Surely this works in a short timeframe where a landlord can make a tactical decision to let the property sit empty rather than rent it out for less than a threshold. Landlords can even collude on a minimal rent below which they will not rent. (Basically "hold the line"). But how is this sustainable in the long run? The money for the original mortgage has to come from some place. Not all landlords have an infinite supply of money to keep this practice going on for a few years. (There is no VC funding available for them).

With commercial units (eg - downtown San Francisco) it is even harder because with remote work, the jobs are never coming back to the city.
