I would get a referral from your MD guy for someone who can handle the VA side. That way everyone has full disclosure and you won't have two agents competing against one another. Things can get dirty when that happens and you don't want to get caught in the middle
Good luck !
You could ask your great Maryland agent to refer you to a great agent in Virgnia to help you with the area(s) you are interested in. The two agents can work out the details regarding referral fees. I wish you the best in finding your perfect place.

Nice you are concerned regarding agents who are working on your behalf
But I know agents crossing the river all the time. It's your comfort or discomfort level that should guide you through.
