Property Valuation: how has it evolved and why is this so important for the property market?

Since 2018, property valuation has evolved from a fragmented, time-consuming search across property portals into a rapid, data-driven process. CASAFARI aggregates big data from over 16,000 sources and 120 million listings into accessible charts and comparables so estate agents can recommend a well-founded asking price in minutes, transforming daily real estate workflows. Learn how to make a property valuation with CASAFARI to streamline client appraisals.

Through a complete analysis using CASAFARI’s Property Valuation and Market Study tool, you can suggest the best asking price to the owner and win the client over with comprehensive data reports.

This was the issue that led us to Mila Suharev, co-founder of CASAFARI, in charge of product and data. In three short questions, we clarified the importance of this tool and how you can get more out of it, within the CASAFARI network.

After all, how can we know the estimated value of a property?

Less than half a dozen years ago it was difficult to find the answer to that question. The information was too fragmented and it was necessary to search through all the real estate portals, almost always too long and without success. Another problem was ensuring the veracity and quality of that data.

As we know, the fair price in the valuation of a property cannot be justified intuitively, it is necessary to have a basis. Therefore, CASAFARI’s big data has brought disruption to the property market.

Today we are able to optimize this task and collect the real values: CASAFARI has the largest base of comparables, gathering all available real estate data, in the respective market in which it operates: Portugal, Spain, France and Italy – and we don’t stop there. In minutes, it is possible to download a complete report, personalised and adapted to each case.

Is any property valuation tool suitable for this research?

Effectively, no. In order to collect real values and create a report based on market data, it is essential that the platform collects the total number of available assets. And this is not possible by resorting only to the universe of searches within a real estate portal: much more sample is needed, it has to be significant.

Therefore, nowadays, only by accessing CASAFARI’s Property Valuation tool it is possible to extract a report that, more than personalized, is a true mirror of the real estate offer. We are the only company tracking more than 16 thousand sources and 120 million listings every day and growing!

How does CASAFARI differentiate itself in Property Valuation?

CASAFARI is much more agile in research and collects a very complete history of information, which is gold in the client’s hand. In addition, a marketing price is suggested, in an editable report, with the option to consider single ads or the entire market offer. This is where we differentiate ourselves: there are no European players that collect data using machine learning, as our teams have the ability to do.

Thanks for all the insights, Mila!

Frequently asked questions

How does CASAFARI calculate the estimated asking price of a property?

CASAFARI uses machine learning to aggregate and deduplicate property listings across the entire market, building a complete database of comparable properties in any target location. The platform analyses these comparables along with their historical pricing data to suggest a fair marketing asking price in minutes. Estate agents can then review, accept, or adjust the suggested asking price to match their client’s strategy.

Why is searching a single property portal not enough for an accurate property valuation?

A single property portal holds only a fraction of market listings, which is not a sufficiently large sample to reflect true market conditions. Conducting an accurate valuation requires aggregating data across thousands of sources to guarantee data veracity and quality. Accessing the entire market offer ensures that estate agents base their valuations on comprehensive supply data rather than isolated listings.

Can estate agents customise CASAFARI’s property valuation reports for their clients?

Yes, CASAFARI allows estate agents to create a personalised valuation report in minutes as an editable comparative market analysis. Agents can choose whether to evaluate individual listings or the broader market offer, adjust the suggested marketing price, and export clear charts to present to property owners.

Does CASAFARI include both asking prices and closing prices in its valuation tools?

Yes, CASAFARI indexes asking prices from listings across thousands of sources while also integrating closing prices from official open data, notary records, and client-reported transactions. This dual approach allows real estate professionals to evaluate current market supply alongside verified historical transaction values. As a result, agents gain a complete perspective on both listing expectations and actual property sales.

How can developers or agencies automate property valuations via API or AI assistants?

Developers and real estate teams can automate comparative market analyses by integrating the CASAFARI Comparables and Valuation API documentation into their internal tools or connecting AI assistants via Casafari MCP. This allows agencies to generate property valuations and retrieve real-time market data directly inside their own software workflows. To get started, users can sign in to the CASAFARI platform and manage their integration tokens.
