“Aren’t market value and assessed value two different things?”
Yes, it would take more research to know the truth. Assessed values typically trail actual values by 2-3 years. Your tax assessment continues upward for a year or two when the market turns down, and taxes keep going down early in a new upswing in prices.
Oh, and Cuomo probably didn’t bar entry due to assessment, but due to code violations. It’s common.
