A first opinion in 3 minutes, a precise valuation after a visit.
The form gives you a first indication of price. In the Marais, it is a starting point, not a sale price: two apartments on the same street can have very different values depending on the floor, the quiet, the light or the condition.
Nicolas Borge then calls you back to arrange a visit. You receive your written valuation within 48 hours.
What the online valuation takes into account: location, surface area, floor, the condition of the property and of the building (co-ownership), recent sales in the area, current listings and the value for an investor.
A valuation starts with a careful reading of your property
In the Marais, two apartments on the same street can be worth very different prices. The floor, the light, the quiet, the condition of the building: everything counts. That is why every valuation follows a rigorous four-step approach.
1. A first meeting, at your home
We take the time to visit your apartment: its volumes, exposure, view, condition and any works needed. We also listen to your plans, your timeline and what matters to you in this sale.
2. A study of the real market around your address
We rely on the sales actually signed in your area over the last two years (DVF database, the French government transaction data), expressed per Carrez area (legal living area) as well as per built area. We also look at the properties currently for sale: those are what buyers will compare yours with.
3. A property-by-property analysis
An average neighbourhood price does not tell the value of an apartment. We refine it by floor, exposure, energy rating (DPE), level of works, service charges and the situation of the building (general-meeting minutes, voted works, works fund).
4. A written report within 48 hours
At a second meeting, we hand you a detailed valuation, as a range with a target value. It combines four perspectives: the comparative study, the value sought by a buyer who falls for the property, the value for an investor and the real budget of buyers in the area. It comes with a selling strategy: the asking price to choose and the timeline to expect.
Our commitment: to give you a sincere, well-argued opinion on the value of your property, so you can sell under good conditions, at the right price and within a controlled timeframe.
Prices in the Marais in 2025
In 2025, an apartment sold at a median €12,550/m² in the 3rd and 4th arrondissements: €12,085/m² in the 3rd, €12,920/m² in the 4th (source: DVF database, prices excluding agency fees). The neighbourhood-by-neighbourhood detail, with our sales, is on our pages Marais, Saint-Paul and Place des Vosges, Haut-Marais, Hôtel de Ville and Saint-Merri and Bastille.
Why the right price from day one
An apartment priced too high attracts few visits, stays online and ends up selling below its value, after price cuts that worry buyers. At the right price, it sells fast: on our recent sales, the first offer came between three weeks and four months after the mandate was signed, including for properties needing renovation.
Frequently asked questions
Is the valuation free?
Yes, online or with a visit, and with no commitment on your side.
Online valuation or with a visit: what is the difference?
The online valuation gives you a first opinion. It takes into account location, surface area, floor, the condition of the property and of the building, recent sales, current listings and the value for an investor, based on what you declare. It sees neither the light, nor the quiet, nor the real condition observed on site. The valuation with a visit includes all of that: it is what allows us to set a listing price.
Which documents should I prepare?
Your title deed, the diagnostics (including the DPE energy rating), the last three general-meeting minutes of the co-ownership, the amount of service charges and your latest property tax bill. None of this is required for the first meeting, but it makes the valuation more precise.
How long until I get my valuation?
The first online opinion appears in a few minutes. The written valuation is handed to you within 48 hours after the visit.
