I'm not sure what you're trying to imply here. You should spell it out explicitly.
It's entirely different if you're buying the housing already built; there's no productive activity, you're just a rentier and do not benefit at all from falling housing prices.
The differences in interests between an asset holder and a productive builder are night and day.
Right... my point is that the costs are not far below the eventual sales price. That's why construction is slowing down.
And as mentioned several other times, it's actually not as simple as cost > sale price. It's margin > margin of alternative investments of similar scale and risk profile.
Or land ends up better value left as suburban house than developing up.
Or they build where sale cost - build cost is maximized. I.e. different city.
Governments need to build more housing. Make it bland so snobs can price discrimnate themselves to buy builders' homes. Why thrifts by the government home for value for money (and quality).
Government doesn't need to make a profit due to taxation.
They're just gonna pay builders a sum anyway so it's not like they need to shoulder the full upfront cost anyway.
