Sell your building. Your taxes went up because your property value went up. You aren't entitled to a profit on rent. If you sell your building below what it's valued at, you'll still make a hefty profit, and it'll cause the value of other buildings to lower.

Land owners seem to feel entitled to businesses with no risk. Costs are always passed down, even if it makes people homeless. I'm more than happy with you going out of business if an event that makes you richer isn't an event that you can handle in terms of cost.
