arguably asset price is built on scarcity vs demand everything else is all second order really.
No, asset price is built on yield, not on scarcity. That is exactly my point.
It's a bit brain-melting, but once you realise it, the talk of NIMBY-ism etc. is just irrelevant.
If you add more assets with a good yield, assuming that yield is better than bonds etc., then those assets will get bought.
The only other brake on that is diversity of portfolios, but it doesn't strike me as particularly important, especially if many landlords only own a few properties.
Yes, but isn't yield due to scarcity?
For example right now there's more demand than supply for a 2 bed house for £2000pcm, but if we doubled the supply then there'd be competition and we'd end up at a much lower price?
