If you've followed the housing debate in the UK you may have come across the terms in the title above:
These terms are also used in other English-speaking countries. What they don't have outside England Wales is "SULTANA":
For the first three, it's all an argument about the familiar trade-offs involved in new development: the externalities of building new infrastructure and housing. There are various local resources that operate as club goods or common pool resources, e.g., schools, roads, pubs, social trust, and so on, and there is the impact on the rest of society from having more or less housing.
SULTANAs treat these as second-order effects relative to the impact of tenure: if new high-density housing is going to be produced, owning some of it should not expose the new owners to the severe economic and psychological harm which currently attends upon much of the leasehold housing stock (and some of the freehold houses on new build estates), nor strengthen the existing predators in the new build housing management sector.
For the SULTANA, any new multi-occupancy housing stock should be Build-To-Rent or share-of-freehold. Sadly, Lord Bailey's amendment to fix this was defeated on the final day of the 2019-2024 parliament.
