I would review each thoroughly and then write an email to protest the validity of it.

If your landlord does not do this, you have two choicesYou can refuse to pay the increase, orYou can pay under protest and later sue your landlord for the amount you were overcharged.

It is the appraisal district's job to use whatever legal methods are at their disposal to arrive at their own value, which the property owner can then protest.

With the pandemic and now the protests, I am finding it hard to find open showrooms.Where are you guys finding open showrooms?

Now fast forward to 2014-2015, > 10 years has passed and not a single major attack has occurred in Manhattan, so they decided to close these offices for the most part and moving most back to Manhattan.  5 years later Covid-19 happens, and now protest & riots where you can't safely go into an big office building anymore in NYC. 

MLK protested, BLM is NOT "protesting" as it burns areas down. 

As to what @Marc Winter said, I think the protests lack of social distancing and the fact that no one seemed to care shows that most of the rules set down are political and not truly based on science.

…This is really a protest that’s aimed at the government.”A number of New York-based tenant groups that have had some recent success pushing for rent-related reforms, including the Upstate/Downstate Housing Alliance and New York Communities for Change, called for a statewide strike of 1 million renters earlier this month.About one-third of U.S. households are renters, and nearly half of them were paying more than 30% of their incomes on rent and utilities before the coronavirus pandemic struck, according to the Harvard Joint Center for Housing Studies.

Now that we are here other than protesting the government actions what else can we do to take control of our REI businesses.
