Are apartment buildings being converted to Living Room rentals?

[Roger Simons]

A 1 br apartment would rent to 2 people, one in the living room.
A 2 br apartment would rent to 3 people, one in the living room.
A 2 br with den apartment would rent to 4 people.....

In many cities with high rental demand and lots of younger people that aren't home much this could really work and result in about 30% more revenue.  Sometimes 50% depending on the layout.  Unconventional?  Yes.  Lucrative, very much!

Taking this to the extreme would result in a total rebuild and layout alteration where the kitchen and possibly the bathroom are transformed into a rental spaces.  Communal facilities would be provided in the building.  This would especially appeal to people with eating problems as they wouldn't have much food on hand to tempt them when home.  And when they did eat they would be around others - peer pressure can be powerful.  Everything can help get you towards your goals of eating sensibly.

Converting the kitchen/bathroom could hugely affect revenue, especially if the kitchens were a little larger than normal.  Especially wider.  Some are very narrow.
