Rent entire house vs by the room

[Ben Sorochuk]

I've got my first house a few months ago, and currently househacking it. It's going great, it's got 7 rooms. I'm living in a room and renting out the rest. Mortgage: $3650. Rent income: $5100. I'm seeing other houses that have a lot of rooms relative to the square footage, like houses that are 2000 sq ft and 7 rooms and considering buying more houses and renting them out by the room. If I rented the house to a single tenant I'd get maybe $3000/month. If I rented by room I could get $6000/month. Obviously I will have to manage more tenants and deal with more short term type tenants but it seems like a slam dunk home run. Is there a reason this isn't done as frequently? Obviously it's more involved but the way I see it, if I buy multiple properties and rent out each entire house to a single tenant, I'll basically have to deal with more hassle when I could get comparable cashflow with just one property that's rented by the room.
