Everything you need to know about ComplexInfo’s real estate portal to succeed in your real estate projects

Searching for real estate online often means juggling multiple sites, each with its own filters and limitations. The real estate portal of ComplexInfo offers a different approach, focused on project management rather than just browsing listings. Understanding what distinguishes this type of platform can save time and avoid unpleasant surprises.

Project management real estate portal or simple listing showcase

Have you ever spent an hour browsing listings only to realize, when contacting the agency, that the property had been sold two weeks ago? This discrepancy illustrates the difference between a portal that merely lists properties and one designed as an active tracking tool.

Several French portals have evolved in recent years into what Immo Matin calls “service platforms.” Specifically, this means that the portal no longer just displays photos and a price. It integrates performance indicators: click-through rate on a listing, contact rate, average time before the first visit.

For an individual, this data often remains invisible. On the real estate portal of ComplexInfo, the goal is to make this management logic accessible, including to buyers and sellers who are not real estate professionals.

Quality score of listings: what your real estate portal doesn’t tell you

In recent years, several portals have implemented algorithms that internally rate each listing. This score takes into account the quality of the photos, the consistency between the displayed price and local market prices, and the completeness of the information (area, number of rooms, energy performance diagnosis, charges).

Why does this matter to you? Because the position of a listing in the results directly depends on this score. A poorly filled listing or one with dark photos will be pushed to the bottom of the page, even if the property perfectly matches your search.

How to spot a well-ranked listing

Several clues can help distinguish a well-crafted listing from a hastily put together one:

  • The photos are bright, taken with a wide-angle lens, and show each room (not just the living room and the facade).
  • The description mentions the exact area, floor, orientation, amount of charges, and the result of the energy performance diagnosis.
  • The price is consistent with comparable properties in the neighborhood, indicating that the seller or agency has done serious estimation work.

If you are selling, paying attention to these elements mechanically increases the visibility of your listing on most portals, without paying extra.

DPE filter and thermal sieves: a strategic search criterion

Energy data has taken on considerable importance in real estate searches. Due to regulatory constraints on the most energy-consuming homes, several major portals have added the energy performance diagnosis (DPE) as a full-fledged search filter.

For a buyer, filtering by DPE allows for anticipating two things. First, the actual cost of occupying the property: a property rated F or G incurs significantly higher energy bills. Secondly, the rental restrictions that are gradually affecting thermal sieves.

Buying a thermal sieve: risky calculation or good deal

A property poorly rated on the DPE often negotiates below market price. The discount may seem attractive, but you need to factor in the cost of energy renovation work (insulation, heating replacement, ventilation) before concluding.

A portal that clearly displays the DPE and offers estimates of energy costs helps in making this calculation. Without this information, you are comparing properties that do not have the same actual usage cost, which skews the entire process.

Successful real estate project: data to check before contacting an agency

Even before picking up the phone or sending a message, a few checks on the portal can help filter the listings that deserve your attention.

  • The date of posting: a listing that has been online for several months may indicate a price that is too high or an undisclosed defect.
  • The price history, when offered by the portal: a recent drop indicates that the seller is willing to negotiate.
  • The consistency between the stated area and the number of rooms: a T3 of less than 45 m² raises questions about the actual layout.
  • The number of photos: fewer than five photos for an apartment is often a signal of an incomplete listing.

Cross-referencing these indicators reduces the number of unnecessary visits and focuses your energy on properties that truly match your project.

Adjusting your search in real time

Portals that offer personalized alerts allow you to react quickly when a property matching your criteria appears. In a tight market, well-priced properties with good DPE ratings sell within days. Setting up precise alerts is better than checking the portal manually every evening.

The choice of real estate portal determines the quality of the information you access, and thus the relevance of your decisions. A portal that displays quality scores, energy filters, and tracking data transforms a simple search into a true buying or selling strategy.
