Prices by property type in Lagny-sur-Marne

By property type in Lagny-sur-Marne: T2 at €3,912/m², T3 at €3,603/m², studio at €4,167/m², T4 at €3,150/m², T5+ at €2,776/m².

The studio carries the highest price per square metre and the T5+ the lowest, a gap of 50 %. Small units usually cost more per square metre than large ones, because the price of a kitchen and a bathroom is spread over fewer metres.

Selling in Lagny-sur-Marne

Pricing in Lagny-sur-Marne starts by placing your property inside the €3,153 to €4,313 band rather than on the median alone. The median describes the middle of the market; condition, floor, outdoor space and energy rating decide where in the band you sit.

With 557 sales a year, Lagny-sur-Marne absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.

Buying in Lagny-sur-Marne

Reading the €3,153 to €4,313 band is a buyer’s main tool in Lagny-sur-Marne. A property at the bottom is not a bargain and one at the top is not a rip-off: the band measures how different the properties are, not how well they are priced.

Prices moving up narrow the room for negotiation without closing it: a property that has been on the market a long time is negotiable whatever the trend says.

Acquisition costs are budgeted on top of the price: around 8 % on an existing property, around 3 % on a new one. These are orders of magnitude; the notary computes the exact amount.

How the Lagny-sur-Marne market is moving

Over the last twelve months the median moved by +5.3 %. A move of that size over a single year often reflects a change in what is being sold as much as a change in value.

No five-year reading is available for Lagny-sur-Marne: published sales do not go back far enough with enough volume, so the long-term direction cannot be stated here.

Among the towns tracked by BRIVEO in the same department, on the median apartment price, Melun sits 32 % below and Serris 23 % above. Those are the gaps a buyer widening their search area actually meets.
