Just to play devil's advocate here, please keep COVID in mind with this model. I manage a handful of large (6/7/8 bedroom) rowhomes in the Columbia Heights/Petworth/Shaw areas that often functionally operate as a room-by-room rental (i.e. there's a master lease, but people are free to find their own replacements and move out, etc.) While we/our tenants have had zero trouble filling these rooms in the past few seasons, this spring/summer was a bit rough, with many people explicitly referencing COVID as their reason for leaving these homes or not moving in. What's more, one of our partners is a large, national room-by-room/co-living rental service and they've had so much difficulty renting by the room that they're breaking/trying to unilaterally renegotiate their leases with us. Not fun.
Yes, this might be over in a few months but I do think there will be a knock-on effect in some cases for communal living like this. And while I'm not personally a fan of most of Capitol Heights, yes, I'm sure you can find people to fill it at the right price. The question is whether it's worth it to deal with the headaches that come with the kind of tenants who may be willing to live with strangers in the middle of a pandemic at a budget rate.
If you're determined to go this route, please keep the layout in mind. IMO, shouldn't be any more than two bedrooms using each full bathroom.
