Are Rent by the Room Townhouses Multifamily?

[Shane Duncan]

I am looking at a 7 bed 3 bath townhouse that is currently being used for student housing near a prominent university. It is listed as a single rent value but I believe they also rent by the room. 
Do lenders consider this a multi family and require commercial financing or is it considered a single family? It has a large shared kitchen, common areas, and shared bathrooms.
