Frequently asked questions

What is a square metre worth in Onnion?
Over the 40 published sales of flats above, the median is €3,108 per square metre. The municipality counts fewer than 25 housing sales over twelve months, so Briveo does not turn it into a market index and shows the sales themselves, with the nearby towns above the threshold.
How do I value a property in Onnion?
By reading the published sales of the municipality and of the nearby towns, at comparable surface and type, then asking Briveo for a valuation, which reads the sales of the area and visits the property.
How much is a flat worth in Onnion?
Over the 40 published sales of flats above, the median is €3,108 per square metre, half of them between €2,623 and €3,565. A given property sits above or below, by its surface, its condition and its plot, and that is what the valuation settles.
How do I sell a property in Onnion with Briveo?
Briveo values the property on the sales of the area, publishes the listing and shows the property, under an electronic mandate signed online. The fees are due at the deed.
