Pro tips
How to Use Assessor Records in Your Search
Verify Ownership Before Making an Offer
Always confirm the legal owner of a property matches the seller. Assessor records are public and provide a quick ownership verification before you invest time in negotiations.
Compare Assessed Value to Asking Price
The county's assessed value isn't the market value — but a large gap between the two can signal an overpriced listing or an undervalued opportunity worth investigating further.
Research Tax History for Investment Properties
For investors, understanding a property's tax history helps you model carrying costs accurately. Look for delinquent taxes or sudden assessment jumps that could affect your ROI.
Check Parcel Boundaries and Lot Size
Confirm the actual lot dimensions and parcel boundaries match what's listed. Discrepancies can affect financing, permitting, and future development potential.
