I'd say for #1, whoever buys this unit will probably need to shell out another $50k to cover that 5500sqft brown dirt in front and back, and add some irrigation. Then they'll also be shelling out $66/month on hoas.
It's a long way before things start to normalize. My hunch in is some folks in CV are just going after their asking price, and if they can't get what they want, they're just adopting a wait and see approach.
