Property Value Intelligence
Property Value Intelligence
Automated property valuation support built on comparable evidence, market context and transparent uncertainty.
Important disclaimer
Valuations are for reference only and should not be the sole basis for any purchase or investment decision.
Property Value Intelligence is not an official, certified, mortgage, tax or legal appraisal. Local data coverage and market conditions materially affect accuracy. Use a locally qualified valuer, appraiser, surveyor or other professional when the decision requires regulated or case-specific advice.
What it does
Property Value Intelligence turns property details, photos, listing links, comparable evidence and lawful public market data into:
- an estimated sale or rental range;
- a central reference value;
- price per square metre or square foot;
- ranked comparable properties;
- market trend and time-adjustment context;
- nearby infrastructure and location context;
- visible property-condition observations from photos;
- a transparent confidence score;
- a source manifest and missing-data note;
- a client-ready PDF when file generation is supported;
- an optional self-contained premium HTML dashboard.
Built for international markets
The Agent does not depend on one property portal. It first identifies the jurisdiction and then looks for the most defensible local evidence, normally in this order:
- completed-sale or cadastral records;
- official valuation or bank data;
- official house-price indices;
- licensed or user-authorized transaction data;
- permitted asking-price listings;
- infrastructure and geographic context;
- user-supplied evidence.
It supports local language, currency, date formats and area units. Availability and depth vary by market.
Who it is for
- real-estate consultants and agents;
- agencies pre-qualifying owners;
- property managers and landlords;
- owners preparing a sale or rental conversation;
- buyers who want a structured market reference;
- analysts reviewing comparable evidence.

How the estimate works
The Agent:
- validates the property profile;
- separates completed transactions from asking prices;
- normalizes currency, area, dates and property types;
- ranks comparables by distance, recency, similarity and evidence quality;
- screens outliers;
- time-adjusts evidence when a suitable local index exists;
- uses a robust weighted price-per-area estimator;
- applies only a bounded, evidence-backed photo-condition adjustment;
- creates a low, reference and high estimate;
- explains confidence and sensitivity.
The included calculator is transparent and reproducible. It does not claim universal accuracy.
Photo analysis limits
Photo analysis can describe visible maintenance, finishes, renovation, natural light, external condition and other property features. It does not identify residents or infer income, ethnicity, nationality, religion, family status, disability or other protected traits. It does not prove structural safety, hidden defects or legal compliance.
Data access and privacy
Exact addresses and photos can be personal data. The Agent minimizes external queries, does not use property data for marketing and should redact faces, plates, documents and contact details from client-facing reports.
The exact external sources vary by market. They may include official statistics offices, land registries, housing authorities, mapping services and user-provided listing URLs. The configured LLM provider processes the user's prompt and any photos. Every external recipient must be disclosed before publication and the services actually used should be listed in each report.
Example prompts
Estimate the sale value of this T3 apartment in Porto. It has 118 m², two parking spaces, a balcony, lift and was renovated in 2022. I have attached eight photos and three comparable listings. Produce a client-ready PDF in European Portuguese.
Review these six sold comparables for a three-bedroom house in Austin, Texas. Reject weak matches, time-adjust the remaining evidence and create a valuation range with a confidence explanation.
Estimate the monthly rental range for this apartment in Singapore. Use official or permitted public sources, explain what data was unavailable and produce the premium dashboard.
I only have the postcode, property type and area. Give me a quick range, clearly state the evidence limitations and tell me which three facts would most improve confidence.
What the Agent will not do
- certify or sign an official appraisal;
- guarantee a price or transaction result;
- fabricate property or source data;
- bypass restricted websites;
- use protected characteristics or demographic proxies;
- replace a licensed valuer, surveyor, lawyer, lender or tax professional.
