to buy, there is a certain minimum residual income level that you need. This number is calculated based on all of your monthly payments, your house payment (principle, interest, taxes, insurance, mortgage insurance) and square footage of the home.
A good lender will work with you to develop a strategy to get to where you need to be to purchase the home you're looking for.
