We must have a rent holiday if those businesses and their workers are to survive.
We'll get a lot of rent forgiveness naturally. If a strip mall has some tenants who cannot make rent in this crisis, who are they going to get who can pay? The pragmatic approach is to keep your existing tenants, because their survival is your strip mall's survival.
Many land owners would already prefer to leave their buildings empty for years over even considering negotiating on rent. I doubt anything can change their minds.
For example let’s say I have a 100 unit apartment building. If I maintain a 20% vacancy rate target I can charge an average of $1000/mo/unit. But to set a price at which my vacancies get filled very quickly, to hit a 5% vacancy rate, maybe I need to charge $700/mo/unit. In that case I’m making less money than before - $80k/mo vs $66.5k/mo.
