I've been hoping that this would change because the type of mid/low-rise multifamily housing we have in the United States is horrible. What I really hope happens is that ownership of multifamily real estate becomes much more fragmented. Imagine multifamily housing where each lot is the same as a single family lot. You can have varied types right next to each other (one building could house several seniors in small apartments, another could house several young people in smaller apartments, another could be the owner in a two floor "house" on the top to floors with rentals below, another could be a building comprised of entire floor flats that are each owner-occupied). They can be redeveloped so much more easily or repurposed. When an entire block is a huge multifamily building, it's pretty much impossible to change anything about it. But, we really need to also change how we finance these buildings. A big reason everything is the same these days is because the finance system underwrites them. The system is there for these other types of smaller buildings.
