Checks we do not perform
Confirm these yourself before you bid. We would rather tell you they exist than let you find out after the hammer falls.
- Special assessments and Mello-Roos that survive the sale
- Federal tax liens (the IRS has 120 days to redeem)
- Title insurability — most carriers wait a year after a tax deed
- Access, easements and whether the road is really a road
Checks we perform on every parcel
- Wildfire history against CAL FIRE perimeters back to 1950
- Current zoning code and what the county lets you do with it
- Assessor roll: use code, improvements, assessed value
- Sale history: prior offerings, withdrawals and results
Always free
We don’t paywall safety information.
Fire history, county pages and sale results are free to anyone, signed in or not. If a parcel burned, you should know that whether or not you ever pay us.
Enrollment
Pay for the course and the table. Not for the safety data.
