- Property boundaries
- Basic ownership and mailing info
- Flood-zone indicators
- Deed Automation
- Contact Information
- Satellite View
- Navigation Option
- A simple preliminary site-plan view (when available)
Do I need real estate experience to use BlockX?
No, it’s so easy a caveman can do it.

Daily! Ownership and tax information are refreshed daily from the County Clerk’s Office.
What if I see an error on a property?
Contact us with the address or parcel ID and a description of the issue, and we’ll review it against official data sources.
