What is expected to get a auto loan from Nissan/Honda dealer?

I'm a stay at home mom but I can get a part time job if I also need proof of income. I have 7k savings and was wanting to make payments on a new car. I own a jeep right now and I own a mobile home. My monthly expenses are estimated at $400-500, lot rent is $125 utilities and sewage/water are 120-150 max, I'm able to coupon for food so we pay 50 a month to feed my family of 4. So literally my expenses are at 400-500 a month my spouse make 37k a year after taxes. We're married legally and file taxes together I haven't worked in the past year and a half but I know I have a credit score of 750 currently and went through 6 months of payments recently of 5k on appliance updates for my mobile home and just paid it off… I need advice on what to expect and how I can guarantee to get a car loan. My spouse has 2 credit cards 1 for 3+years and the second and the second one was a joint with me we took out in December 2014. But I know it will be difficult since he doesn't have a USA license or a social security number although I do have both

Your info looks good, but only a dealers F& I dept can tell you exactly what is required to obtain a loan with them + you would make more of a wise choice to purchase a used vehicle rather than brand new
