Online property valuationLooking for an online property valuation that’s trustworthy and done in seconds?
CASAFARI's Valuation & Market Study values a home in seconds from comparable properties: current listings and, in Spain, Portugal, France, Italy, Poland and Austria, registered sales from official sources. Estate agents choose the comparables, see the asking-price trends of the area and share a branded report with the owner, so the asking price they propose rests on evidence the client can read.
Show the owner where the market is heading
A valuation convinces when the owner sees the market behind it. Area Insights shows how asking prices and price per m² are moving in the area, how many homes are for sale and how they are distributed by price, across the 16 countries CASAFARI covers.
Put the trend next to the estimate and explain, with the owner, why a property priced in line with the market sells sooner.

Check each property's history in Property Sourcing
Property Sourcing keeps the history of every property: each change in asking price and condition, every agency that has advertised it and how long it has been on the market.
Before you meet the owner, you know whether the home was listed before, at what price and with whom. Our help centre explains how to use the property history.

What professionals say
CASAFARI’s valuation function helps us to objectively value properties and set realistic market prices. CASAFARI’s valuations and detailed market analyses open up additional opportunities for our company to increase sales.
CASAFARI helps us a lot when it comes to making property valuations and, therefore, in selling properties faster. It is a powerful tool to propose an asking price to the client, since it’s based on actual real estate data.
CASAFARI gives me confidence in my pricing. Thanks to a high density of comparative data and also the possibility to make property-related adjustments, I have the well-founded arguments on my side when in front of owners and prospective buyers.
I get to define an asking price much more aligned with market conditions, avoiding overpricing the properties.
Certainly the conversion of our valuations went up by 25% compared to the way we did it previously.
Registered transaction prices from official sources
CASAFARI holds registered transaction prices: what homes actually sold for, taken from official sources in Spain, Portugal, France, Italy, Poland and Austria, and not only what they were advertised at. Every comparable, valuation and market study you build can draw on them.
- Comparables: sold homes with a real closing price carry a purple “closing price” tag and are added automatically when the valuation finds them.
- CMA: the estimate multiplies the average price per m² of your selected comparables by the property's area, so comparables with registered prices count towards the value.
- Market Study: see the average closing price for the kind of property you are valuing in a chosen area, next to current asking prices.
- Property History: every registered sale around the property in Spain, France, Italy and Poland, and how the average closing price in the area has developed. In Portugal and Austria it shows the development of aggregated official statistics for the area.

Frequently asked questions
How does CASAFARI's online property valuation work?
CASAFARI's Valuation & Market Study finds listings and registered sales similar in location, size and features to the property you are valuing. The estimate multiplies the average price per m² of the comparables you keep by the property's built area, and you can add or remove comparables to reflect what you know of the home. Our help centre explains how the estimated value is calculated.
Does CASAFARI have registered transaction prices?
Yes, for Spain, Portugal, France, Italy, Poland and Austria. CASAFARI uses official sources, listed country by country on this page, and shows the registered prices next to asking prices in Comparables, CMA, Market Study and Property History.
