Hello Baltimore Seller,
Like Chad answered, There will be quite a few things to consider:
1. How much you will have left over from the sale of your home to put down on the new one.
2. What monthly mortgage you will qualify for
The latter question will be answered by both your husband credit scores and yours. Chad laid it out nicely. You will either be paying higher interest rate including your credit information or . . .
You will be paying a lower interest rate, but a smaller loan amount using just your husband's credit.
Are you going FHA? Are you getting outside help with closing?
I have an agent who's customer had to go through an angel investor because he was self employed and his tax records showed less income then he actually had due to deductions. He didn't even qualify for a loan even though he could more than afford the home.
Banks DO take into consideration your income when determining how much you qualify for. However they put more weight on your debt to income ratio.
I would get a pre-qualification before you do anything . . . get one with and without your income/credit score included and go from there. Once you have that, you are armed and you can shop around.
