This is the line item that makes a detached mid-Island home actually affordable to carry. So let's be precise.
Staten Island's effective property-tax rate sits around 0.85% of market value, the lowest effective rate of any borough in the city. On a typical $775,000 New Dorp home, that's roughly $6,500–$7,000 a year. For a free-standing house with a yard, a driveway, and a walkable main street, that number surprises people in the best way.
And it's not just low, it's predictable. New York City taxes one- to three-family homes as Class 1, on a small fraction of market value, and caps how fast your assessment can rise: no more than 6% in a single year, and no more than 20% over any five years. Your bill can't lurch upward the way it can in places that revalue aggressively. You can plan around it.
The honest caveat: what you save in tax down toward the beach, you can give back in flood insurance. On higher ground west of Hylan, near the Lane, the math stays firmly in your favor, but on a block close to the water, always price the flood insurance before you price the house.
