I don't like this line of reasoning because it's largely just crystalizing a loss. We have this in the UK - houses of multiple occupancy. It's a great idea where you take a home that in the 1980s would house a family and split it into 5 flats where each person can rent 10-20 square metres each. I would much rather someone did something to address the fact that the average family in the UK can afford roughly 1/5th the…
This isn't correct. When a house is split into multiple flats, they're individual flats rented out under separate agreements and not a HMO.
A HMO is when that house is rented to a group of people who are unrelated to each other (i.e. not of the same 'household'). They are generally jointly and severally liable (under an AST). They each have a bedroom and share kitchen/bathroom/common areas. HMO's have stricter health & safety regulations. For example, doors must be the automatically closing fire doors that you get in public buildings.
