Property-tax assessment figure that should not be mistaken for a lender's valuation decision.
Assessed value is the value assigned to a property by a municipal or provincial assessment authority for property-tax purposes.
Borrowers often see the assessed value on tax or municipal records and assume it should match the value a lender will use. That assumption is often wrong.
Assessment authorities use their own timing, methods, and mass-appraisal frameworks for tax purposes. A lender making a mortgage decision is usually more interested in current market support and may still require a fresh appraisal.
This means assessed value can be useful context, but it is not a substitute for appraised value in a mortgage file.
| Question | Assessed value | Appraised value |
|---|---|---|
| Main purpose | Property-tax administration | Mortgage underwriting and transaction support |
| Timing | Based on assessment-cycle methods and dates | Based on the valuation ordered for the file |
| Who relies on it most | Tax authorities and property owners reviewing tax records | Lenders, insurers, and underwriting teams |
| Can it replace the other number? | No | No |
A homeowner sees that the assessed value is well below recent neighbourhood sale prices and assumes the lender will lend against the higher number without question. The lender may still order an appraisal because assessment records are not designed to replace transaction-specific lending analysis.
Assessed value is not automatically the same as market value.
Borrowers also sometimes think a low assessed value helps reduce the amount needed for a mortgage. It may affect tax bills, but it does not by itself determine the lender’s supported security value.
Assessment cycles, appeal results, and provincial systems differ. Assessment numbers can lag changing market conditions materially.
