What does it mean for the seller? It means he's got his house SOLD!

Congratulations!
There are certain closing/loan costs in a VA loan which the buyer is not allowed to pay for. Talk with a mortgage lender you trust (not necessarily the lender the buyer will be using), and have them give you a break out of all the seller-paid loan expenses. Also talk with an escrow officer (if your state uses title companies for closing) and they can also fill you in.
Again, congratulations on a sale!
Almost forgot, there are appraisers that are approved to do VA loans. I did not think the appraisal was any more stringent that usual. There are guidelines that they will follow and will do a basic home inspection. The only downside that I noted is just that it may take longer to close if there's not a VA appraiser available immediately.
