NEW: transactional data on your property valuation report

Average closing price as a part of CASAFARI's Comparative Market Analysis report

CASAFARI’s property valuation reports incorporate transactional (closing) price data for the Portuguese and Spanish markets. Estate agents can compare average closing prices against average asking prices, establish realistic expectations with clients upfront, calculate negotiation margins, and close real estate deals faster. Discover why transactional data is essential and how to find it in CASAFARI.

How does transactional data benefit your real estate business?

1. It helps the agent face the prices of a specific market realistically

No matter whether you’ve just started working in a market or if you’re looking for property outside of your area for a special client, with CASAFARI’s transactional data at your disposal you will always know how the market behaves without the need for previous experiences.

2. Transactional data helps you strategise the acquisition and sale of property

Imagine that you identify that the type of property you’re about to put on the market is usually sold for 10% less than the asking price in your market. In this case, you will know to charge around 10% above the desired price, already counting on this negotiation margin.

The same goes for when you’re buying a property for a client: the agent can feel free to look for properties slightly above their client’s budget, already counting on negotiating to lower 10% of the price.

3. It sets your clients expectations

In an area where the demand is higher than the amount of properties available on the market or in which there is a lack of a certain kind of asset, buyers are forced to compete for real estate, making higher offers and raising the transactional prices once again.

On the other hand, when an area has a decrease in demand or is going through times when buyers are facing a limited payment capacity, they will probably try to negotiate prices. In situations such as these, the asking price will be different than the actual transaction price.

When you have access to CASAFARI’s transactional data, you don’t need to wait until you can feel the market. Your seller client already knows up front if they should prepare to consider different proposals, as well as your buyer client will be aware of how bold they can be when selecting the properties interesting to them.

4. Transactional data leads to faster deals

When the agent knows how the buyer or seller is going to react, it’s like taking a shortcut: there’s no need to study the market, they can make offers or put property for sale more assertively, already aware of what they need to seal the deal.

Want an example? Imagine you’re selling a property in an area where residential properties show a 10% negotiating margin. You can settle an agreement with the owner in which you are allowed to automatically accept any offer to buy the property for 10% less (or a smaller margin) than the asking price.

This is only possible if you know what’s according to the market and what’s outside of an acceptable negotiation for that area.

Frequently asked questions

What is the difference between asking prices and closing prices in CASAFARI?

Asking prices represent the listed prices of properties indexed from online sources, reflecting initial seller expectations. Closing prices (or transactional data) show the actual values for which properties were sold. Comparing both figures allows estate agents to evaluate exact negotiation margins between asking prices and completed transactions in a specific market.

Where does CASAFARI source its closing price data?

CASAFARI sources closing price data from official public institutions and notary records, such as INE in Portugal and Notariado in Spain, alongside open data initiatives across European markets. Additionally, closing prices include transactional data reported at company level directly by CASAFARI’s clients. This ensures reliable, market-aligned benchmarks for property valuations.

How does transactional data help estate agents negotiate with buyers and sellers?

Understanding local transactional data enables estate agents to set realistic price expectations with property sellers upfront. Agents can establish pre-agreed negotiation margins, allowing them to accept suitable offers more efficiently. For buyers, transactional figures indicate realistic room for price negotiation, leading to faster deal completions.
