| property-assessor | Assess a real property from an address or listing URL and produce a decision-grade summary. Use when a user wants fair value, comps, rental or STR viability, carry-cost review, HOA or insurance risk analysis, or offer guidance for a condo, house, townhouse, or similar residential property. Prefer when the task should discover and reconcile multiple listing sources from a street address first, then give a buy/pass/only-below-X verdict. |
Property Assessor
Start from the property address when possible. Treat listing URLs as supporting evidence, not the only source of truth.
Inputs
Accept any of:
- a street address
- one or more listing URLs
- an address plus user constraints such as investment only, owner-occupant, long-term rental, STR, or distance to a target location
Core workflow
- Normalize the address and property type.
- Discover accessible listing or public-record sources for the same property.
- Establish a baseline fact set from the best available source.
- Cross-check the same property on other sites.
- Pull same-building comps for condos or nearby comps for houses/townhomes.
- Underwrite carrying cost with taxes, HOA, insurance, and realistic friction.
- Flag risk drivers before giving a verdict.
- End with a specific recommendation:
buy,pass, oronly below X.
Approval-averse / chat-safe behavior
When operating from chat surfaces such as WhatsApp, Telegram, Signal, or other messaging channels, prefer workflows that do not trigger host exec approval prompts.
Use this priority order:
web_searchfor discoveryweb_fetchwhen page fetch is sufficientweb-automationone-shot extraction or accessible all-photos pages only when needed- interactive browser/gallery automation only as a last resort
Rules:
- Prefer accessible listing text, public mirrors, and scrollable all-photos pages over custom gallery traversal.
- Avoid fragile interactive gallery flows if they are likely to require approval or bounce the user into Control UI.
- If a richer photo pass would require approval, do not silently force that path first. Continue with the best approval-free workflow available and clearly lower confidence if needed.
- Only escalate to approval-heavy browser interaction when there is no reasonable alternative and the extra fidelity materially changes the assessment.
Source order
Prefer this order unless the user says otherwise:
- Zillow
- Redfin
- Realtor.com
- HAR / Homes.com / brokerage mirror pages
- county or appraisal pages
Use the web-automation skill for rendered pages and anti-bot-heavy sites.
Use web_search sparingly to discover alternate URLs, then return to web-automation for extraction.
Minimum data to capture
For the target property, capture when available:
- address
- ask price or last known list price
- property type
- beds / baths
- sqft
- lot size if relevant
- year built
- HOA fee and included services
- taxes
- days on market
- price history
- parking
- waterfront / flood clues
- subdivision / building name when applicable
- same-building or nearby active inventory
- listing photos and visible condition cues
- included appliances and obvious missing appliances
- flooring mix, especially whether carpet is present
Photo and condition review
Always look at the listing photos when they are available. Do not rate a property only from structured text.
Required photo-access workflow
When the source site exposes listing photos, prefer the most accessible all-photos view first. This can be:
- a scrollable all-photos page
- a photo grid
- an expanded photo list
- or, if necessary, a modal gallery/lightbox
Use web-automation for this. Preferred process:
- Open the listing page.
- Click the photo entry point such as
See all photos,See all 29 photos,Show all photos, or the main hero image. - If that opens a scrollable all-photos view, grid, or photo page that clearly exposes the listing images, use that directly for photo review.
- Only use next-arrow / slideshow traversal when the site does not provide an accessible all-photos view.
- If you must use a modal/lightbox, verify that you are seeing distinct images, not just a gallery preview tile or repeated screenshot of the first image.
- Review enough images to cover the key rooms and exterior, and for smaller listings aim to review all photos when practical.
- If photo access fails or is incomplete, say so explicitly and do not claim that you reviewed all photos.
Minimum honesty rule: never say you "looked at all photos" unless the site actually exposed the full set and you successfully reviewed them. A gallery landing page, collage preview, repeated first image, or a single screenshot of the listing page does not count as full photo review.
