There’s no minimum income requirement for a VA loan. However, you do need to have an acceptable debt-to-income ratio (“DTI”). This DTI takes your monthly debts and divides it by your gross monthly income.
Another income-related requirement relates to residual income. This is the amount of income that’s left each month after all other expenses have been paid. This remaining amount should cover food, transportation, and other basic living costs.
