property-assessor

Decision-grade residential property assessment with required photo review, comp checks, carry-cost underwriting, and explicit buy/pass guidance.

What this skill is for

• Assessing a property from an address, Zillow URL, HAR URL, or other listing source
• Reconciling baseline facts across multiple listing/public sources
• Reviewing listing photos before making condition claims
• Producing a practical verdict such as buy, pass, or only below X

Core workflow

1. Normalize the address and property type.
2. Build a baseline fact set from the best available listing or record source.
3. Cross-check facts on other sources.
4. Review photos before making condition claims.
5. Pull comps.
6. Underwrite carry costs and risk factors.
7. End with a clear verdict and fair-value guidance.

Required photo-review workflow

Photo review is mandatory when a listing source exposes photos.

Preferred source order:

1. Zillow
2. HAR
3. Realtor.com
4. Brokerage mirror or other accessible listing mirror

Rules:

• Do not claim condition from structured text alone when listing photos are available.
• Prefer accessible all-photos views, photo grids, or scrollable photo pages over fragile next-arrow traversal.
• If the primary source fails but a fallback source exposes the photos, continue with the fallback.
• If photo review is incomplete, say so explicitly and lower confidence.

Zillow and HAR integration

This skill now expects the dedicated web-automation extractors first.

Zillow

cd ~/.openclaw/workspace/skills/web-automation/scripts
node zillow-photos.js "<zillow-listing-url>"

Success means:

• the Zillow all-photos page opened, or
• Zillow's rendered listing shell already exposed the full direct image set and the extracted count matches the announced count

The returned imageUrls are the photo-review set. Review those images before making condition claims.

HAR fallback

cd ~/.openclaw/workspace/skills/web-automation/scripts
node har-photos.js "<har-listing-url>"

Use HAR when Zillow does not expose a reliable photo set. The returned imageUrls are the review set for the fallback path.

Approval-safe command shape

For chat-driven runs, prefer file-based commands under ~/.openclaw/workspace/skills/web-automation/scripts.

Good:

• node check-install.js
• node zillow-photos.js "<url>"
• node har-photos.js "<url>"

Avoid when possible:

• node -e "..."
• node --input-type=module -e "..."

Output requirements

The final assessment should explicitly include:

• Photo source attempts: ...
• Photo review: completed via <source> or Photo review: not completed

If photo review was completed, briefly summarize the condition read from the photos. If not, mark condition confidence as limited and explain why.