What to inspect in the photos
At minimum, note:
- overall finish level: dated, average, lightly updated, fully updated
- kitchen condition: cabinets, counters, backsplash, appliance quality
- bathroom condition: vanity, tile, surrounds, fixtures
- flooring: tile, vinyl, laminate, hardwood, carpet
- whether carpet appears in bedrooms, stairs, or living areas
- obvious make-ready issues: paint, damaged trim, old fixtures, mismatched finishes, worn surfaces
- visible missing items: refrigerator, washer/dryer, range hood, dishwasher, etc.
- any signs of deferred maintenance or water intrusion visible in photos
- exterior/common-area condition when visible
- balconies, decks, sliders, windows, and waterfront-facing elements for condos/townhomes near water
If photo review is incomplete
If photos are weak, incomplete, blocked, or the gallery automation fails:
- say so explicitly
- lower confidence
- avoid strong condition claims
- do not infer turnkey condition from marketing text alone
Mandatory photo-review rule
If an accessible all-photos view, photo grid, photo page, or fallback source exists, photo review is required before making condition claims. Do not silently skip photos just because pricing, comps, or carrying-cost analysis can proceed without them.
Before outputting Photo review: not completed, you must attempt a reasonable photo-access chain when sources are available.
Preferred order:
- primary listing source all-photos page (for example Zillow
See all photos/See all X photos) - HAR photo page
- Realtor.com photo page
- brokerage mirror or other accessible listing mirror
Use the first source that exposes the listing photos reliably. A scrollable photo page, photo grid, or expanded all-photos view counts. Do not stop at the first failure if another accessible source is available.
Zillow-specific rule
For Zillow listings, do not treat the listing shell text or hero gallery preview as a photo review attempt.
You must use only web-automation to:
- open the Zillow listing page
- click
See all photos/See all X photos - access the resulting all-photos page or scrollable photo view
- review the exposed photo set from that page
If Zillow exposes a page with a scroller that shows the listing photos, that page counts as the Zillow photo source and should be used directly.
Do not rely on generic page text, photo counts, or non-photo shells as a Zillow attempt.
Only fall back to HAR/Realtor/broker mirrors if the Zillow all-photos path was actually attempted with web-automation and did not expose the photos reliably.
A source only counts as an attempted photo source if you actually did one of these:
- opened the all-photos page / photo grid / photo page successfully, or
- explicitly tried to open it and observed a concrete failure
The following do not count as a photo-source attempt by themselves:
- seeing a
See all photosbutton - seeing a photo count
- reading listing text that mentions photos
- capturing only the listing shell, hero image, or collage preview
The final assessment must explicitly include these lines in the output:
Photo source attempts: <action-based summary>Photo review: completed via <source>orPhoto review: not completed
If completed, briefly summarize the condition read from the photos. If not completed, mark condition confidence as limited and say why.
Normalization / make-ready adjustment
Estimate a rough make-ready budget when condition is not turnkey. The goal is not contractor precision; the goal is apples-to-apples comparison.
Use simple buckets and state them as rough ranges:
- light make-ready: paint, fixtures, minor hardware, patching
- medium make-ready: flooring replacement in some rooms, appliance replacement, bathroom refresh
- heavy make-ready: major kitchen/bath work, widespread flooring, obvious deferred maintenance
Call out carpet separately. If carpet is present, estimate replacement or removal cost as part of the make-ready note.
Underwriting rules
Always show a simple carrying-cost view with at least:
- principal and interest if available from the listing
- taxes per month
- HOA per month if applicable
- insurance estimate or note uncertainty
- realistic effective carry range after maintenance, vacancy, and property-specific risk
Treat these as strong caution flags:
- high HOA relative to price or expected rent
- older waterfront or coastal exposure
- unknown reserve / assessment history for condos
- many active units in the same building or micro-area
- stale days on market with weak price action
- no clear rent support
Output format
Keep the answer concise but decision-grade:
- Snapshot
- What I like
- What I do not like
- Comp view
- Underwriting / carry view
- Risks and diligence items
- Verdict with fair value range and offer guidance
Reuse notes
When condos are involved, same-building comps and HOA economics usually matter more than neighborhood averages.
