Between Morges and Préverenges, Lonay marries a preserved village with residential districts a stone's throw from the lake.
At CHF 10,600 per m² for a flat, Lonay sits in the upper band of the Vaud market. That level usually goes with scarce building land and few sales, so a valuation rests on a thin set of comparables. The premium over Vaud has a practical effect at resale. Buyers arriving from cheaper communes negotiate hard on condition, because they are already stretched on the price per square metre before they walk in. Lonay ranks 37 out of 132 communes in Vaud on flat prices per m². Rankings shift a place or two from one year to the next without anything real changing, so read the band rather than the exact position.
The last twelve months added 2.8 percent in Lonay. Rises of this order usually come from a shortage of listings rather than from a wave of new buyers, and they unwind faster than they build. Within the Morges district, Lonay lands 10 percent from the local median. A cantonal average mixes city and countryside, so it flatters some communes and penalises others. The district figure removes most of that distortion.
No single period defines Lonay, though 1946-1960 leads with 16 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune. At 3.6 rooms and 104 m² on average, homes in Lonay are sized for households rather than single occupants. If you are looking for a studio or a two-room flat, expect a thinner choice and less room to negotiate.
The median flat in Lonay comes out at CHF 10,600 per m², a gap of 15 percent against the Vaud median. That figure covers every flat sold, whatever the floor, the age of the building or the state of the kitchen. The 25-year record opens at CHF 3,800 and closes at CHF 9,500, +150 percent apart. Use it to sanity-check an estimate rather than to project forward, since nothing in the series promises the next decade repeats it. Enough properties change hands in Lonay each year to keep the price data steady. Estimates land in a narrower range here, and a valuation can lean on recent comparable sales instead of falling back on the cantonal average.
In Lonay the difference between two flats on the same street can run into six figures. Getting your own number, rather than reading the commune median, is what makes that difference visible before you set a price.

16 percent of homes in Lonay date from 1946-1960. That age band sets the technical agenda for a buyer here, since insulation, heating system and windows are what decide running costs for the next twenty years.
