I'm attempting to use the VA loan. I have been pre qualified, have my certificate of eligibility and have a house under contract. I am now going through the formal approval process and my lender told me today since I only have 7 months left on my enlistment that the VA requires that I get a letter from my commander saying that I can reenlist and a letter from me saying that I plan to reenlist.

Is this actually a VA requirement or is this a lender requirement? It shouldn't be a big deal to get the letter but I was upset that my lender didn't tell me this sooner.

It's a standard requirement. Active duty personnel have to show they will be continuing on active duty for at least 3 years from the closing date.
