Yes, as the other agents below have already stated you can used your VA loan while still having one active on another home. The max loan amount with both homes must be under 417K but you can do a second loan if you need to cover expenses past the 417K and that is called a VA jumbo.
As the wife of a retired Soldier and Realtor I have done tons of VA loans. I have a special rebate for our Military Honor program that also might help you in the home purchase.
