>You can check what the new taxes are on the JC website, and see how much your landlord was raised. Then you've just got to figure out that amount divided by the number of tenants, and assume that's the amount you'll be raised, if not a little more to cover the rising cost of everything else (insurance, new trash/water fees, incidentals)

This might not be a realistic approach. You are certainly underestimating the impact of new increases in trash and sewer fees by using the words "a little more." Some people are reporting getting major increases in their trash and water bills. And, insurance companies are about to start introducing major increases in their rates, as evidenced by recent filings with the state insurance regulators. Yeah, taxes are front and center in the conversation, but homeowners are getting walloped this year and the next.
