Challenging property tax in queens county, NY

[Casida Caines]

I own two mixed-use properties on the same block. However, the property taxes are triple the cost of the first one I purchased in 2019 compared to the other I bought in 2021.

For the past two years, I've attempted to reach the finance dept for assistance, but with COVID at the time and needing more experience, I'm still left with this hefty bill each year.

Is there anyone who can assist (willing to pay for service, of course) or refer me to someone who handles this matter in Queens County? It's widespread in Long Island, but most people there don't work in Queens County.
