Buying in Osny
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.
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.

Over the last twelve months the median moved by +10.3 %. 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 Osny: published sales do not go back far enough with enough volume, so the long-term direction cannot be stated here.
