For the county you are in if you live in Greece, NY you can access the Monroe County real property portal. If in Ontario or Wayne County you would use the counties website. I have included the portal for Monroe County. As for any website like Trulia etc it is up to the agent to list. As always check with your agent. If you are in need of someone to assist you in any way or answer your questions about real estate, give me a call. I would be glad to support you in any way possible. http://www.monroecounty.gov/apps/propertyapp.php
Property taxes are a variable:
Usually, they will change with the new purchase of the house:
If the house was bought at the peak, they will go down.
Most of the time they reflect the new selling price.
But Assessors and Counties vary.
Please talk to your Realtor to get the latest skinny.
