Thank you for your service.
Your score is good enough to get your foot in the door so to speak. The rest of the process will depend on your actual credit history, debt to income ratios, disposable income ( only an issue on VA loans) & the competency of your loan officer/lender.
The real question I have from your post is about your income. Your GI Bill can not be counted as income for qualifying so you would need to have another acceptable source like VA or SS disability, a job or retirement/pension.
