Rent by the room-friendly PM in Northern VA?

[Jeremy Porto]

My sister does rent by the room in northern VA and currently she is managing them herself. I am trying to help her grow and part of that would be passing the property management duties to someone else. Are there any PMs in northern VA that work with rent by the room investors? It's not the strategy that I use, but i know there are some challenges with the strategy so I'm looking for a PM that has experience with this already.
