How to request a COE

First ask your lender as they should have the ability to pull your COE.  Learn how to request a VA home loan Certificate of Eligibility (COE). This is the first step in getting a VA-backed home loan or Native American Direct Loan. It confirms for your lender that you qualify for the VA home loan benefit. Then, choose your loan type and learn about the rest of the loan application process.
