Mass assessments assume average condition — they don’t see your failing roof, old systems, foundation issues, or storm damage. If your home is in worse condition than the assessor assumes, documented problems and repair estimates can bring the value down.
What counts (and how to prove it)
- Major systems / structure: roof, HVAC, foundation, plumbing, electrical, water damage, mold.
- Deferred maintenance & damage: dated kitchens/baths, settling, code issues, post-disaster damage.
- Proof: dated photos of each problem, contractor estimates or inspection reports, and (if available) an insurance claim or engineer’s report.

Re: Condition-based reduction of assessed value
Owner: [Name] Parcel / account number: [number]
Property address: [address]
Noticed value: $[amount] My opinion of value: $[amount]
To whom it may concern:
The assessed value of my property does not reflect its actual condition as of the
valuation date. The property has the following condition issues, which a typical
buyer would deduct from the price:
1. [Roof - end of life] Estimated cost / impact: $[ ]
2. [HVAC - failed/original] Estimated cost / impact: $[ ]
3. [Foundation / water damage] Estimated cost / impact: $[ ]
4. [Other] Estimated cost / impact: $[ ]
Total documented impact: $[ ]
Given these conditions, I request that the assessed value be reduced to $[amount],
or that the property's condition/grade be lowered accordingly.
Enclosed: dated photos, contractor estimates / inspection report[, insurance
claim / engineer's report].
Sincerely,
[Your signature]

How to send it
Photograph every issue with dates, and get written estimates — a board trusts a contractor’s number far more than your description. Offer access for a re-inspection. File by your appeal deadline with the informal review or formal appeal.
Notes. Condition evidence pairs well with comps — ideally use comps in similar (poor) condition, or argue your home should sell below average-condition comps by the repair cost. If you later make the repairs, expect the value to rise again. Condition is judged as of the valuation date, which varies by jurisdiction. General information, not legal or appraisal advice.
