First of all, let me say THANK YOU for serving.
I was in the Navy during Viet Nam, and NO ONE said that to me! It was an honor and a privilege, and I've never regretted it.
Now; please go in to your VA office and talk to them. They really want to help and they can guide you about a lot of things. Next, get a Realtor to help you, he won't cost you anything, they ar paid by the Seller, but you need your own representation.
Good luck and may God bless
