It matters whether the margin is higher than other investment opportunities of similar scale and risk profile.
Already, the answer is very often no. In Austin, the answer will increasingly be no. That means people will not finance new construction, so if demand continues to grow it will outstrip supply and prices will go back up until the margin on new construction exceeds that of alternative investment opportunities of similar scale and risk profile.
And indeed that amount of uncertainty: will I be allowed to build eventually? How long will I have to pay interests on assets before I'm allowed to build? Can I actually build what's specified in code or will discretionary processes arbitrarily change what I'm allowed to do, 18 months into the project?
I guess I don’t see where we disagree?
