We can help housewife's get car finance but this is a tricky situation if i'm honest. If you had good credit it wouldn't be an issue but, as you say you have poor credit the lenders we use will look for proof of income - as you have none they wouldn't approve you on your own unfortunately.
The only chance to get approved is to make a joint application with your husband as the main applicant as he's the one earning a wage.
Please make an application and once approved you can choose a car from any dealer and we also provide a no obligation quote. Kind Regards, Rachel
