We are 10 years into an expanding economy into one of the longest expansions ever. Interest rates are near all time lows and despite this the US it’s starting to spend more on interest than the military. Commercial real estate loans amortize over 30 years but need to be refinanced every 5-10 years so if rates go up.... Is it a good idea for SF to accommodate the tech bubble? There have been other tech bubbles and many country level and regional single industry bubbles in the past. Why is this bubble different? Not changing zoning and reducing the risk of SF turning into a sea of unfinished projects seems like the rational thing to do.
