I can think of couple other waysLiterally the only way to sort out the housing crisis is to limit bad immigration and build more homes. Thats it. Supply and demand. Reduce demand, increase supply.
Tax empty homes, start with council tax
Tax second/third/20th properties
make homes a worse place to invest your free money
Boom, there is more supply and the ever increasing house prices stop increasing and allow ACTUAL supply and demand to regulate the market
Well, should avoid the "boom", do it gradually.
