Which document must a veteran obtain to verify eligibility for a VA-guaranteed home loan?

Correct answer: Certificate of Eligibility (COE)

A Certificate of Eligibility (COE) is the official document issued by the Department of Veterans Affairs that confirms a veteran's entitlement to VA loan benefits. While a DD Form 214 (discharge document) may be submitted to obtain a COE, the COE itself is what lenders require to process a VA-guaranteed loan. A Statement of Service is used for active-duty members when applying for a COE, but it is not the eligibility document itself.
