How to estimate a property in Lasne
Estimating a property in Lasne means starting from the price observed for comparable properties in the municipality, then correcting that benchmark for the features of the home.
The starting point is the price per square metre recorded on recent sales of the same type, house or apartment. That benchmark describes an average property, not a specific home.
Then come the corrections. Living area, plot, number of bedrooms, general condition, energy performance, garage or outdoor space, each one shifts the value.
An estimate remains a range. The price settles where that range meets demand at the time the property goes on the market.

What makes an estimate vary from one address to the next
With equal features, two properties in the same municipality are not worth the same price, and the precise location as well as the technical condition explain most of the gap.
Location plays on the distance to schools, shops and main roads, but also on how quiet the street is.
Technical condition weighs through the work it imposes on the buyer. Roof, window frames, heating and insulation can partly be read in the EPC certificate, and a weak rating is negotiated on the price.
These factors do not add up mechanically. A well-located property in need of renovation and a renovated one further out end up in the same range.
