This really can only answere d by having a tad more info. If you are referring to Bronxville Village and school district, they are significantly higher than those in the surrounding areas that have Bronxville address but are actually Yonkers or Mount Vernon. A house in Bronxville that has an annual tax bill of $50,000 might only have a $10,000 to15,000 bill in a Yonkers location with a Bronxville address.
Feel free to contact me if you need me to elucidate.
