First, go to the VA website and click on the appropriate link. You should find, among other things, a list of VA approved lenders in your area. Then, contact a couple of them and see what is available.
VA interest rates change periodically, but this is also published on the website. There are programs which help you buy with no money down, which require sellers to help with closing costs and which offer lower interest rates and more affordable payments than standard conventional loans. You'll want to meet with someone in person to get all of your questions answered. Any good lender with VA approval can help you.
