Roughly $13–$26 per $1,000
Combined full-value rate — county + town/city + school district, per $1,000 of market value (FY2025). On a $300,000 home that's about $3,983–$7,924 a year before the STAR break.
A planning estimate, not a bill. Your exact rate depends on your school district and any village. Confirm with the assessor.

Good to know
- • Your assessed value usually isn't your market value — ask for the equalization rate.
- • Register for STAR; new applicants generally receive a credit instead of an automatic exemption on the bill.
- • Outside the cities, check the well, the septic, and the FEMA flood map before you buy.
