The video [1] was interesting, although the dead comment seemed to completely ignore the video's [1] main point, where Louis talks about a hypothesis [2] where in New York City there may be an incentive structure between real estate investors and banks which is creating a market failure. The hypothesis [2] is that a building's assessed value is based on the rental prices that the landlord asks for even if nobody will reasonably pay those rents. The hypothesis speculates that, if a building's assessed value is lowered, it could trigger conditions in loan contracts that penalize the landlord or investor. Because of this, there may be an incentive for the landlord to keep buildings vacant instead of lowering their prices to market rate.
