Finding a property that truly matches one’s project requires going beyond simply reading listings. The search now involves a precise filtering process, where each criterion (location, energy performance, type of property, budget) acts as a disqualifying filter even before the first visit. Measuring the gap between what the market offers and what one is looking for can save considerable time and avoid unnecessary visits.
EPC and energy filtering: the criterion that changes the property search
Most real estate buying guides place budget and location at the top of the criteria. However, the energy performance diagnosis (EPC) has become a fully-fledged sorting filter, capable of eliminating or enhancing a property before any aesthetic considerations.

A property rated F or G implies energy renovation work, the cost of which can radically alter the total budget of the operation. Conversely, a property rated A or B reduces monthly charges and facilitates access to credit, with some banks applying more favorable conditions to high-performing homes.
By consulting the real estate listings on Immo et Habitat, it is possible to quickly identify properties according to their energy label and cross-reference this criterion with location or size. This filtering helps avoid wasting time on attractive listings that may be financially misleading once renovation costs are factored in.

| EPC Class | Impact on the purchase project | Point of caution |
|---|---|---|
| A or B | Low charges, easier financing | Purchase price often higher |
| C or D | Good compromise between performance and price | Check insulation and heating system |
| E | Moderate renovation work required | Estimate the cost of bringing up to standards |
| F or G | Major renovation required | Rental restrictions, potential depreciation upon resale |

New or old: compare according to your buyer profile, not the market
Standard comparisons pit new against old based on general criteria (notary fees, guarantees, charm). This framework becomes more useful when related to three concrete variables: timing, financing capacity, and tolerance for renovation work.
Buying new and timing constraints
A purchase in VEFA (sale in the future state of completion) imposes a delivery time that can exceed one year. For a buyer whose lease is expiring or who needs to synchronize a resale, this delay creates a financial risk: double rent, bridge loan, or temporary accommodation.
New properties, on the other hand, offer reduced notary fees and no immediate renovation work. The savings on notary fees rarely offset the higher cost per square meter when compared to similar size and location in older properties.
Old with renovation: an underestimated lever
Older properties allow for quick occupancy and generally lower price per square meter. A common pitfall is underestimating the cost of renovation work. A property rated E or F in EPC may require a renovation budget that negates the initial price advantage.
Cross-referencing the listed price with the EPC label and an estimate of renovation costs provides a more reliable picture of the actual cost. Listings that detail the EPC and the condition of the property allow for this calculation as early as the search phase, without waiting for the visit.
Refining your property search: filters that save time
The current trend is towards increasingly fine filtering of listings. Consulting hundreds of properties without precise criteria is like searching for a needle in a haystack. Three filtering axes stand out for their effectiveness.
- Location and mobility: beyond the city or neighborhood, commute time and proximity to transportation affect daily quality of life and the property’s long-term value.
- Energy performance as a disqualifying filter: immediately exclude properties whose EPC class would require work incompatible with the available budget.
- Usable area and layout: an identical gross area can hide significant differences in livability depending on room distribution, storage presence, or lighting.
Platforms that allow combining these filters reduce the number of necessary visits. Moving from several dozen viewed listings to a handful of properties that truly match one’s project represents a measurable time saving over several weeks of searching.

Seasonality of the real estate market and timing of the search
The volume of available listings varies according to the time of year. In winter, supply often exceeds demand, allowing for more room to negotiate the sale price. In spring, the number of buyers increases, and attractive properties sell faster.
Starting your search during a low season increases negotiating power. A property on the market for several months, spotted in January or February, offers leverage that the same property listed in April would not.
This seasonality also affects the type of properties available. Houses with gardens appear more in spring (sellers betting on brightness and vegetation to attract buyers), while city-center apartments follow a more regular rhythm throughout the year.
Adapting your search calendar to the type of property targeted and local competitive pressure remains an underutilized lever. Cross-referencing this temporal data with search filters allows for identifying opportunities before they become visible to the majority of buyers.
The choice of property relies less on intuition than on the ability to structure one’s search. Defining disqualifying criteria before consulting any listings transforms a often scattered approach into a targeted process, where each scheduled visit has a real probability of leading to a purchase offer consistent with one’s budget and life project.
